description: >
  Programmable triple-output DC power supply.
  Provides two fully adjustable channels (0–32 V, 0–3.2 A each),
  plus one fixed output channel selectable between 2.5 V, 3.3 V,
  or 5 V at up to 3.2 A. Supports independent, series, and parallel
  operation with total output power up to 220 W.
  Includes SCPI remote control via USB and front-panel save/recall
  of setup states.
