How we test
Every supply is tested under resistive load at 25%, 50%, and 100% of rated current. We measure load regulation, ripple noise with an oscilloscope, and CV/CC transition accuracy.
Best under $100: KORAD KA3005P
The KA3005P earns our budget pick for one reason: programmable SCPI control at under $100 is genuinely rare. Load regulation is tight at moderate loads. Ripple is acceptable for digital work.

Best mid-range: Riden RD6018
The RD6018 covers ham radio and high-current bench work at 60V/18A. WiFi Modbus is the differentiator. Budget ~$60 for a Meanwell brick; the total system still undercuts commercial equivalents.
