- 1
Voltage and current
Add up the maximum voltage and current you need, then add some headroom. A supply working near its limit runs hot and has less margin.
- 2
Linear or SMPS
Linear supplies have very low noise, which suits sensitive analog work. SMPS models are lighter and more efficient, which suits higher power.

Programmable and PC interface
If you run repeatable tests, look for a model you can control from a PC.
