Multi-Output DC Power Module

Create several positive and negative supply rails from one suitable DC input. This compact power module is intended for electronics experiments that need more than a single supply voltage.

✅ Power circuits that need positive and negative rails - The module provides +12V, -12V, +5V, -5V and +3.3V outputs.

✅ Use one input for several supply voltages - A compatible 5-24V DC source feeds the board instead of requiring a separate input supply for each rail.

Plan the Rails Around the Circuit

An experimental circuit may need a negative rail for one stage and a lower positive voltage for another. Identify those requirements first, then connect each part to the correct output and reference point before applying power.

Size the input supply for the combined output demand and follow the module's thermal limits. The available current depends on the rail and operating conditions; do not treat a per-channel figure as a promise that every output can deliver it simultaneously.

Technical details

• Input: 5-24V DC
• Outputs: +12V, -12V, +5V, -5V, +3.3V
• PCB approx. 100 x 51mm
• Total output must not exceed 10W; observe lower thermal limits
• Electronics module, not an enclosed mains power supply

Check the circuit's voltage and current needs, then build a suitable multi-rail supply.
