KEYSIGHT E36441A, 4-Channel Autoranging Bench Power Supply Introduction
KEYSIGHT E36441A is a 400 W programmable power supply with four fully independent and isolated outputs, each delivering up to 32 V and 10 A (160 W/channel). Thanks to autoranging, you get maximum flexibility for high current or high voltage loads, and with the optional E364SNP kit, you can easily connect channels in series (up to 128 V) or parallel (up to 40 A) – all with one touch, no manual cabling.
- 4 outputs: 160 W / 32 V / 10 A each, for a total of 400 W
- Autoranging design: full power at a wide range of voltage/current combinations
- Extremely low ripple & noise (<1 mVrms), fast transient response (recovery <55 μs)
- Color-coded 7-inch LCD display, separate knobs for each channel, numeric keypad, status LEDs
- Comprehensive device protection: overvoltage, overcurrent, overtemperature, three current limit modes
- 2-wire and 4-wire remote sense on all outputs for precise voltage at the load
- Data logger, output sequencing, LIST mode, tracking, adjustable slew rate, and more
- Front/rear terminals, USB/LAN connectivity, SCPI programming, and emulator mode for easy instrument replacement
Target Applications
- Powering and testing analog & digital circuits, devices, and modules
- Parallel/series high power applications up to 128 V or 40 A
- Automated test systems (SCPI, LAN, USB)
- R&D, production test, education and lab benches
- Power supply design, embedded systems, burn-in tests
Competitive Advantages
- True autoranging: Full 160 W per channel, available from low voltage/high current to max voltage (32 V/10 A, 160 W per output)
- Fast, accurate, and quiet: <1 mVrms ripple/noise, fast load recovery (<55 μs), quiet operation, <0.01% line/load regulation
- Advanced protection: OVP, OCP, OTP, 3 current limit modes, full isolation between outputs
- Productivity & test control: Data logger, LIST & sequence mode, output tracking, adjustable slew rate, tracking mode, front & rear terminals
- Modern connectivity and software: USB, LAN/LXI, BenchVue software, emulator mode for Rohde & Schwarz HMP4040
