The Keysight E36441A is a four-output autoranging bench DC power supply that delivers 400 W of total power, with each of its four outputs rated at 160 W, 32 V, and 10 A. It pairs accurate voltage and current programming and readback with layered device protection, so an engineer can power a device under test with confidence.
The instrument is designed to address applications that test multiple devices or test points simultaneously. A single E36441A can power several analog or digital circuits at once, saving bench space compared with operating multiple single-output supplies. Its tracking mode varies four symmetrical voltages together, a convenience when supplying the balanced positive and negative rails required by operational amplifiers and similar circuits.
ValueTronics stocks and holds its own inventory in a 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, and has specialized in new and used test and measurement equipment since 1992.
Keysight Technologies traces its test and measurement heritage to Hewlett-Packard, whose instrument business was spun off as Agilent Technologies in 1999. Agilent's electronic measurement business then became the independent Keysight Technologies in 2014.

Important: The optional E364SNP Series and Parallel Kit does not include four-wire remote sense.
Important: Accuracy specifications are after 1 hour warm-up with no load and calibrated at 23 ºC ± 5 ºC.
Important: Specification may degrade when the unit is subjected to an RF field ≥ 3 V/meter.
Recommended pairing: add the E364SNP Series and Parallel Kit to combine all four channels into a single output of up to 128 V or 40 A for higher-voltage or higher-current needs.
