Agilent/Keysight 6220B DC Power Supply

The Agilent/Keysight 6220B is a precision DC power supply engineered for benchtop laboratory and system integration environments. It delivers 0–20 V and 0–5 A with 100 W maximum output power, combining adjustable voltage and current control with exceptional load and line regulation. The unit features programming accuracy of ±(0.1% of setting + 10 mV) for voltage and ±(0.2% of setting + 5 mA) for current, backed by low ripple (≤1 mVrms) and fast transient response within 1 ms.

Adjustable overvoltage and overcurrent protection, remote sense compensation, and analog/digital control interfaces make it suitable for sensitive component characterization and power delivery validation.
