dimming operation
- The Pulse-Width modulation (PWM) of output voltage can be adjusted through input terminal of the ac phase line(L) by connection a triac dimmer.
- usually matching with leading edge Triac Dimmers( can customized as a driver only matching trailing edge Triac dimmers if needed).
- please try to use dimmers with power at least 2.5 times as the output power of the driver.
- for forward phase,Magnetic low voltage and Triac dimmers
warning
- prevent to reverse polarity;
- risk of electric Shock. When used outdoors, install only on a circuit protected by a class a GFCI;
- risk of Fire. installation involves special wiring methods to run wiring through a building structure. consult a qualified electrician;
- risk of electric Shock. mount the unit at a height greater than 1 foot from the ground surface.
derating curve
- To extend their life, please refer to the derating curve and derate according to the temperature
