Product Datasheet Download MEAN WELL ENC-360 Datasheet (PDF) The ENC-360 section is on PDF pages 35, 36, 37, 38, 39, 40. Refer to the complete mechanical drawings and notes when planning installation. Charging Output and Battery Selection Complete model ENC-360-48 Nominal voltage class 48 V Default boost charge voltage 57.6 V Default float charge voltage 55.2 V Rated charging current 6 A Rated output power 345.6 W Programmable boost or float range 36–60 V Suggested battery capacity 25–65 Ah Typical battery leakage current Less than 1 mA Typical efficiency 94% The voltage range applies to programming Vboost or Vfloat with the SBP-001 smart battery charging programmer; it is not a separate continuously adjustable front-panel output. The listed battery-capacity range is a recommendation, not a substitute for checking the battery manufacturer’s maximum charging current. The catalogue identifies flooded, gel and AGM lead-acid batteries, and lithium-ion batteries described as lithium iron and lithium manganese. Select a charging profile approved for the particular pack, chemistry and battery-management requirements. Modification of charger specifications may be needed; consult the battery supplier and MEAN WELL. A nominal voltage match alone does not establish compatibility. Three-Stage Charging and DIP Presets DIP 1 OFF / DIP 2 OFF Default programmable: 57.6 V boost / 55.2 V float DIP 1 ON / DIP 2 OFF Gel preset: 56 V boost / 54.4 V float DIP 1 OFF / DIP 2 ON Flooded preset: 56.8 V boost / 53.6 V float DIP 1 ON / DIP 2 ON AGM preset: 58 V boost / 54 V float Default CC value for these curves 6 A Status indicator Orange: charging in stage 1 or 2; green: float in stage 3 Stage 1 supplies constant current while battery voltage rises to Vboost. Stage 2 holds Vboost while current falls. The published curve changes to stage 3 at 10% of the CC setting, reducing voltage to Vfloat. Green identifies the float stage rather than an independently measured state of charge for every battery chemistry. To alter the default charging curve, use the MEAN WELL SBP-001 smart battery charging programmer with a personal computer. Select programming and interconnection accessories for this charger; the charger order number does not itself include the programmer or computer. The other three predefined profiles are selected with the two-position DIP switch. Input and Power Factor Input range 90–264 VAC or 127–370 VDC AC frequency 47–63 Hz Typical AC input current 3.8 A at 115 VAC; 1.9 A at 230 VAC Active PFC, typical power factor PF >0.98 at 115 VAC and >0.95 at 230 VAC, at full load Typical cold-start inrush current 80 A at 230 VAC Leakage current Less than 3.5 mA at 240 VAC The mechanical drawing shows an AC inlet, power switch and frame-grounded metal enclosure. Use the inlet and protective-earth arrangement shown in the product drawing. Input-current and efficiency figures are typical, under the stated catalogue test conditions. Protection and Temperature Compensation Short circuit Output shutdown; re-power to recover. This mechanism is specified for a short circuit occurring after the charger has been turned on. Overvoltage range 62.1–72.9 V; output shuts down and latches off; re-power to recover Overtemperature Output shutdown; automatic recovery after temperature falls Reverse battery polarity Protection by an internal fuse Battery under- and overvoltage Listed protection functions; battery-specific threshold suitability must be confirmed Temperature compensation Built-in function using an NTC sensor The MCU-controlled dynamic overvoltage protection is approximately 115% of Vboost during constant-current and constant-voltage stages, and 115% of Vfloat during float charging. These protection levels do not replace the selected battery charging limits. Connect the NTC circuit to CN31 RTH+ and RTH− using the matching sensor assembly. No numerical temperature-compensation slope or battery under-/overvoltage cutoff is specified in these pages. Cooling and Derating Cooling Fanless, free-air convection Working temperature −30 to +70°C, subject to derating Horizontal installation curve 100% load from −30 to +50°C; reduce linearly to 60% at +70°C AC input curve at 60 Hz 90% load at 90 VAC; 100% at 100 VAC and from 100 to 264 VAC Allow free airflow around the charger and apply temperature and low-input restrictions together. The AC graph does not establish a separate DC-input derating curve. For this fanless model above 2000 m, reduce permissible ambient temperature by 3.5°C per additional 1000 m. This adjustment is not an unrestricted maximum-altitude rating.

Three-Stage Charging and DIP Presets DIP 1 OFF / DIP 2 OFF Default programmable: 57.6 V boost / 55.2 V float DIP 1 ON / DIP 2 OFF Gel preset: 56 V boost / 54.4 V float DIP 1 OFF / DIP 2 ON Flooded preset: 56.8 V boost / 53.6 V float DIP 1 ON / DIP 2 ON AGM preset: 58 V boost / 54 V float Default CC value for these curves 4 A Status indicator Orange: charging in stage 1 or 2; green: float in stage 3 Stage 1 supplies constant current while battery voltage rises to Vboost. Stage 2 holds Vboost while current falls. The published curve changes to stage 3 at 10% of the CC setting, reducing voltage to Vfloat. Green identifies the float stage rather than an independently measured state of charge for every battery chemistry. To alter the default charging curve, use the MEAN WELL SBP-001 smart battery charging programmer with a personal computer. Select programming and interconnection accessories for this charger; the charger order number does not itself include the programmer or computer.

The MEAN WELL ENC-180-48 is a fanless programmable desktop battery charger for the 48 V nominal battery class. Its default three-stage profile uses 57.6 V boost charging, 55.2 V float charging and 3 A constant current, with a rated output power of 172.8 W. Select the charging curve and temperature compensation to suit the battery. Product Datasheet Download MEAN WELL ENC-180 Datasheet (PDF) The ENC-180 section is on PDF pages 23, 24, 25, 26, 27, 28. Refer to the complete mechanical drawings and notes when planning installation. Model and Charging Output Complete model ENC-180-48 Model code ENC-180 identifies the programmable desktop charger series; 48 identifies the nominal battery-voltage class. Default boost charge voltage 57.6 V Default float charge voltage 55.2 V Rated charging current 3 A Rated output power 172.8 W Programmable charge-voltage range 36–60 V for Vboost or Vfloat, using SBP-001. Suggested battery capacity 15–35 Ah Typical battery leakage current Less than 1 mA Typical efficiency 93% The 48 V model designation is a nominal battery class, not a fixed charging-output voltage. Select a battery pack whose charge limits match the actual boost and float settings, the 3 A default current and the required temperature compensation. The catalogue identifies flooded, gel and AGM lead-acid batteries, and lithium-ion types described as lithium iron and lithium manganese. Compatibility depends on the complete battery specification and its protection requirements; consult the battery manufacturer and MEAN WELL about settings and maximum permissible charging current. The suggested capacity range does not replace that check. Three-Stage Charging and Curve Selection DIP 1 OFF / DIP 2 OFF Default programmable curve: Vboost 57.6 V; Vfloat 55.2 V; default CC 3 A. DIP 1 ON / DIP 2 OFF Predefined gel curve: Vboost 56 V; Vfloat 54.4 V. DIP 1 OFF / DIP 2 ON Predefined flooded-battery curve: Vboost 56.8 V; Vfloat 53.6 V. DIP 1 ON / DIP 2 ON Predefined AGM curve: Vboost 58 V; Vfloat 54 V. Stage 1 charges at constant current while voltage rises. Stage 2 holds Vboost and allows charging current to fall. The default diagram marks the transition to stage 3 at 10% of the selected CC level; stage 3 then holds the lower Vfloat voltage. The status LED is orange during stages 1 and 2, and green during the float stage. Green indicates the charger's stage, not a universal state-of-charge measurement for every battery chemistry. The embedded curve table specifies 3 A as the default CC setting for this model. The two-position DIP switch selects the default programmable curve or one of the three predefined battery curves shown above. Changing the default charging-curve parameters requires the MEAN WELL SBP-001 smart battery charging programmer and a personal computer. These programming tools are not listed as supplied charger accessories. Select the charging profile for the battery before operation; the programmable voltage range is not a guarantee of suitability for every battery within it. AC/DC Input Input voltage 90–264 VAC or 127–370 VDC; apply low-input derating. Input frequency 47–63 Hz Typical power factor PF >0.98 at 115 VAC; PF >0.95 at 230 VAC, at full load. Typical AC input current 1.9 A at 115 VAC; 0.95 A at 230 VAC. Typical cold-start inrush 70 A at 230 VAC Input leakage current Less than 3.5 mA at 240 VAC Active power factor correction is built in. Use the grounded AC inlet and protective-earth connection shown in the mechanical and block diagrams, and keep access to the power switch and input connection.

Its default three-stage profile uses 28.8 V boost charging, 27.6 V float charging and 6 A constant current, with a rated output power of 172.8 W. Select the charging curve and temperature compensation to suit the battery. Product Datasheet Download MEAN WELL ENC-180 Datasheet (PDF) The ENC-180 section is on PDF pages 23, 24, 25, 26, 27, 28. Refer to the complete mechanical drawings and notes when planning installation. Model and Charging Output Complete model ENC-180-24 Model code ENC-180 identifies the programmable desktop charger series; 24 identifies the nominal battery-voltage class. Default boost charge voltage 28.8 V Default float charge voltage 27.6 V Rated charging current 6 A Rated output power 172.8 W Programmable charge-voltage range 18–30 V for Vboost or Vfloat, using SBP-001. Suggested battery capacity 25–65 Ah Typical battery leakage current Less than 1 mA Typical efficiency 92% The 24 V model designation is a nominal battery class, not a fixed charging-output voltage. Select a battery pack whose charge limits match the actual boost and float settings, the 6 A default current and the required temperature compensation. The catalogue identifies flooded, gel and AGM lead-acid batteries, and lithium-ion types described as lithium iron and lithium manganese. Compatibility depends on the complete battery specification and its protection requirements; consult the battery manufacturer and MEAN WELL about settings and maximum permissible charging current. The suggested capacity range does not replace that check. Three-Stage Charging and Curve Selection DIP 1 OFF / DIP 2 OFF Default programmable curve: Vboost 28.8 V; Vfloat 27.6 V; default CC 6 A. DIP 1 ON / DIP 2 OFF Predefined gel curve: Vboost 28 V; Vfloat 27.2 V. DIP 1 OFF / DIP 2 ON Predefined flooded-battery curve: Vboost 28.4 V; Vfloat 26.8 V. DIP 1 ON / DIP 2 ON Predefined AGM curve: Vboost 29 V; Vfloat 27 V. Stage 1 charges at constant current while voltage rises. Stage 2 holds Vboost and allows charging current to fall. The default diagram marks the transition to stage 3 at 10% of the selected CC level; stage 3 then holds the lower Vfloat voltage. The status LED is orange during stages 1 and 2, and green during the float stage. Green indicates the charger's stage, not a universal state-of-charge measurement for every battery chemistry. The embedded curve table specifies 6 A as the default CC setting for this model. The two-position DIP switch selects the default programmable curve or one of the three predefined battery curves shown above. Changing the default charging-curve parameters requires the MEAN WELL SBP-001 smart battery charging programmer and a personal computer. These programming tools are not listed as supplied charger accessories.

The MEAN WELL ENC-120-24 is a fanless programmable desktop battery charger for the 24 V nominal battery class. Its default three-stage profile uses 28.8 V boost charging, 27.6 V float charging and 4 A constant current, with a rated output power of 115.2 W. Select the charging curve and temperature compensation to suit the battery. Product Datasheet Download MEAN WELL ENC-120 Datasheet (PDF) The ENC-120 section is on PDF pages 17, 18, 19, 20, 21, 22. Refer to the complete mechanical drawings and notes when planning installation. Model and Charging Output Complete model ENC-120-24 Model code ENC-120 identifies the programmable desktop charger series; 24 identifies the nominal battery-voltage class. Default boost charge voltage 28.8 V Default float charge voltage 27.6 V Rated charging current 4 A Rated output power 115.2 W Programmable charge-voltage range 18–30 V for Vboost or Vfloat, using SBP-001. Suggested battery capacity 15–40 Ah Typical battery leakage current Less than 1 mA Typical efficiency 90% The 24 V model designation is a nominal battery class, not a fixed charging-output voltage. Select a battery pack whose charge limits match the actual boost and float settings, the 4 A default current and the required temperature compensation. The catalogue identifies flooded, gel and AGM lead-acid batteries, and lithium-ion types described as lithium iron and lithium manganese. Compatibility depends on the complete battery specification and its protection requirements; consult the battery manufacturer and MEAN WELL about settings and maximum permissible charging current. The suggested capacity range does not replace that check. Three-Stage Charging and Curve Selection DIP 1 OFF / DIP 2 OFF Default programmable curve: Vboost 28.8 V; Vfloat 27.6 V; default CC 4 A. DIP 1 ON / DIP 2 OFF Predefined gel curve: Vboost 28 V; Vfloat 27.2 V. DIP 1 OFF / DIP 2 ON Predefined flooded-battery curve: Vboost 28.4 V; Vfloat 26.8 V. DIP 1 ON / DIP 2 ON Predefined AGM curve: Vboost 29 V; Vfloat 27 V. Stage 1 charges at constant current while voltage rises. Stage 2 holds Vboost and allows charging current to fall. The default diagram marks the transition to stage 3 at 10% of the selected CC level; stage 3 then holds the lower Vfloat voltage. The status LED is orange during stages 1 and 2, and green during the float stage. Green indicates the charger's stage, not a universal state-of-charge measurement for every battery chemistry. The embedded curve table specifies 4 A as the default CC setting for this model. The two-position DIP switch selects the default programmable curve or one of the three predefined battery curves shown above. Changing the default charging-curve parameters requires the MEAN WELL SBP-001 smart battery charging programmer and a personal computer. These programming tools are not listed as supplied charger accessories. Select the charging profile for the battery before operation; the programmable voltage range is not a guarantee of suitability for every battery within it. AC/DC Input Input voltage 90–264 VAC or 127–370 VDC; apply low-input derating. Input frequency 47–63 Hz Typical power factor PF >0.98 at 115 VAC; PF >0.95 at 230 VAC, at full load. Typical AC input current 1.25 A at 115 VAC; 0.63 A at 230 VAC. Typical cold-start inrush 65 A at 230 VAC Input leakage current Less than 3.5 mA at 240 VAC Active power factor correction is built in. Use the grounded AC inlet and protective-earth connection shown in the mechanical and block diagrams, and keep access to the power switch and input connection. Unless otherwise stated, the published specifications are measured at 230 VAC, rated load and 25°C ambient. Protection and Battery Temperature Compensation Short circuit Output shuts down; re-power to recover. This specification applies to a short circuit occurring after the charger is turned on. Specified overvoltage range 31–36.5 V; output shuts down and latches off, requiring re-powering to recover.
