Keithley 2260B-30-36 – Programmable DC Power Supply, 30V, 36A, 360W

The Keithley 2260B-30-36 is a programmable DC power supply delivering up to 30V and 36A with 360W maximum output power. It has precise voltage and current control with programmable rise and fall times, protecting low-impedance loads from inrush current damage and eliminating overshoot in LED applications. The unit simulates battery characteristics through programmable internal resistance and supports constant current priority mode to minimize transient overshoot.
