TEST OF CONSTANT CURRENT BOARD
PRODUCT DEMONSTRATION
Note: Adjust the current in short circuit ; Adjust the Voltage in open Circuit as shown in the figures above.
Test Method of Constant Current Driver Board
Testing situation:
The LED strip of backlight is on with the tester, but it does not work with the constant current board;
1. Cut off the power of TV, unplug the interface sockets of the constant current board and light bar;
2. Connect the constant current board with the tester using the cables in the kits on right polarity.
3. Insert the Red and Black pens of the tester into the anode and cathode of the interface of the LED light bar.
4. Turn the power of TV on.
5. Testing voltage ＞30V, Current ＞30mA and keep stable, and the LED strip working normal, then the Constant current board is normal.
