Keithley 2260B-30-108 – Programmable DC Power Supply, 30V, 108A, 1080W

The Keithley 2260B-30-108 is a 1080 W programmable DC power supply delivering 30 V at 108 A for precision testing applications. This single-output instrument combines low noise performance with independent control of voltage and current ramp rates, making it suitable for R&D, quality assurance, and production test environments where load transients and dynamic power demands require rapid response. The supply accepts 85–265 VAC single-phase input and maintains 0.97–0.99 power factor efficiency. Output voltage regulation is 18 mV line regulation and 20 mV load regulation in constant voltage mode, with ripple and noise held to 14 mV RMS across the full output range. Current ripple measures 72 mA RMS. Fast transient recovery - 1 ms to step load changes - supports testing of sensitive components. Temperature drift is specified at 200 ppm/°C after warmup.
