Product Description
YJ 255W TDA7293 X 3pcs Mono Amplifier board new

Voltage: DC+ - 30V 9A

PCB size: 117 * 41MM

Note:

Not exceed-45V supply voltage, and we must ensure that - the power supply voltage and symmetry, the higher the IC supply more heat, the greater the required heat sink;

Metal parts of the IC can not be connected with the heat sink, IC, and to have the insulation sheet between the heat sink and thermal grease to be evenly coated with the installed radiator must use the multimeter to measure whether the IC and radiator conduction;

TDA7293 positive and negative power supply terminal to the same time, the voltage must not be added to a group, add the other way, or IC die. Positive and negative power supply suddenly of a fuse to blow, can also cause power asymmetry, IC will be burned. If an IC is damaged teeth, can also cause other asymmetric channel IC power supply, and will lead to other normal IC burn! Special attention to the power supply capacitors to discharge before the board and the amplifier board connectors, - not very connected to the corresponding counter, IC metal parts can not be grounded, burn IC does not warranty!
