HLG-150H-24A is a 150W LED AC to DC power supply with constant current output and constant voltage output design as its main features It can work at an input voltage of 90~305VAC. It has a high conversion efficiency of up to 94%. It adopts a fanless design and can work under natural air cooling Metal shell and IP67IIP65 high protection grade design make it suitable for indoor or outdoor applications. Can be used for LED street lighting, LED overhead lighting, parking lot lighting, LED fishing lights, LED greenhouse lighting. Equipped with a variety of functional options (such as several dimming methods) to provide the best design flexibility for the lighting system DC voltage: 24V, Constant current range: 12-24V, Rated current: 6.3A, Rated power:151.2W, Ripple and noise: 150mVp-p, Voltage adjustment range: 22~27V, Voltage accuracy: +1.0%, Linear adjustment rate: ±0.5%, Load regulation: ±0.5% Start/rise time: 1000ms, 50ms/115VAC 500ms, 50ms/230VAC (at full load); Type B: 1000ms, 200ms/115VAC 500ms, 200ms/230VAC (at 95% load), Holding time 16ms (at full load) 230VAC/115VAC, Current adjustment range: 3.8~6.3A: can be adjusted by internal potentiometer (type A only), Voltage range: 90~305VAC or 127~431VDC, Frequency range: 47~63HZ, Efficiency: 93% (Due to different batches, the printed words on the product will be different, which does not affect use) AC current: 1.7A1115VAC 0.75A1230VAC 0.7A1277VAC Overvoltage: 28~34V; protection mode: shut down the output voltage, automatically recover or recover after restarting Over temperature: Turn off the output voltage, and it will automatically recover after the temperature drops. Short circuit: constant current limit, automatic recovery after abnormal conditions are removed Overcurrent: 95~108%; protection mode: constant current limit, automatic recovery after abnormal load
