Keysight E36231A Autoranging DC Bench Power Supply
The Keysight E36231A, part of the E36000 series, is a 200 W autoranging DC bench power supply designed for engineers who need clean, reliable power for demanding benchtop test applications. As part of the Keysight E36200 Series, the E36231A delivers a 0 to 30 V, 0 to 20 A single-output range with autoranging technology, allowing higher current availability across output voltages for flexible device testing. Low output ripple and noise, precise programming and readback accuracy, 2-wire or 4-wire remote sensing, and layered protection features help users power a device under test with confidence while improving measurement accuracy and protecting valuable prototypes.
E36231A Specifications and Key Benefits
Power output: 200 W autoranging DC power supply for benchtop applications that require up to 200 W of clean, controlled power (V x A cannot exceed 200W).
Output rating: 0 to 30 V and 0 to 20 A, giving engineers flexible voltage and current coverage from a single-output supply.
Clean output power: Less than 350 µVrms ripple and noise helps support accurate testing and stable device characterization.
Programming accuracy: Voltage accuracy of 0.03% + 4 mV and current accuracy of 0.1% + 6 mA support precise output control.
Readback accuracy: Voltage readback accuracy of 0.03% + 4 mV and current readback accuracy of 0.1% + 6 mA allow front-panel measurements without relying on an external multimeter for many bench tasks.
Low-range current measurement: Low-range current accuracy of 0.25% + 160 µA and 20 µA remote readback resolution help characterize low-current behavior.
Load and line regulation: Better than 0.01% + 2 mV voltage regulation and better than 0.01% + 250 µA current regulation help maintain steady output as load or power-line conditions change.
Remote sensing: 2-wire local sensing and 4-wire remote sensing compensate for voltage drops in test leads, improving voltage accuracy at the device under test.
Protection features: Over-voltage protection, over-current protection, delayed over-current protection, constant-current limiting, and over-temperature protection help safeguard connected devices.
Connectivity and automation: Standard USB and LAN, optional GPIB (order E363GPBU), SCPI programmability, IVI driver support, web browser control, and BenchVue compatibility simplify automated test setup.
Productivity tools: Data logging (up to 21,845 hours and up to 5MB of data), output sequencing, LIST mode, adjustable voltage slew rate, and internal memory help engineers capture test results and simulate power conditions.
Bench-friendly design: 4.3-inch color LCD, individual voltage and current knobs, front and rear output terminals, thermal-control fan speed, and compact 5.8 kg form factor support everyday lab use.
E36200 Series DC Power Supplies
The E36200 Series includes both single-output and dual-output power supplies designed for bench applications requiring up to 400 W of power. Its autoranging capability provides maximum available current across the entire output voltage range. For applications that require up to 40 A (E36233A) or up to 120 V (E36234A), the dual outputs can be automatically combined in parallel or series mode to create a single output with twice the available power. A single-output model is suitable for devices with power requirements below 200 W, while a dual-output model can power two devices simultaneously.

Keysight E36231A FAQ
What is the Keysight E36231A used for?
The Keysight E36231A is used to power and characterize electronic devices on the bench when engineers need a single-output autoranging DC supply with up to 30 V, 20 A, and 200 W. It is well suited for powering a device under test during design validation, troubleshooting, production support, and general lab testing.
How does the autoranging feature work on the E36231A power supply?
Standard power supplies use a rectangular operating curve that limits current at lower voltages. Autoranging automatically adjusts the voltage and current limits dynamically. This allows the E36231A to deliver any combination up to 30 V and 20 A, provided the total output does not exceed its 200 W power envelope.
Does the E36231A support remote control and automated testing?
Yes. The E36231A supports SCPI programming and can be operated through USB, LAN, optional GPIB, IVI drivers, a web browser, or BenchVue software. These interfaces make it easier to integrate the supply into automated test systems and capture power-supply data for reports and documentation.
How does the E36231A help protect the device under test?
The E36231A includes layered protection features such as current limiting, delayed over-current protection, over-current protection, over-voltage protection, and over-temperature protection. It also supports 4-wire remote sensing to improve voltage accuracy at the device under test, helping reduce the risk of inaccurate power delivery caused by lead voltage drops.
E36200 Series DC Supplies are NB2-class performance grade, what does that mean?
NB2-class is a advanced benchtop DC supply. For labs requiring more power and precision, Advanced power supplies deliver up to 400 W of power, with low-noise, autoranging features, flexible output combinations, built-in protection, and full automation capabilities for daily testing and validation.
