Output and selection

Model and function I denotes the India version with input overvoltage protection; AB combines a current-setting potentiometer and isolated 3-in-1 dimming.
Rated output power 25 W. Apply the published thermal limits.
Output current 700 mA default. 0.25–1.05 A via the built-in current adjustment potentiometer. This range must be combined with the I–V operating envelope.
Constant-current voltage region 22–54 V. Keep voltage × current within the 25 W rating and the shaded I–V region. The full current/voltage rectangle is not usable.
Open-circuit voltage 57 V maximum.
Output current ripple 5.0% maximum at rated current.
I–V selection boundary The published envelope includes 250 mA/54 V, 500 mA/22 V and 1050 mA/22 V boundary points. At low current the minimum usable voltage rises; choose within the shaded area and the 25 W rating.
Startup Setup 500 ms; rise 100 ms at 115 VAC / 230 VAC. Setup is measured at first cold start; repeated switching can increase it.

Input and performance

Input supply 90–305 VAC; 127–431 VDC. AC frequency 47–63 Hz. Active PFC.
Input derating The 60 Hz static curve shows full load from 90 to 305 VAC; thermal limits still apply.
Power factor At full load: PF ≥0.97 at 115 VAC, ≥0.95 at 230 VAC and ≥0.92 at 277 VAC.
Total harmonic distortion THD <10% at load ≥50% for 115/230 VAC, or load ≥75% for 277 VAC.
Input current 0.29 A / 115 VAC; 0.15 A / 230 VAC; 0.13 A / 277 VAC.
Inrush current Typical cold start 50 A at 230 VAC; width 350 µs at 50% peak, per NEMA 410.
16 A circuit breaker loading 5 units on type B and 8 on type C at 230 VAC, as listed in this datasheet.
Leakage current <0.75 mA at 277 VAC.
No-load / standby consumption No-load consumption <0.75 W for the I version. Dimming-off standby consumption <0.5 W for AB type.

Protection

Short-circuit protection Constant-current limiting; automatically recovers after the fault is removed.
Overpower protection 110–150% overpower protection; automatically recovers after the fault is removed.
Overtemperature protection Hiccup operation; automatically recovers after the fault is removed.
Overcurrent protection Constant-current limiting; automatically recovers after the fault is removed.
Input overvoltage protection 320–370 VAC threshold; output shuts down when input exceeds the protection threshold and recovers automatically after removal of the fault. The I version can withstand 440 VAC input stress for 48 hours; this is a survival test, not its normal operating input range.

Operating conditions

Case temperature Tcase −40 to +85°C; maximum case temperature +85°C. Case temperature and ambient temperature are different limits.
Ambient derating Horizontal mounting: full load through 60°C ambient, reducing to 60% at 70°C. The cold region from −40 to −25°C is marked for 230 VAC input only. Keep the case within its stated limit.
Cooling and altitude Natural air convection. Above 2000 m altitude, reduce permitted ambient temperature by 3.5°C per additional 1000 m for this fanless model.
Humidity and storage Working humidity 20–95% RH non-condensing. Storage temperature −40 to +80°C.
Temperature coefficient ±0.03%/°C over 0–60°C.
Vibration 10–500 Hz, 5 G, 12 minutes per cycle; 72 minutes along each X, Y and Z axis.
Lifetime and warranty Catalog typical life expectancy >50,000 hours with the marked tc point about 80°C or lower. Five-year manufacturer warranty, subject to its warranty terms. Lifetime decreases as case temperature increases.
Reliability 3931.6 K hours minimum by Telcordia SR-332; 399.9 K hours minimum by MIL-HDBK-217F at 25°C. MTBF is not a service-life guarantee.

Control and adjustment

Current setting Set the rated current with the built-in Io ADJ potentiometer; preserve the adjustment seal and the published I–V and temperature limits.
Dimming interface AB type: isolated 3-in-1 current dimming between DIM+ (purple) and DIM− (pink). Use 0–10 VDC, a 10 V PWM signal at 100 Hz–3 kHz, or an external resistance. Typical dimming-source current 100 µA.
Dimming limits Minimum defined dimming level approximately 8%; current is undefined between 0% and 8%. Output can fall to 0% at approximately 0 Ω, 0 VDC, or a 10 V PWM signal with 0% duty cycle.
Dimming connection Do not connect DIM− to V−. Direct connection to the LEDs is suggested; this dimming arrangement is not suitable for an additional downstream driver.
Synchronized resistance dimming The plotted resistance scale is 10 kΩ/N through 100 kΩ/N, where N is the number of drivers in synchronized dimming. The control source must support the combined dimming-source current and the required insulation.

Installation manual requirements

Installation safety Disconnect the mains supply and prevent accidental reconnection before installation or maintenance. Have faults examined by a qualified technician; do not open the power-supply case yourself.
Ventilation and mounting Keep ventilation clear and do not stack objects on the unit. Keep 10–15 cm clearance when the adjacent device is a heat source. Follow this model’s mounting, ambient-temperature and output-derating requirements.
System wiring and protection Use approved primary and secondary wiring rated for at least the applicable unit current. Provide suitable system-level insulation and an enclosure around single-insulated wiring; verify EMC again in the completed system. Connect a fitted FG lead to protective earth according to the model wiring; the manual exempts only units marked Class II and ungrounded.
Environmental and load limits Do not immerse the unit or install it near fire or above its specified ambient limit. Keep output current and power within the model’s rated operating envelope. If a fitted external flexible cable is damaged, replacement is limited to the manufacturer, its service agent or a similarly qualified person.
Connection seals and support If waterproof connectors are fitted, secure their connections to prevent water entry. Verify the mounting structure and luminaire strength; use safety cables for bay-light applications.
Adjustable-unit weather protection This IP67 model has a built-in adjustment function. Install it indoors or in a location sheltered from rain outdoors, as required by the installation manual. IP67 does not permit immersion.
Dimming-controller installation Verify that the controller can drive the actual interface and number of units. For standalone use with dimming conductors smaller than 18 AWG (0.75 mm²), use SELV controllers/networks; contact MEAN WELL for guidance before using FELV control. Follow this exact model’s dimming method and wiring.

Confirm the exact LED load, operating temperature, control interface and installation requirements against the linked datasheet and manual before commissioning.
