Pros & Cons

Pros

  • ✓ 150W output (0-30V, 5A) with fine 0.01V / 0.001A resolution
  • ✓ Ripple rated under 20mV for sensitive analog and MCU bench work
  • ✓ PC programmable with 6 presettable voltage/current parameter groups
  • ✓ 2.8-inch IPS screen flips 90 degrees, shows numeric and curve views
  • ✓ Accepts PC, QC, and DC input sources, so USB-PD bricks work

Cons

  • ✗ 30V/5A ceiling rules out higher-voltage amp or tube projects
  • ✗ No bundled input adapter listed, so you supply the QC or DC source
  • ✗ Switching topology, not linear, so lowest-noise audio work may still object
