Notes |
1. All parameters if NOT specially mentioned are measured at 110VAC / 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%. |

Mechanical Specification
- Input (L) and (N) with wires to be connected AC.
- Output LED SEC :(LED+) (LED-)
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
