# Keysight E36103B 20 V, 2 A, 40 W Single-Output DC Power Supply (Pre-Owned) # Keysight E36103B 20 V, 2 A, 40 W Single-Output DC Power Supply (Pre-Owned) ## Key Features At A Glance - Five models spanning up to 100 V or up to 5 A — pick the model that matches your DUT's voltage and current needs - Standard LAN (LXI Core) and USB 2.0 (TMC488) on every model for SCPI and IVI automated test systems - Compact 2U quarter-rack form factor saves bench space - High-contrast OLED display readable from across the bench, even at a sharp viewing angle - Overvoltage, overcurrent, and overtemperature protection safeguard the DUT and the supply - Store and recall up to 10 complete instrument setups from non-volatile memory - Built-in Web interface plus BenchVue software support for remote control, logging, and visualization - Highly accurate low-current measurement for demanding low-current readings The Keysight E36100B Series is a family of programmable single-output DC bench power supplies, the latest addition to Keysight's family of bench power supplies. It is engineered to power designs safely and quietly during manual tests or automated sequences, with five models offering up to 5 A or up to 100 V so a user can choose the model best suited to the application. Compact size, an OLED display, and standard remote I/O are emphasized across the line. A DC power supply delivers controlled, regulated DC power to a device under test, providing the known voltage and current a circuit needs to operate while it is being characterized or debugged. The E36100B Series is intended for both bench-side manual work and computer-controlled automated test sequences, and includes a highly accurate low-current measurement feature for demanding low-current measurements on a connected DUT. ValueTronics stocks and holds its own inventory in a 20,000 square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit is inspected and functionally verified in-house by our technicians before it ships, while new units ship factory-sealed exactly as received from the manufacturer. Keeping equipment on hand lets us match the right instrument and condition to a specific application and get it out the door quickly. ## Brand Heritage Keysight Technologies traces its roots to Hewlett-Packard, whose test and measurement business was spun off as Agilent Technologies in 1999. In 2014, Agilent's electronic measurement division was established as Keysight Technologies, the company that produces this instrument today. ## Compare Other Models in This Series The E36100B Series comprises five single-output programmable DC bench power supplies that share a common 2U quarter-rack platform, OLED display, front-panel knob-and-keypad interface, and standard LAN (LXI Core) and USB connectivity. The models differ primarily in their maximum voltage and current ratings, letting a user select the output envelope that fits the device under test rather than over-buying capability. Every model in the series carries the same programming and readback accuracy class and the same protection set — overvoltage, overcurrent, and overtemperature — so the choice between models comes down to the voltage and current required at the output, not to feature tiers. Each model below links to its own dedicated product page with condition-matched pricing. Select the specific model your application requires, then choose the pre-owned listing that fits your budget and lead-time needs. The five models span a range of output envelopes: the E36102B is rated 6 V / 5 A (30 W), the E36103B 20 V / 2 A (40 W), the E36104B 35 V / 1 A (35 W), the E36105B 60 V / 0.6 A (36 W), and the E36106B 100 V / 0.4 A (40 W). As maximum voltage increases across the line, maximum current decreases, so higher-voltage models trade current capacity for voltage reach. Because the models differ in output rating, their per-model regulation, ripple, accuracy offset, and resolution figures also scale with the rating. Refer to the comparison table that follows for the exact voltage, current, and power values of each model so you can match the supply to your DUT's requirements.
