Universal TransformerFree AC-DC Constant Current LED Driver
14.09.2007
Zywyn Corporation introduced ZD832, the universal TransformerFreeTM AC-DC constant current LED driver for the industrial lighting and display lighting market
The ZD832 is a high voltage, AC-DC constant current driver for driving a string of white or RGB LEDs in series without the use of external transformer and no bridge rectifi er.
It operates from a direct input voltage of 85VAC to 170VAC or 170VAC to 240VAC off the AC mains and generates a programmable constant output current of up to 30mA by a single resistor.
The ZD832 also features digital PWM and analogue dimming control with over-temperature protection and over-voltage limiting functions. With high voltage isolation supported by the robust proprietary processing technology, there is no EMI generation and it does not require any additional EMI filtering circuits.
