Keithley 2260B-800-2 – Programmable DC Power Supply, 800V, 2.88A, 720W

The Keithley 2260B-800-2 is a programmable DC power supply delivering up to 800 V and 2.88 A across a 720 W output range. Built for high-voltage test environments, it provides precise voltage and current control with line regulation to ≤0.01% + 3 mV and load regulation to ≤0.02% + 5 mV. Output ripple and noise remain below 5 mVrms and 50 mVp-p across the 20 Hz to 20 MHz spectrum. The supply incorporates overvoltage, overcurrent, overpower, and reverse polarity protection. Programming accuracy reaches ≤0.1% + 10 mV for voltage and ≤0.1% + 10 mA for current at 25°C ±5°C. Transient response settles within 1% of setpoint within 500 µs following a 50% load change.
