Agilent/Keysight 6212B DC Power Supply

The Agilent/Keysight 6212B is a discontinued DC power supply designed for laboratory testing and measurement applications requiring stable, adjustable voltage and current output. Built on the proven 6000 series platform, this unit delivers up to 100 V and 0.1 A with 10 W total power output, supported by exceptional line and load regulation of better than 0.01% + 4 mV. The supply features two 3½-digit displays for continuous monitoring of voltage and current levels, front-panel controls for output adjustment and overvoltage protection (OVP) programming, and LED state indicators.

Autoranging topology using 20 kHz pulse-width modulation with power MOSFETs enables full output power across a wider voltage-current combination than conventional designs. Internal impedance remains below 0.02 Ω from DC to 1 kHz, ensuring low source impedance for precision load testing.
