Uses for DC programmable load in home lab

ledtester:
You can get it from Banggood - I've had a good experience with them when items arrived damaged or incomplete:

https://usa.banggood.com/Original-ZHIYU-60W-110W-9_99A-30V-Constant-Current-Electronic-Load-Aging-Battery-Capacity-Tester-p-1146280.html

Also - that page has operating instructions in the description of the item.

This page also has operating instructions and includes how to access the serial port to get a constant readout of the load's voltage:

Many thanks ledtester, i'll get one.

I thought I was the only one who wondered why electronic loads were such a popular project!  ???

I tend use old high power rheostats and resistors for PSU testing. Obviously they are passive rather than active so not capable of constant current load (easy battery life calculations etc.) but they provide a benign bulletproof load for testing thermals and voltage sag.

I suppose active loads are useful for testing transient performance... assuming that it's not the load that is unstable!

swgertsch:
Purchased a ZHIYU 110W, 30V, 9.99A Constant Current Electronic Load-Battery Tester from BangGood a couple of years ago.
Documentation available left a lot to be desired so I cobbled together a English language User Manual.
