Introduction LED Driver 1

Development of LED Drivers

First Generation

Fixed Output；

Input Voltage Range: 90-305Vac；

Basic protection：IP67+4KV Surge Protection。

Second Generation

Programmable：Output Current, Fixed Time Dimming, etc.

Intelligent Functions：3in1, Dali, etc.

Enhanced Protection：6KV surge protection and up.

Now, Third Generation

By Application：None-Isolated VS Isolated, Water-proof VS None Water-

Proof type;

By Area: 249Vac-528Vac, Class II, etc;

Best Protection: 10KV Surge Protection for Strictly Application

Better Design: Customized Products VS Standard Products.
