Products description

1400ma 40w constant current triac pwm LED driver


Our triac dimming led driver can help you add innovative lighting features to your design. Search for the best device for your system in two different ways: by the function of the LEDs in your design or by the topology of the LED driver power supply.SMARTS's LED power supply has a lower operating temperature than MOSO's 40w constant current power supply and is more adaptable to high-temperature working environments

  FAQ  


1. Do all of your enclosure power supplies have the voltage control dial to adjust voltage output (+/- 10%)?

Answer: Yes, these units have the voltage control dial to adjust voltage output (+/- 10%)

 

2. Do all of these units have protection from thermal overload (excessive heat), voltage overload, short circuit, and power surge?

Answers: Yes, all of those units have the protection  from thermal overload (excessive heat), voltage overload, short circuit, and power surge.

 

3. Do you have any enclosure power supplies with cooling fans?

Answer: Our 250w 320w 350w 400w 500w 600w enclosure power supplies are all have the cooling fan. May I know if you need also take 24v 250w models to test??
