Keithley Series 2200 USB/GPIB DC Power Supplies

The Keithley Series 2200 is a single-channel programmable DC power supply engineered for automated test environments requiring precise voltage and current delivery. Each unit integrates USB and GPIB interfaces for seamless control in mixed-protocol test systems. The Series 2200 delivers stable DC power across multiple voltage and current configurations, supporting both constant voltage and constant current operation modes.

Technical Specifications

Output voltage ranges span 0–20 V, 0–30 V, 0–32 V, 0–60 V, and 0–72 V depending on model selection. Current outputs vary by configuration, with examples including 0–2.5 A and 0–5 A ratings. Maximum power output ranges from 86 W to 150 W across the series. Voltage output accuracy is ±0.03% with a 1 mV setting resolution. Current output accuracy reaches ±0.05%. Readback accuracy is ±0.02% for voltage and ±0.05% for current, with current measurement resolution of 0.1 mA. Voltage ripple and noise measure <5 mVp-p, <1 mV RMS, and <3 mV peak-to-peak. Load regulation holds <0.01% + 2 mV for voltage and <0.05% + 0.1 mA for current. Line regulation maintains <0.01% + 1 mV (voltage) and <0.05% + 0.1 mA (current). Response time for setting changes is 35 ms rising and 35 ms falling. Input accepts selectable 110 VAC (99–132 VRMS) or 220 VAC (198–264 VRMS) at 50/60 Hz. Power consumption ranges from 250 VA to 350 VA depending on model.
