Notes |
1. All parameters if NOT specially mentioned are measured at 120VAC / 220VAC input , rated load and 25℃of ambient temperature. 2. To extend the driver's using life ,please reduce the loading at lower input voltage. 3.Loading should be 5-100%. |
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.
