Keysight (Agilent) E36234A 400W Autoranging Dual Output Power Supply, 60V, 10A

The Keysight E36234A is a 400 W dual-output DC power supply with autoranging technology, delivering 60 V and 10 A per output. Each output independently provides up to 200 W with exceptional voltage and current accuracy. Autoranging automatically supplies the highest current available at any given output voltage, streamlining test configuration and reducing programming overhead.

The E36234A supports series operation for doubled voltage output (120 V maximum) and parallel operation for doubled current output (40 A maximum), enabling flexible power architectures across multiple test scenarios. Voltage programming accuracy reaches ± (0.03% of output + 8 mV), while current accuracy is ± (0.1% of output + 3 mA). Line and load regulation better than 0.01% ensures stable power delivery under varying load conditions.

Output ripple and noise remain exceptionally low: voltage noise measures less than 350 µVrms (20 Hz to 10 MHz), and current noise stays below 1 mA rms. Adjustable voltage slew rate control spans from 50 ms to 20,000 seconds for 0-to-max transitions, critical for sensitive device characterization. Programming settling time is 50 ms.

Comprehensive protection includes overvoltage (OVP), overcurrent (OCP), and over-temperature (OTP) functions. Local 2-wire or remote 4-wire sensing capability, selectable via internal relays, enables precision voltage regulation at the load terminals. Data logging captures measurements at intervals from 200 ms to 60 seconds over windows extending to 20,000 hours. List mode programming supports complex test sequences.

Interface options include LAN (LXI Class C) and USB for seamless integration into automated test environments and networked laboratories.
