2. The product can effectively inhibit AC clutter, making the output DC more pure, as a dual power supply for amplifiers, can be used for LM1875, TDA2030, TDA7294, LM3886 and other low-power amplifiers
3.The PCB board is made of FR-4 fiberglass board, and the large-area copper pavement obtains small internal resistance of the power supply.
4. The rectifier filter board uses a 25A rectifier bridge with high current to rectify the dual AC full wave into dual DC, and four 3300uf/25V capacitors are used for filtering, with a total capacity of up to 13000uf.
5. High-current input and output terminals using KF301-3P terminals, wiring fast and easy to add another 2.0mm-2P power output terminals, so that DIY is more practical!
Product Name: Dual Power Rectifier Filter Board
Input Voltage: Dual AC9~17V
Output Voltage: Dual DC DC±12~24V
Flat bridge current: 25A
PCB material: 1.6mm thick FR-4 full glass fiber board
Mounting hole spacing: 60x31mm, hole diameter: 3.2mm
This board is equipped with 25V electrolytic capacitors, the maximum output DC voltage can not exceed 25V, the full-bridge rectifier filter has about 1.4 times the boost, so the input AC voltage can not exceed 17V. if you need a higher voltage, you have to replace the filtering capacitors with higher withstand voltage. If you need higher voltage, you have to replace the filter capacitor with higher voltage, for example, if you replace it with 50V electrolytic capacitor, the maximum output DC voltage can be up to 50V, and the maximum input AC voltage can be up to 35V. over-voltage work will make the electrolytic capacitor bulging or bursting!
