CE ROHS listed 240 volt led power supply 40w for led tape
Many triac dimmable LED drivers work by varying the amplitude of current being delivered to the LEDs. If you are using more than one power supply to power multiple LED strips, then the load on each driver must be matched as closely as possible to each other in order to keep the dimming synchronised.

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.
