Notes |
1. All parameters NOT specially mentioned are measured at 110V/230VAC input , rated load and 25℃of ambient temperature. 2. Ripple& noise are measured at 20MHz of bandwidth by using a 12”twisted pair-wire terminated with a 0.1uf &47uf parallel capacitor. 3. Tolerance:includes set us tolerance,line regulation and load regulation . |

FAQ
1. What is class 2 standard?
Answer: the requirements of class 2 are :1. less than or equal to 5A 2. less than 100w. And should satisfied with these two conditions at the same time.
2.Can we make the 120w 150w 200w 250w constant volatge led drivers into one output?
Answer: Yes.
3. If all dimmable LED drivers we ordered will provide more than 12 or 24 volts? As our some of LED lighting 's voltage is more than 24VDC a bit .
Answer: ±0.5% is the acceptable margin of error for both 12v dc and 24vdc led drivers.
