All parameters NOT specially mentioned are measured at rated load for 120VAC and 25℃of ambient temperature. 2. Derated output is required at low input voltage to ensure long service life. [Custom Product Tab] MCB recommendation When the input voltage is 120Vac, the number of LED Driver matched by circuit breakers is as follows: MCB Type Level The number of LED Driver B type 10A 66 13A 86 16A 105 20A 132 When the input voltage is 277Vac, the number of LED Driver matched by circuit breakers is as follows: MCB Type Level The number of LED Driver B type 10A 125 13A 163 16A 200 20A 250 When the input voltage is 120Vac, the number of LED Driver matched by circuit breakers is as follows: MCB Type Level The number of LED Driver C type 10A 66 13A 86 16A 105 20A 132 When the input voltage is 277Vac, the number of LED Driver matched by circuit breakers is as follows: MCB Type Level The number of LED Driver C type 10A 140 13A 183 16A 225 20A 281 Note： 1. The above quantities of the led drivers connected on the Type C is recommended base on the maximum ambient temperature is 50 °C. 2. The breaker should be selected according to the input rated voltage, input rated current, ambient temperature, and trip characteristic curve. American wire gauge Input wire 1015 2*18 AWG 0.824mm2\Black(L),White(N) Output wire 1015 2*22 AWG 0.326mm2\Red(V+),Black(V-) Dimming electroni wire 1015 2*22 AWG 0.326mm2\Purple(DIM+),Pink(DIM-) Dimming Operation and Connecting Diagram Using two ways of dimming at the same time, you must be assured that LED lighting is up to the max. Brightness then you could operate with the other dimming; Using one dimming ---TRIAC/Phase cut dimming 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 or lighting system. 2. Working with Forward phase, MLV and Reverse phase, ELV, TRIAC dimmers or light system. 3. Min. loading is about 10% 4. Please try to use dimmers with power at least 2 times as the output power of the driver. Using one dimming ---0-10/ 1-10V/ 10V PWM/ Potentiometer dimming [/Custom Product Tab]
