Keithley 2268-80-10 850 Watt DC Power Supply

The Keithley 2268-80-10 is a single-channel, 850 W DC power supply engineered for high-power testing applications requiring stable, clean output with exceptional regulation and low noise. It delivers programmable voltage (0 V to 80 V) and current (0 A to 10 A) with ±0.1% voltage accuracy and ±0.2% current accuracy. Control options include an intuitive front-panel LCD interface with rotary encoder and tactile buttons, or remote operation via GPIB, USB 2.0, and LAN (10/100Base-T Ethernet). All remote interfaces support SCPI command protocol. Output ripple and noise remain below 5 mV peak-to-peak, with line regulation of ≤0.01% and load regulation of ≤0.05% for voltage. Transient response time is ≤500 µs for 50% to 100% load changes. Integrated protection includes user-selectable overvoltage protection (OVP) and overcurrent protection (OCP) limits, plus internal over-temperature protection (OTP). Output stability reaches ≤0.01% per hour. The instrument supports programmable output on/off control and real-time voltage, current, and status monitoring via the display. This single-output design is suited for industrial test environments, research applications, and equipment development requiring precise high-power DC delivery.
