Pros & Cons
Pros
- ✓ 0-30V / 0-5A range with coarse and fine knobs, 10mV / 1mA setup resolution
- ✓ Ripple rated at 2mV rms and 3mA rms for linear-supply noise floor
- ✓ USB port with included cable and software for PC remote control and data logging
- ✓ Built-in memory presets recall frequently used voltage and current settings
- ✓ Over Current Protection auto-shutoff, thermo-sensor fan, insulated sockets, CE certified
Cons
- ✗ Bundled control software is Windows-only, no macOS or Linux support
- ✗ 110V/60Hz input only, so no direct use on 220V mains
- ✗ Single output rail means no second channel for split-supply bench work
- ✗ 5A ceiling limits it on higher-draw loads like vintage AT boards or amp stages
