PW28 Dual Power Filter Rectifier Board, HighCurrent 25A Flat Bridge Unregulated Power Supply Board, AC to DC DualOutput Rectifier Filter Module for Audio Power Amplifier DIY Electronic Build Project

The PW28 dual power filter rectifier board is an unregulated power supply module built with highcurrent 25A flat bridge rectifier chip, designed for audio power amplifier DIY projects. It takes AC alternatingcurrent input from power transformer and outputs symmetrical dualrail unregulated DC power, providing clean power supply for analog audio amplifier circuits. Thickened copper traces on PCB handle large operating current effectively, reducing heat generation and voltage drop during highpower working status. This module combines rectification and filtering functions, simplifying your powersupply circuit construction for amplifiers. It is widely applied for HiFi audio amplifier assembly, old audio equipment repair and various dualvoltage DIY electronic experiments. Please match proper AC transformer input voltage according to your amplifier circuit requirements. Pay attention to heat dissipation for flatbridge component under heavyload working condition, avoid shortcircuit on output terminals to prevent board burnout.
