Electronic load, why only constants?
FriedMule:
Great replies, I do want a decent model and I do think maybe +25V at +3A would be nice, I'll look at all of your suggestions.
My knowledge about building electronic is to low for building my own reliable test gear.
unfortunately do I not have much money either.
Any more suggestions, also on what I shall look fore if I am using it for simulating DC loads below main voltage?

I recommend you check its specs and manual to see if that is what you need.
By the way, the term "constant" is a bit misleading. This doesn't mean that things cannot vary. It only means that this is the parameter that you're going to control, regardless of the others. So, in constant current (CC) mode, your dummy load will maintain the programmed current no matter how the other parameters (voltage, resistance) react. The same is true for CV or CR. Some models even offer CP (constant power).

Why would you ever buy BK precision when it's ITech (BK daughter company) sold at higher price? You could simply spend less or get higher end model at the same price. Also there is Maynuo.
FriedMule:
So ITech is the same as BK?
Yes there is Maynuo, Rigol and others but I do not know if they are okay or just "HangLow" models? :-)

Yes, I don't know if all models are exactly the same but most of them certainly is the same thing made at the same place. Maynuo is basically the same thing. It's not like there is a difference like between Rigol and Keysight. You'll hardly notice any difference, also there is only little price difference between Maynuo and ITech.
