Description
Sensor modules, small fans and relay boards often run on 12 V. The Keysight E36103B power supply is a single-output benchtop source rated 20 V, 2 A and 40 W, so a 12 V load fits with room to spare. Lost in HCM quotes it for rental and sale in Vietnam.
Twelve-volt work with headroom
The E36103B belongs to the E36100B Series of benchtop DC supplies. Its 20 V ceiling leaves space above a 12 V rail, so you can test a board slightly above and below its nominal supply. Because 20 V times 2 A equals 40 W, the two limits describe one corner of the envelope. At 12 V, then, the 2 A ceiling still applies.
Check the load before you connect
Two amps sounds modest, yet motors and relay coils can pull more at start-up. So check the peak current of your load, not only the average. Set the current limit first, then raise the voltage in steps. In addition, watch the status flags on the display, because they report over-current and over-voltage events.

E36103B questions
Why does the rating list 40 W when I only see 20 V and 2 A?
Because 20 V times 2 A gives 40 W. The three numbers describe the same corner of the output range.
Is rental better than buying a Keysight E36103B power supply for a 12 V bench?
Rent for a project with a fixed end date. Buy when the same bench needs the supply every working day.
Can I run it from standard bench mains?
The listing describes universal benchtop AC input. Even so, confirm your site voltage and the supplied power cord with Lost in HCM before delivery.
