20W 350~700mA Phase-cut Constant Current Driver PUP20T-1LMC

PUP20T-1LMC is a constant current output mode LED driver.The output current can be easily set via DIP switch.The driver supports leading edge (Triac) and trailing edge (ELV) dimmer, achieve a smooth dimming effect.


1. Single channel output, output current level selectable by DIP S.W.

2. Support Leading edge (Triac) and Trailing edge (ELV) dimmer

3. Dimming Voltage 120VAC

4. Built-in active PFC function

5. Class 2 power supply. Full protective plastic housing

6. Dimming effect smooth, no flicker

7. Protections: Short circuit, over load, over voltage

8. Suitable for indoor LED lighting application,such as down light,spotlights,panel light,and so on
