Agilent/Keysight E36233A

The Keysight E36233A is a 400 W dual-output DC power supply built for electronic testing, development, and precision measurement applications. Each output delivers 0–30 V at 0–20 A (200 W per channel) with autoranging capability. The instrument supports auto-parallel configuration for up to 40 A output and auto-series operation for voltages up to 120 V.

Programming and readback accuracy of ±0.03% + 4 mV (voltage) and ±0.1% + 6 mA (current) enable consistent, repeatable results. Line and load regulation better than 0.01% with ripple and noise below 350 µVrms ensure clean power delivery. Remote 4-wire sensing improves accuracy for sensitive circuits.
