Keithley 2260B-80-27 – Programmable DC Power Supply, 80V, 27A, 720W

The Keithley 2260B-80-27 is a programmable DC power supply engineered for R&D, quality control, and production test environments that demand precise voltage and current control. Operating at 80V, 27A, and 720W, it integrates into automated test systems where speed and flexibility drive test cycle efficiency. The unit delivers ±0.5% voltage accuracy and ±1% current accuracy, with a rapid 1 ms transient recovery time to load changes.

Fast discharge capability and programmable rise/fall times (0.1 V/s to 160 V/s for voltage; 0.01 A/s to 144 A/s for current) protect sensitive loads from inrush damage and enable dynamic load testing.
