The Keithley 2200-72-1 is a single-channel, programmable DC power supply delivering 0V to 72V at up to 1.2A with 86W total output. This linear supply combines low-noise performance with high measurement accuracy, making it suitable for component testing, circuit development, and automated test environments. Voltage setting accuracy reaches ±0.03% + 6mV under remote sensing at 25°C ± 5°C, while current setting accuracy is ±0.05% + 1mA. Output ripple and noise remain below 1 mVRMS and 3 mVp-p across the 20 Hz to 7 MHz band.
Technical Specifications
Output voltage spans 0V to 72V with 1 mV resolution; output current ranges 0A to 1.2A with 0.1 mA resolution. Voltage readback accuracy is ±0.02% + 5mV, and current readback accuracy is ±0.05% + 1mA. Load regulation maintains less than 0.01% + 2mV for voltage and less than 0.05% + 0.5mA for current. Line regulation is below 0.01% + 1mV (voltage) and below 0.05% + 0.1mA (current). Current ripple and noise remain under 3 mARMS. The unit accepts 99–132 VAC at 110V AC setting or 198–264 VAC at 220V AC setting, both at 50/60Hz input frequency. Power consumption is 250VA.
