# Keysight E36311A 80W Triple-Output DC Power Supply, 6V/5A & ±25V/1A # Keysight E36311A 80W Triple-Output DC Power Supply, 6V/5A & ±25V/1A ## Key Features At A Glance - Triple-output design: a 6 V main rail plus two 25 V auxiliary rails in a single bench instrument - Output voltage ranges of 0–6 V and 0–25 V on the auxiliary channels across the series - Power output spans 80 W to 160 W across the three models - Low output ripple and noise with 0.01% line and load regulation - Over-voltage (OVP), over-current (OCP), and over-temperature (OTP) protection for the DUT - 4.3-inch LCD color display with color-coded channels and individual voltage/current knobs - E3631A code compatible; supports SCPI, IVI driver, web browser, and BenchVue control - USB standard on all models; LAN (LXI) standard and GPIB optional on the E36312A/E36313A - Low acoustic noise — typically under 26 dBA at no load via thermal fan-speed control The Keysight E36300 Series is a line of triple-output bench DC power supplies built for the test bench. Keysight positions the series to deliver the performance of system power supplies at an affordable bench price, combining low output ripple and noise with accurate voltage and current programming and readback so a design can be powered and measured with confidence. A bench DC power supply provides controlled, regulated voltage and current to a device under test. The E36300 Series is suited to powering precision circuitry, where its low normal-mode noise assures quality power, and to powering multiple analog or digital circuits or devices from a single instrument. Its built-in OVP, OCP, and OTP protection supports limit testing while helping prevent damage to the DUT. ValueTronics stocks and holds its own inventory in a 20,000 square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. ## Brand Heritage Keysight Technologies traces its measurement heritage through Hewlett-Packard, whose test and measurement business was spun off as Agilent Technologies in 1999. Agilent's electronic measurement group then became the independent Keysight Technologies in 2014, the brand under which this product line is sold today. ## Compare Other Models in This Series The E36300 Series comprises three triple-output bench power supplies that share a common architecture but scale in capability. Keysight describes the line as delivering the performance of system power supplies at an affordable bench price, packaging three outputs — a 6 V rail and two 25 V rails — into a single instrument across all three models. The series comparison distinguishes the E36311A as the 80 W economy model, the E36312A as the 80 W full-featured model, and the E36313A as the 160 W high-current model. The sections below summarize how the models differ; the comparison table that follows lists the per-model specifications in full. Each new model below is listed as its own dedicated product page with condition-matched pricing. Select the model that fits your output and feature requirements, then choose the available condition and configuration on that model's page. The E36311A is the 80 W economy model: its channels 2 and 3 operate in tracking mode only, it provides 2-wire sensing and a USB interface, and it does not offer data logging, output sequencing, LIST mode, or auto series/parallel voltage and current boost. The E36312A is the 80 W full-featured model, adding electrically isolated independent channels 2 and 3, 2- or 4-wire sensing, USB and LAN with optional GPIB, data logging, output sequencing, LIST mode, and auto series/parallel operation. The E36313A is the 160 W high-current model, offering twice the current of the other two — 10 A on the 6 V rail and 2 A on each 25 V rail — while carrying the same extended feature set as the E36312A. On the E36312A and E36313A, auto series/parallel lets channels 2 and 3 combine to reach up to 50 V or up to 4 A. The comparison table details each model's outputs, regulation, accuracy, and interface options.
