277v 120v ul listed led driver 24vdc 30w dimmable led power supply waterproof
Efficiency > 84% / PF> 0.95, built-in PFC function, with PWM output dimming 24vdc 30w dimmable led power supply, will not change the color index, compliance to EN55015,EN61000-3-2 (≥60%load) EMC EMISSION, Compliance to EN61000-4-2,3,4,5,6,11, EN61547, light industry EMC IMMUNITY.
What is the dimming operation?
1) The Pulse-Width Modulation (PWM) of output voltage can be adjusted through input terminal of the AC phase line(L) by connection a phase/triac dimmer.
2) Usually matching with Forward phase , leading edge , Magnetic low voltage, triac dimmers, or Reverse phase, trailing edge ,Electric low voltage Dimmers.
3) lease try to use dimmers with power at least 1.5 times as the output power of the driver.
