Mechanical Specification
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 | 6 |
| 13A | 8 | |
| 16A | 9 | |
| 20A | 12 | |
| 25A | 15 | |
| 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 | 14 |
| 13A | 18 | |
| 16A | 22 | |
| 20A | 28 | |
| 25A | 35 | |
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 10%
Please try to use dimmers with power at least 1.5 times as the output power of the driver.
Derating Curve (output load vs TEMP.)
1. To extend their life, please refer to the Derating Curve and derate according to the temperature.
2. Please note that the rise in temperature of LED fixtures over a long period of time will cause their power to rise.
Therefore, we recommend the power supply to reserve a certain amount of load to avoid overloading.
