Description The rectifier filter board uses a large current 25A rectifier bridge, full-wave rectification of the dual AC into dual DC, using four large capacitors of 3300uf/25V as filtering, 104 monolithic capacitors as decoupling, effectively suppressing AC clutter, making the output The DC power is purer. As a power amplifier dual power supply, it can be used in medium-low power amplifiers such as LM1875, TDA2030, TDA7294, and LM3886. Parameter Product Name: Dual power rectifier filter board； Input voltage: dual AC 9-17V; Output voltage: dual DC DC ± 12-24V; Flat Bridge Power Supply: 25A; PCB size: 67x38mm; PCB material: FR-4 full glass fiber board 1.6mm thick; Size: 67x38x28mm (LWH); Installation hole distance: 60x31mm, hole distance: 3.2mm; NOTE: This board is equipped with an electrolytic capacitor with a withstand voltage of 25V. The maximum output DC voltage cannot exceed 25V. After 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 must replace the filter capacitor with a higher voltage. For example, when replacing an electrolytic capacitor with a withstand voltage of 50V, the maximum output DC voltage can reach 50V, and the maximum input AC voltage can reach 35V. Overvoltage operation will cause the electrolytic capacitor to bulge or burst. Weight: 45g. Package Included: 1pcs 25A Dual Power Rectifier Filter Board.

The so-called low-pass filter plate is to filter the human voice more than treble part, retain the low frequency part is amplified to improve the bass reproduction efforts will not hear the human voice and high-frequency sound when playing the instrument. The buyer must understand this knowledge, in order to avoid the only, do not know how to use. Most of the market before the subwoofer preamp board are basically dual power, the majority of DIY enthusiasts, is not very convenient to use, after all, a single power supply is relatively easy to find, the premise of guaranteeing effective, we have introduced a single-supply subwoofer home board, you can share a stage with the power amplifier boards, DIY is very convenient.
