Review of the Korad KEL103 programmable load.
<< < (9/11) > >>

@HKJ Thanks, I will try it  :-+
Grandchuck:
I have a Multicomp MP710259 (which I assume is equivalent to the KEL103 and the Tenma 72-13210).  The software supplied on CD ROM was version 4.1 and is useable now, but it took some experimenting.  I am using the supplied USB cable.  One help is to open the folder found in Program Files (x86) and change the permissions by right clicking the Configuration settings files, select Properties, then Security, then Users, then Edit, then Users and finally Allow so those files can be written to by the program.

When using the graphs, you can click on the min and max values and change the scales.  Also, you can right-click a chart and then clear it.

I hope some others discover more about this software as it seems at least somewhat useful.  Thus far, I am liking this electronic load a lot!

For another software check https://www.eevblog.com/forum/testgear/program-that-can-log-from-many-multimeters/
The current version do not support the load, but next version will (It only requires a small change in a definition file and information about it is posted in reply #1526).

The manual is garbage. For example...in battery test mode you have to specify (even if you dont need it) a max discharge time limit and consumed AH limit. The manual states that this is in seconds (discharge time) but this is wrong. You can set the max time to 9999, but this is minutes and not seconds.  The same with AH, its 9999 AH.
The manual is also wrong/confusing with different other things.

Yep, it quite confused me cause it counts somewhat like seconds right to the dot but these are actual hundredth of a minute.


I like the unit with the simple and very clear segment display.
A bit annoying is the fan on the heatsink at the front area that turns on 100% when going above 2 A load. Is that some kind of shunt / measuring construction?
Also sometimes the main fan is not switched off although load is turned off and the heatsink is cooled down. Don't understand the magic behind this yet. ^^
Bravo:
Yes it is possible to buy from the factory for US$309 excluding shipping. I think it will be cheaper from Ali or Bangood.
If you going to buy from Ali, ask the store if they have stock for immediate dispatch, otherwise you will end up like me, & have to cancel the order & wait for a refund because they can't get stock in time.
