IT6721 DC Power Supply

Very few reviews on this product so I was a bit hesitant to try it, but all the other power supplies in the $50 to $150 range with hundreds or even thousands of reviews had quite a high percentage (over 5%) of DOA and junk reports! With only 9 reviews for this supply that’s not enough to know if it is any better! I have only had it one day, but I put it through some tests and was very pleased. The manual must be downloaded and could stand for much improvement, but the unit performed very well and once I deciphered the manual, was very easy to operate and provided a wide range of coarse and fine control for setting values quickly. I thought my unit might have a bad fan, because it never came on during my 20 watt tests. But then I put an 80 watt load on it and after a few minutes the fan came on. It was still pretty quiet though and it went off seconds after removing the 80 watt load. One thing that you should be aware of is that you wont get 5amps out at 60VDC, it is a 100W power supply, so 20V x 5A = 100W. Anything above 20V , you do the math!

This seems like a high quality supply, with an accurate display. I've only used it a couple of times. However actually using it is a bit of a pain. It only has one control knob, and you have to use buttons to select what it does, for example, Voltage fine adjust, voltage course adjust, current fine adjust, etc. The display does not help at all.....it only tells you that you are in "Mode A", "Mode B", "Mode C" or "Mode D". You have to remember what each mode does. Each button has at least 2 functions and they are not clear. The manual very confusing and lists a bunch of additional modes but no explanation what they are, or how to use them. I probably should have bought a Uni-T, much easier to use but only 30V instead of 60V like this one.

Delivers full voltage and amperage as advertised. This is being used for DC heater testing which is not noise sensitive so i have not looked at the waveform on a scope, but a multimeter agrees.

So far this has been working great. From what I've read it seems this brand is owned by BK Precision but is the cheaper line. We have used BK precision power supplies for years, expect to get similar results from this for cheaper and better availability. Accuracy seems good, so far I have run it for over 24 hours over the course of a week.

Why not to send an spare fuse for the 220V option?… omg I can’t turn it on until I get one … so easy and cheap to have in consideration an 220V user

Hopefully it lasts. You can tell its cheap but the wide range of voltage is nice if it can maintain it.

Didn't come with plugs.
