SMUGDESK 8A Single-Channel AC-DC Rectifier Filter Board with LED

SKU CH-2YP3-SEA45

An 8 A single-channel AC-DC rectifier board with built-in LED indicator for stable DC power in audio and DIY circuits

  • 8 A single-channel output powers demanding audio and monitoring circuits
  • Built-in LED indicator shows power status at a glance
  • Integrated rectifier bridge and filter stage deliver stable DC with low ripple
  • Thickened PCB and quality components provide reliable heat dissipation
  • Suitable for DIY projects, amplifiers and experimental circuit power conversion

8A Single-Channel AC-DC Rectifier Filter Board

This single-channel board converts alternating current into filtered direct current at up to eight amperes. An on-board LED shows operating status at a glance. It is designed for hobbyists and technicians building or repairing linear power supplies.

Suited for audio amplifier

The module works well for DIY circuits, experimental setups and equipment that need steady low-ripple DC within the rated current. It is not intended for applications that exceed eight amperes, require multi-channel isolation or demand regulated voltage output beyond simple rectification and filtering.

LED indicator simplifies power verification

The built-in light lets you confirm the board is energised without a multimeter. Thickened PCB construction and quality components improve heat dissipation for sustained operation. No additional accessories, cables or software are included in the package.

Questions about this item

What AC voltage source do I need to connect to the board's input terminals?

Supply an AC voltage within the component ratings of the on-board rectifier bridge; the board then outputs filtered DC up to 8 A for your amplifier or monitoring circuit.

Can I keep my existing transformer and feed its AC secondary into this module?

Yes, connect the transformer's AC secondary wires to the board's AC input pads — the integrated bridge and filter will convert that AC to stable DC for the rest of your circuit.

How do I confirm the module is delivering DC power after wiring it up?

The built-in LED indicator lights when the board is powered and the rectified output is present, giving immediate visual confirmation of correct operation.
