The HP 6200B Series is a family of four compact, completely transistorized bench DC power supplies covering a range of voltage and current combinations from low-current high-voltage to higher-current low-voltage applications. The series comprises the 6212B (0 to 100 Vdc at 0 to 0.1 A), the 6214B (0 to 10 Vdc at 0 to 1 A), the 6216B (0 to 25 Vdc at 0 to 0.4 A), and the 6218B (0 to 50 Vdc at 0 to 0.2 A). Each model is a well-regulated Constant Voltage/Constant Current supply that delivers full rated output voltage at the maximum rated output current, or can be continuously adjusted throughout the output range using concentric coarse and fine front-panel controls.

These supplies are intended for general electronics bench use, prototype development, component testing, and any application requiring a clean, adjustable DC source with both voltage-limit and current-limit operating modes. The front-panel CURRENT control establishes the output current limit when the supply operates as a constant voltage source, providing overload and short-circuit protection. The VOLTAGE controls establish the voltage ceiling when the supply operates as a constant current source. Automatic crossover between constant voltage and constant current modes occurs whenever the load conditions cause the preset limit in either mode to be exceeded.

Brand Heritage

The 6200B Series carries the Hewlett-Packard test and measurement legacy. HP's test and measurement business was spun out as Agilent Technologies in 1999, and Agilent's electronic measurement business was subsequently transferred to Keysight Technologies in 2014. Bench DC power supplies originally developed under the HP name continue in the Keysight catalog under successor product families, while the original HP units remain widely deployed in service.

Compare Other Models in This Series

The 6200B Series provides four discrete voltage/current combinations from a common bench platform, allowing the engineer to select the model that best matches the output range needed for a given application. The 6212B is the high-voltage, low-current member of the family at 0 to 100 Vdc and up to 0.1 A. The 6214B is the high-current, low-voltage member at 0 to 10 Vdc and up to 1 A. The 6216B and 6218B fall between those two extremes, with the 6216B providing 0 to 25 Vdc at up to 0.4 A and the 6218B providing 0 to 50 Vdc at up to 0.2 A.

Across all four models the chassis, cooling approach, control layout, meter, output terminal arrangement, ground-reference flexibility, and protection circuitry are common. The differences across the family are concentrated in the output voltage range, the output current capability, and the regulation and stability specifications that scale with the output rating of each model.

Each pre-owned model linked below is sold as its own dedicated product page with condition-matched pricing, condition documentation, and condition-appropriate options. Selection between the four models is driven by the output voltage and output current the device under test requires, not by tier or feature differentiation in the conventional sense.

The output voltage and current rating is the primary differentiator across the four models. Load regulation specifications scale with the output: less than 4 mV for a full-rating current change on the 6214B, 6216B, and 6218B, and less than 8 mV on the 6212B. Constant-current stability specifications also vary across the family, with drift specifications ranging from 1.3 mA on the 6212B to 15 mA on the 6214B. Ripple and noise specifications are common across the family at less than 200 microvolts RMS / 1 millivolt peak-to-peak in constant voltage operation, and less than 150 microamps peak-to-peak in constant current operation.

Beyond the output specifications, the four models share the same input power requirements, the same physical envelope, the same convection cooling, the same control set, the same meter functionality, and the same series/parallel operating capabilities. Refer to the comparison table that follows for the per-model output ranges and the per-model regulation, stability, and temperature-coefficient specifications drawn directly from the data section of this manual.
