Clearance - 30v 3A TENMA PSU

14rhb

I regularly look through the clearance lines on CPC Farnell (a UK subsidiary of Farnell/Avnet) and currently they have a Tenma 30v/3A PSU for £51.84 (incl. tax and shipping)....not bad if someone is looking for a reasonable entry level PSU.

 

See https://cpc.farnell.com/tenma/72-2705/power-supply-0-30v-programmable/dp/IN0763769

    Hi Shabaz, that’s a nice set of measurements! I was wondering what you’re using for the 3A load? I’ve got a project driving a very inductive load at a constant current of around 2A using PWM at around 500Hz, and want an electronic load for testing with, so any recommendations would be much appreciated!

    Hi!

    The constant current was using a BK8600 load (review here), it's got an easy-to-use front-panel interface, and simple to automate if desired too. If it's for personal use, there's a lower-cost Tenma load, but I've not tried it.

    It's my third BK Precision piece of equipment, it seems very usable to me. Most of the electronic loads (including the Tenma one it seems) use large binding posts, so normal 4mm banana test leads may not fit, but the end of the test lead could be cut off and a M6 lug crimped on.

    Thanks Shabaz, I’ll take a look! I’ve got a BK Precision signal generator and am very pleased with that, so am likely to stick with the brand too.
