20W 350~700mA Triac 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. Built-in active PFC function

4. Class Ⅱ power supply. Full protective plastic housing

5. Dimming effect smooth, no flicker

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

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