Hello everyone
I'm new to the forum so i'll like to contribute a little something.
I purchased myself an electronic DC load for my testing purposes at work, I looked everywhere and looked at the Maynuo and BK units plus some others.
After some extensive self research and including reading on these forums I decided to venture a little into the unknown with the Applent AT8612.
I've noticed that their LCR meters are popular so i wanted to see how their DC load measured up.
My initial criteria was a 300W load, the Maynuo 300W units were a bit pricey so the AT8612 became even more tempting at US$360+shipping.
After a few months using it pretty much everyday I can say I am very happy with it.
Some thoughts:
I'm a sucker for LCD screens, you could sell me a poo if it had an LCD on it. The menu and screen is truly wonderful to use and looks even better than the photos portray.
Binding posts that I can use my standard (non shielded) 4mm banana plugs - a massive win! It still has binding posts too. This is a HUGE plus!
There was a UI bug where under certain conditions it wouldn't read the voltage correctly, but after contacting Applent directly the next day they emailed me a firmware update that fixed the problem.
4 wire sense is very useful and accurate.
Battery capacity test is quite useful.
Extremely quiet, even under full load the fans are very quiet but still move sufficient amounts of air.
It can test much of your standard tests like:
CC, CV, Constant Power, Constant Resistance, Transient CC CV CP CR, Battery testing, Sequence testing, Automatic testing.
150V, 30A, 300W.
As I said, it's only a quick tear down and brief review. I am more than happy to do a more extensive tear down and answer more detailed questions from my first hand experience.
The micro-controller is behind the transformer and I couldn't read it properly so in my more detailed tear down i'll take a closer look.
