Be sure you have the latest FW installed for it to mean anything.

I've found out Tonghui has a Youtube channel with videos showcasing most of their instruments:

Including one that shows a bit about how their DC loads work:

Hello there,

I have a Tonghui DC load 8411. When I received it the firmware was very bugged, constant power mode was not working at all. The company answered in half a day and they sent me via email a new, working, firmware.
It still has some problems like the meter showing a DC offset also if it is disconnected (could be a problem of my unit).

About the rest it's a well built unit with some premium components inside (ST MOSFETs), I'd say it's a bargain for the price.

Hi Nico,


I, personally, will never buy anything from Tonghui again.

Sure, the HW may be just fine, but boy, if you ever need a bug fix, or any other type of support, FORGET IT !!!
(As you kow I have their LCR meter, and regret that purchase)


I own an iTech IT8513C+.   A bit more than what you are looking for, but I really like the unit:

Rating: 600W, 120V/120A
About $1200 USD  @AliExpress

iTech also makes smaller (<600W) variation if this is overkill for you ...

The UI takes a bit getting used to, but now I can set it up and am ready for work within seconds!


Cheers,
luudee
