Agilent/Keysight 6201B DC Power Supply

The Agilent/Keysight 6201B is a 0-20 VDC, 0-1.5 A programmable DC power supply delivering 30 W maximum output. It operates in constant voltage and constant current modes, providing load and line regulation better than 0.01% + 4 mV (CV) and 0.03% + 250 µA (CC). Output ripple and noise measure less than 200 µVrms in CV mode and 500 µArms in CC mode, with transient recovery under 50 µs following full load current changes.

The supply features external voltage or resistance programming at 1000 ohms per ampere, high-speed programming to 30 V/ms, and fast 8-hour stability of 0.1% + 5 mV (CV) and 0.15% + 2.5 mA (CC). Internal impedance ranges from 0.02 ohms DC to 1 kHz, 0.5 ohms 1-100 kHz, and 3.0 ohms 100 kHz to 1 MHz. Temperature coefficient performance reaches 0.02% + 1 mV per °C (CV) and 0.02% + 1 mA per °C (CC).

Continuously acting constant current protection safeguards against all overloads and direct short-circuit conditions. Reverse polarity protection via integrated diode across output terminals prevents damage from miswiring. Operating temperature range spans 0°C to 50°C with storage capability to -40°C to +85°C.
