Full ordering model NPB-360-12AD1; NPB-360 series, 12 V nominal battery class, AD1 output.
Default boost charge voltage 14.4 V.
Default float charge voltage 13.8 V.
Default charging current 20 A, typical catalogue output-current setting.
Max. output power 304 W; input-voltage and temperature derating apply.
Voltage adjustment 10.5–15.2 V using the front Vo Adj. control.
Charging-current adjustment 10–20 A (50–100%) using the front Io Adj. control.
Suggested battery capacity 65–195 Ah; confirm the battery manufacturer’s maximum charging current and charging profile.
Typical efficiency 87% for this AD1 configuration at the stated default test conditions.
Typical leakage from battery Less than 1 mA.

The 12 V designation is the nominal battery class, not the actual boost or float charging voltage. Select the charging voltage and current for the specific battery; voltage adjustment does not increase the current limit or maximum available power.

Charging Modes and Status

Factory charging mode Three-stage charging; the front 3 Stage 2 switch selects two-stage or three-stage operation.
Two-stage profile Constant current followed by constant voltage at Vfloat; the catalogue diagram marks 10% of CC at the red-to-green transition.
Three-stage profile Constant current, constant voltage at Vboost, then float at Vfloat. The diagram marks 10% of CC at the transition to float.
Status LED Red during charging stages 1 and 2; green at stage 3 float or when the battery is full.

The catalogue describes two-stage charging for lithium batteries such as lithium iron and lithium manganese types, and three-stage charging for lead-acid flooded, gel and AGM batteries. Battery specifications may require different settings; confirm compatibility with the battery manufacturer and MEAN WELL.

Input and Protection

Input voltage / frequency 90–264 VAC or 127–370 VDC; AC frequency 47–63 Hz.
AC connection Class I design with FG; IEC 320-C14 inlet and AC switch.
Power factor / inrush control Built-in active PFC and active inrush-current limiting; typical PF >0.98 at 115 VAC and >0.95 at 230 VAC, full load.
Typical AC input current 4.5 A at 115 VAC; 2.2 A at 230 VAC.
Typical cold-start inrush 50 A at 230 VAC.
Input leakage current Less than 0.75 mA at 240 VAC.
Power consumption with AC switch OFF Less than 0.15 W.
Short circuit Constant-current limiting; shutdown after 5 seconds, then re-power to recover. This protection description applies to a short circuit occurring after the charger is turned on.
Overvoltage 16–20 V; output shutdown and latch-off, followed by re-powering to recover.
Overtemperature Hiccup operation; automatic recovery after the temperature decreases.
Reverse battery polarity Protection by opening the internal fuse.

Cooling, Environment and Load Limits

Cooling Built-in fan. Typical control uses internal RTH3: fan ON at ≥50°C and OFF at ≤45°C; these are internal sensor temperatures, not ambient-temperature ratings.
Working temperature -30°C to +70°C with derating; horizontal installation for the plotted thermal curves.
Horizontal temperature curve 100% load from -30°C to +45°C. The plotted points are 80% at +50°C, 65% at +60°C and 40% at +70°C.
Input-voltage load curve At 60 Hz: 90% load at 90 VAC, reaching 100% at 100 VAC and remaining at 100% through 264 VAC, before temperature derating.
Working humidity 20–95% RH, non-condensing.
Storage temperature / humidity -40°C to +85°C; 10–95% RH, non-condensing.
Temperature coefficient ±0.05%/°C from 0°C to +45°C.
Vibration 10–500 Hz, 2 G; 10-minute cycle, 60 minutes each along X, Y and Z.

Apply input-voltage and temperature limits together. Keep the charger’s ventilation path clear; the operating-temperature range is not a full-power rating at every temperature.

Dimensions, Connections and Mounting

Body dimensions, L × W × H 182.7 × 96 × 49 mm; case PS-120F. Drawing dimensions are in mm with ±1 mm tolerance.
Standard output connection Anderson 1327 red and 1327G6 black housings, or equivalent; Anderson 261G2 (45 A) contacts, or equivalent. Red: +V; black: −V. The contact rating is not the charger output-current rating.
Output cable 100 ±5 cm output cable, as shown for the AD1 version.
Catalogue unit packing reference 1300 g per unit. The separate carton entry is 10 pieces / 14 kg / 1.13 CUFT.
Optional mounting bracket PGG2MHS012D, ordered separately. The installation uses four brackets per charger; this is an installation quantity, not a stated sales-pack quantity.
Bracket installation drawing The diagram uses M3 × 4 screws and marks four M3 holes with L=5. The side view marks 106.4 mm between mounting positions and 44.65 mm from the case edge to the first position. See physical catalogue page 20.

Use the indicated positive and negative output connections. The mounting-bracket listing does not specify a separate supplied fastener set; confirm the required mounting hardware with the order.

Factory-Customized DC Connector Options

R7B Locking male mini-DIN 4-pin; KYCON KPPX-4P equivalent. Pins 1/4 +Vo and 2/3 −Vo; output current <7 A.
XLR3 3-pin XLR; pins 1/2 +Vo and pin 3 −Vo. Output current <10 A.
D3P DIN 3-pin; pin 1 +Vo, pins 2/3 −Vo; output current <7 A.
D2P DIN 2-pin; pin 1 −Vo, pin 2 +Vo; output current <5 A.
INL3 DIN 3-pin DC connector; N +Vo, L −Vo; output current <10 A. These are DC plug markings.
C4P AMP 1-480702-0 (6.35 mm) equivalent; pins 1/2 +Vo and 3/4 −Vo; output current <7 A. FG is not connected to this output connector.

These DC alternatives are available through customization and are separate from this AD1 standard configuration. Match voltage, polarity and the actual selected charging current to the strict connector limits shown; a connector option does not increase available charger power or current. This model adjusts from 10 A to 20 A, so none of the listed alternatives with a limit below 10 A can be assumed suitable within that range; obtain a confirmed factory configuration for a different connector.
