China constant current 1050ma intertek led power supply
Constant current intertek dimmable led driver maintain a fixed output current (mA) which is usually measures in milliamps (mA) or amps (A) and within a specified range of voltages. A Constant current LED Power Supply works by varying the voltage along an electronic circuit and thus allows the current to remain constant throughout the LED system.

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 .

Dimming Operation
1. Output constant current level can be adjusted through input terminal of the AC phase line(L) by connection a triac dimmer.
2. Compatible with Leading edge or tailing edge triac dimmers.
3. please try to use the small power dimmers, which can be accessed to a wider dimming range, high-power dimmer is difficult to achieve the output current to zero.

FAQ
1. I tested the magnitude magnetic driver and it runs the LEDs to hot. Does the one you offer run the LEDs like a switching power source and is dimable with a triac dimmer?
Answer: Yes, all our led drivers run the leds like switching power source and this led driver you've mentioned is triac dimmable type, it should be dimmable with a triac dimmer.
2.What is UL annual fees?
Answer: UL annual fees will be charged by UL for once time each year. Its funtion is maintaining cost for the online UL file.
Actually, it's necessary for you to pay UL multiple listee cost and UL annual fees to UL if you would like to do UL multiple listing. And all the cost would be charged by UL directly.
3.Do these(vt) buzz working with forward edge dimming?
Answer: Actually, we sugguest that our customers usel with forward edge triac dimmer for our 100-130vac VT series. And they work well with forward edge triac dimmer.
Most importantly, there is almost no any buzz during they work with forward edge triac dimmer.
4. What is the shipping way do you have?
Answer:
--By air, by sea.
