Keysight E3631xA series PSU are entry level triple-channel linear 2-quadrant DC sources. Today in this review E36312A model will be reviewed and tested. This benchtop power supply was introduced to market in 2017, at MSRP $1400 USD for base E36312A (w/o GPIB option) model.
Key features of this model are as below:
- Output rating is 80 W, with 1 output rated for 6 V 5 A, and output 2 and 3 rated for 25 V 1 A.
- Three independent isolated outputs, with integrated ability to series or parallel outputs 2 and 3 together.
- Programming accuracy: 0.03% + 2 mV / 0.04% + 3 mA on CH1, 0.03% + 5 mV / 0.04% + 2 mA on CH2 and CH3.
- Noise/Ripple (20 Hz – 20 MHz) : <350 µV rms/2 mVpk-pk
- Low noise help to provide quality power for precision circuitry applications.
- Accurate voltage/current programming and read back capability.
- Low current range to 1µA resolution when load current is < 20 mA.
- Protection includes OVP, OCP, OTP
- 4.3” color LCD to show the voltage and current of all three channels at the same time.
- Color-coded channels to simplify manual set-up.
- Datalog for time-stamped data to external USB thumb drive for data analysis.
- USB/LAN interface as standard with Option GPIB.
- Complex sequences of output changes with rapid, precise timing and synchronized with internal or external signals to simulate on/off modes.
- Full 4-wire remote sensing on each output at rear screw terminal blocks.

I’d like to express credits and appreciation to Keysight team for making this review possible. It was received as a prize for my submission to Power Up Your Bench Contest held by Keysight from August 28, 2017 till January 26, 2018. Thank you, Keysight!
Decent triple channel linear power supply is a very welcome addition to my lab gear to enable more experiments with various analog and digital designs, related to measurements, prototyping and electronics tinkering.
