Mechanical Specification
| 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 | 3 |
| 13A | 4 | |
| 16A | 6 | |
| 20A | 7 | |
| 25A | 9 | |
| 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 | 9 |
| 13A | 11 | |
| 16A | 14 | |
| 20A | 18 | |
| 25A | 22 | |
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 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 /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.
Using one dimming ---0-10/ 1-10V/ 10V PWM/ Potentiometer dimming
