150~200W Constant Current Mode LED Driver

BLOCK DIAGRAM

PFC fosc : 50~120KHz

PWM fosc : 60~130KHz

DRIVING METHODS OF LED MODULE

※ This series works in constant current mode to directly drive the LEDs.

Typical output current normalized by rated current (%)

In the constant current region, the highest voltage at the output of the driver

depends on the configuration of the end systems.

Should there be any compatibility issues, please contact MEAN WELL.
