Dual Power Supply Module for Audio Amplifiers
SKU 7100-FT1764KEAN 8219671081511Item type: Assembled, KitBench power supplies
Description
| This dual power supply module is designed to deliver a symmetrical DC voltage from a transformer with a dual AC output. It is particularly suited to powering high-power audio output stages.
It uses a 25 A bridge rectifier and a bank of four 4700 µF / 63 V electrolytic capacitors for effective filtering of the rectified voltage. For correct and safe operation you must use a transformer with two secondary outputs rated no higher than 36Vac with a centre tap. This value keeps the voltage across the capacitors within safe limits, avoiding any risk of overvoltage and ensuring long-term reliability. The module is easy to assemble, compact and rugged, ideal for audio applications that call for a stable, well-filtered symmetrical supply. Important note: the transformer is not included and must be purchased separately. Soldering is required for assembly. The kit is supplied complete with instructions.
