Agilent/Keysight 6209B DC Power Supply

The Agilent/Keysight 6209B is a single-output DC power supply engineered for precision voltage regulation in laboratory and production test environments. Delivering up to 32 W across a 0–320 Vdc range with 0–0.1 A output current, this instrument combines stable output with fine-grain control and low noise performance. The 6209B accommodates benchtop operation or integrates into rack systems individually or in pairs, supporting series, parallel, and auto-parallel configurations for expanded voltage and current capability.

Key Features

• 10-turn voltage and current controls enable fine resolution adjustment and repeatability.


• Remote sensing compensates for lead losses in high-current applications.


• Low output impedance and sub-millivolt ripple suit sensitive analog and digital circuit development.


• Load regulation of 0.01% + 2 mV maintains output stability across load variations.

Typical Applications

• Component characterization and bench verification


• Equipment design and prototype validation


• Production test and burn-in operations


• Supply for precision measurement instruments

Compatibility & Integration The 6209B mounts individually on the benchtop or racks as a standalone unit or in pairs. Series, parallel, and auto-parallel operation allow users to combine multiple units for extended voltage or current ranges. Auto-tracking master/slave configurations enable synchronized operation. Front and rear panel terminals support both local and remote connections.
