The Keithley 2260B-250-13 is a 1080W programmable DC power supply engineered for benchtop and system-level applications demanding precise voltage and current control. This single-output instrument delivers 0–250V and 0–13.5A with programmable rise/fall times, constant current priority mode, and simulated battery output characteristics via adjustable internal resistance. Fast 1ms transient response and comprehensive protection (OVP, OCP, OTP) make it suitable for component testing, production validation, and design verification across research, quality control, and manufacturing environments. The unit accommodates both analog control via 26-pin connector and digital interfaces for laboratory and automated test system integration.
