Notes

1. All parameters if NOT specially mentioned are measured at 120VAC input, rated load and 25℃ of ambient temperature.

2. To extend the driver's using life ,please reduce the loading at lower input voltage.


Feature

Flicker-free

Cooling by free air convection 

Suitable for LED lighting and moving sign applications 


Triac dimming method matching problems troublesome! The triac power supply module made by most manufacturers has poor linearity, dimming is not smooth and there is beating! Also flashing!

ottima triac dimming power supply has been exported to foreign countries for many years, and its linearity and compatible performance are at the international high-end level; there are no unmatched dimmers and lighting control systems in Europe and the Americas, which can solve the problem of node flicker and controller trouble!

FAQ

1.Can i get the full price list of your led driver?

Because there are many kinds of our led driver, in order to supply you the quite right led driver you need and save your time, we would like to have your spec requirement in details, then we will recommend you the suitable led driver and quote good price for you. 

2. What transformer you use?

All of our coils are use pure copper wire

3.How about your PCB board?

We use double glass fiber board(FR-4) with good heat dissipation effect
