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 |
| C type | 10A | 1 |
| 13A | 2 | |
| 16A | 3 | |
| 20A | 3 | |
| 25A | 4 | |
| 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 | 4 |
| 13A | 5 | |
| 16A | 6 | |
| 20A | 8 | |
| 25A | 10 | |
Note：
1. The above quantities of the led drivers connected on the Type C is recommended base on the maximum ambient temperature is 50 ℃.
2. The breaker should be selected according to the input rated voltage, input rated current, ambient temperature, and trip characteristic curve.
Dimming Operation
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 20%
4.Please try to use dimmers with power at least 1.5 times as the output power of the driver.
