UL Waterproof 277VAC 12VDC Dimmable LED Power Supply

  Dimming Operation for 277v power supply waterproof  

- Output constant current level can be adjusted through input terminal of the AC phase line(L) by connection a triac dimmer.

- The Pulse-Width Modulation (PWM) of output voltage can be adjusted by the input terminal of the AC phase line(L) by connection a phase/triac dimmer.

- Compatible with Forward phase, leading edge, Magnetic low voltage, triac dimmers, or Reverse phase, trailing edge ,Electric low voltage Dimmers.  

- please try to use the small power dimmers with power at least 1.5 times as the output power of the driver., which can be accessed to a wider dimming range, high-power dimmer is difficult to achieve the output current to zero.
