CA-901 General Power Module for LCD TV Switching Power Supply

Main features of THE CA-901 REV: 02 module:

1. Adopt DC sampling to drink TL431 voltage stabilizing feedback, so that it has good voltage stabilizing performance.

2. This module adopts 12V/24 selective output, only need to link the corresponding pad, can output 12V or 24V.

3. Reasonable design, easy to install (as shown below). Just connect the pads according to the required output voltage according to the diagram. (the default power module is 24V.)

4. General LED TV under 46 inches

5. Input: 12V/24V selective output

Installation Instructions

1. Remove the original power switch tube or thick module, and fix the module firmly to the original heat sink.

2. Check whether the reverse peak absorption loop is normal and whether the secondary load of the transformer is short-circuited;

3. Connect the red line of the module to the welding spot of the cpole of the original power switch tube (the field-effect tube is the D-pole, and the thick mode is the C-pole of the internal power tube);

4. Connect the black wire in the hot area (the negative pole of the filter capacitor of large power supply);

5. Yellow wire is connected to the positive pole (main power supply) of the filter capacitor of the main power supply (12V or 24V) at the negative pole of the secondary rectifier diode of the transformer.

6. White wire is connected to the negative pole (cold end) of the filter capacitor of the transformer secondary pole main power supply (12V or 24V);

7. Connect the green wire to the supply section of the original module IC (9V-18V), and disconnect the power end of the original machine IC from the circuit.

8. Select the corresponding pad according to the output voltage, as shown below;

9. After connecting the line, we suggest: disconnect the line (unplug the main power plug) load, connect to the false load (10 20 watts resistance), measure the voltage, check the error before electing the test machine.
