ITEM NAME:2x TV Backlight Driver Step UP Module LED Constant Current Description: LED LCD TV Constant Current Backlight Inverter Driver Board Boost Step-Up Module. Suitable for 65 inch and smaller LCD TV, universal for all brands and models. Input Voltage: 10-28V; Output Voltage: 8-165V; Default Output Current: 248mA (adjustable max. to 650mA; for voltage step-, support max. 500mA) The 10-28V power supply corresponds to 8-165V output automatic adaptation. When output voltage is lower than input voltage, it is step- mode; vice versa. The boost type should not exceed 40W. The best control is within 32W. The output current of the step-type must not exceed 500 mA (very critical). Full-bridge drive, full-bridge rectification, greatly reducing overall circuit ripple. High power efficiency, low failure rate. Specification: Size: 110x50x10mm / 4.33x1.97x0.39inch Package Includes: 2 Piece LED TV Constant Current Board Note: Please allow slightly measuring deviation due to manual measurement.
