Agilent/Keysight E36313A

The Keysight E36313A is a 160 W triple-output programmable DC power supply engineered for benchtop applications demanding precise, stable power delivery. This unit combines three independent isolated outputs with exceptional regulation and low-noise performance, making it ideal for circuit design validation, component testing, and manufacturing environments. The E36313A delivers output ripple and noise below 350 µVrms / 2 mVpp with line and load regulation of 0.01%, ensuring the clean power conditioning required for sensitive analog and digital circuits.

Its intuitive 4.3-inch LCD color display, paired with individual voltage and current control knobs, enables rapid parameter adjustment without navigation delays. Remote control via USB, LAN (LXI Core), or optional GPIB interfaces supports both manual and automated test sequences. Advanced capabilities include LIST mode, output sequencing, tracking mode for channels 2 and 3, and 2-wire or 4-wire remote sensing.

Multiple protection layers - over-voltage, over-current, and over-temperature - safeguard against circuit faults and component failures.
