The Agilent/Keysight 6228B is a dual-output DC power supply delivering 100 W total across two independently adjustable 50 W channels. Each output spans 0–50 V and 0–1 A, with constant voltage and constant current modes plus integrated overvoltage protection crowbars. The supply operates in independent, auto-series, auto-parallel, or auto-tracking configurations, enabling flexible circuit powering from single-rail to matched ±V topologies.
Technical Specifications
Output Characteristics

• Weight: 11 kg
• Half-rack width form factor
– Key Features
• Auto-Series Mode: Delivers up to 100 V from a single output
• Auto-Parallel Mode: Delivers up to 2 A from a single output
• Auto-Tracking Operation: Right output tracks left output within 0.2% ±2 mV; ideal for matched positive and negative supplies
• Overvoltage Protection: Independent crowbars on each supply; in tracking mode, an overvoltage event in one supply trips both
• Dual-Mode Operation: Simultaneous constant voltage and constant current control
– Typical Applications
Optimized for operational amplifier circuit development, matched-rail analog designs, and general-purpose laboratory testing requiring precision DC power with multiple voltage and current configurations.
– Compatibility & Integration
Front panel controls support mode selection and voltage/current adjustment. Class I safety compliance with protective earth grounding required.
