TDA7293 Parallel Connection 255W Mono Power Amplifier Single Channel Assembled Board
Description:
- Voltage: DC +-30V 9A (Not exceed-45V)
-.Dimension: 117mm x 41mm
- Power: 255W MONO
- Speaker: 4 ohm or 8 ohm
- The amplifier board is used for fiber glass PCB, 1.6mm thickness.
-.It is completed soldered board.(same as Listing Photo)
- Package including: 1 x 255W TDA7293 Parallel 255W Mono Power Amp Board Kit
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!
