CA-233 Universal 32-60 inch LED LCD TV backlight constant current booster board 55-255V output constant current board original

Description:

1. Rectify the integrated power supply board for the positive side of the filter capacitor of the backlight to give the VCC voltage range between 45-165V.
2. Connect 12-24V voltage to VIN. Do not connect to high voltage VIN above 45V.
3. Power supply bottom line is connected to GND
4.NC is empty, not connected
5. Find the switch signal on the original power board and connect it to ON/OFF. The reference range is 2.5V-5V.
6. Connect the dimming signal of the original machine to the VADJ pin, 5V is the darkest, 0V is the brightest

If you do not know the voltage required for the backlight strip, please try the minimum current (default 200MA) when installing. If the backlight brightness is not enough, then slowly increase it. Do not use the maximum current to illuminate the backlight. It is easy to burn out the light strip or drive. board.

CA-233 current adjustment instructions:

J1=20MA

J2=40MA

J3=60MA

J4=J5=100MA

J6=200MA

The default output is 200MA. By short-circuiting the solder joint, the corresponding current value can be increased (added on the basis of 200mA). Be careful not to increase the excessive current to avoid burning the light bar.

About the input voltage: This constant current board requires 2 voltage inputs, VCC is connected to 40-165V voltage, VIN is connected to 12-24V voltage, and only one voltage is not boosted.

Since this product is a fragile product, (input and output reverse or output positive and negative will be damaged), once the use can not be sold twice, so the store products are only responsible for the warranty, do not accept returns. Please understand the instructions first, take care!

Tip: Pay attention to the insulation of the driver board. Do not immediately put it on the conductive object such as iron plate after power-on. After the power is turned on, pay attention to the discharge of 400V large electrolysis (to avoid electric shock or damage). In winter, the human body is very static. Do not touch the semiconductor on the circuit board directly (you can wash your hands and touch again).
