DESCRIPTION

UTC UL75 can drive a plurality of LED strings. When the

voltage detecting circuit detects the different voltage level of input

voltage, it can control the LED strings. If the input voltage is lower

that it will bypass some LED strings. And turn on all LED strings

when the input voltage is higher. The number of LEDs in LED array

is dependent on the voltage level of the AC power source, That

includes of ±10% variations.

UTC UL75 is an ideal solution for LED Lamps (e.g. E27,

GU10), General Illumination, LED Strings (e.g. T-8 Tube) and

Constant Current Sink.
