Agilent/Keysight 6217A DC Power Supply

The Agilent/Keysight 6217A is a fully transistorized DC power supply delivering constant voltage with current-limiting protection. Designed for bench or relay rack operation, It has stable, adjustable output from 0–50 VDC at 0–200 mA with load and line regulation better than 4 mV. The unit includes fixed current-limit protection adjustable internally, guarding against overloads and short circuits.

Output can be grounded at either terminal or floated to 300 V off ground, enabling flexible circuit configurations. A single front-panel meter with range selector displays either voltage or current in real time.
