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] 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. ■ Mechanical Specification American wire gauge Input wire Black(L) White(N) (2*18AWG) Output wire Red(V+) Black(V-) (2*22AWG) ■ Dimming Operation and Connecting Diagram 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 /leading edge, MLV and Reverse phase /trailing edge, ELV, TRIAC dimmers or light system. 3. Min. loading is about 10% 4. Please try to use dimmers with power at least 1.5 times as the output power of the driver. [/Custom Product Tab]
