Keysight (Agilent) E36233A 400W Autoranging Dual Output Power Supply, 30V, 20A

The Keysight E36233A is a 400 W dual-output DC power supply engineered for demanding benchtop test and measurement applications. Each of its two independent outputs delivers up to 30 V and 20 A (200 W per channel), with autoranging capability that maximizes available current across all voltage settings. Outputs can be combined in auto-parallel mode for up to 40 A total current, or in auto-series mode for up to 60 V total voltage. The supply features exceptionally low noise—less than 350 µVrms across the 20 Hz to 10 MHz band—and maintains 0.01% line and load regulation. Programming accuracy reaches 0.03% + 4 mV for voltage and 0.1% + 6 mA for current, with matching readback accuracy. Over-voltage, over-current, and over-temperature protection safeguard connected devices. A 4.3-inch LCD color display provides real-time monitoring, while variable slew rate control, data logging, output sequencing, and LIST mode support complex test routines. The unit accepts both local 2-wire and remote 4-wire measurements.
