Product Details

class 2 led power supply


Features:

Delivers smooth, stable, flicker-free dimming with soft start and desirable fade-on performance

When a dimmer is set to full brightness, there is no loss of top-end light output

No minimum lighting load required for wide range dimming

Auto reset protection in case of lighting overload, open circuit, short circuit, over-temperature or over voltage

ETL listed for dry or damp locations. (Indoor use only)

Direct wire configuration (with case)

Rated for 30,000 hours when at 80% power, 24 hours a day; 50,000 hours if only on 8~12 hours a day

Constant Voltage Output

Universal AC input: 100~130 VAC

Power Factor > 0.8

Why did the power supply shuts down during operation and after turning it off, I can restart the power supply again?

Ans: In general there are two circumstances that will cause the power supply to shut down. The first one is the activation of the over-load-protection (OLP). To deal with this situation, we suggest increasing the rating of the output power or modifying the OLP point. The second one is the activation of over-temperature protection (OTP) when the internal temperature reaches the pre-set value. All of these conditions will let the switching power supply enter protection mode and shut down. After these conditions are removed, the switching power supply will be back to normal.
