Buying Guide
Key considerations to help you choose the right programmable power supply with USB:
- Output range and resolution: Look for units that offer at least 0-30V and 0-10A with 10mV / 1mA resolution for precise adjustments.
- Control interface: USB or USB-C PC control enables automation and data logging; consider whether Modbus or software presets are important for your workflow.
- Display type: Four-digit or color LCD readouts improve quick verification of set vs. actual values; dual displays help when monitoring multiple parameters.
- Safety protections: Overvoltage, overcurrent, overheating, and short-circuit protection are essential for protecting both the supply and the load.
- Programmable memory: Preset channels and waveform outputs streamline testing with repeatable results.
- Size and weight: For lab benches with limited space, a compact form factor is advantageous.
- USB charging capability: If you need simultaneous device charging, ensure the unit provides a robust USB-C or USB-A port with adequate wattage.
