Good build quality
Don’t expect the probes, also the ammeter only works when there is load don’t get confused

Good quality product, but no cables included
Transformer based power supply. Goes up to 32v 5Amps. The fine tuning knob is a little finicky, but I have a tough time precisely setting the values. It is a minor inconvenience. It did not come with leads and I had to scramble to find something that fits (it uses banana plugs for anyone wondering). I found a old set of multimeter probes which fit. I have used it few times so far and it works fine. Quality of switches and plastic is good. The display is also quite nice. I feel it is about 1k more than other competing products.

Very good quality power supply. Stable output
This is our third vartech power supply. Build quality is very good. Heavy transformer is used and the output pausing is helpful. No issues till date. Tech support is also very good as usual from VAR TECH.

Excellent
Measured the output current and voltage with standard multimeter and found the supply good enough. Worth to have it in lab at home or even at professional laboratory.

current fluctuation is very high that it can not be used
The current is unstable the fluctuation is very high , we understand slight change do happen as development boards are connected and functional. But we noticed that this device does not stop for event 1 , 2 seconds also , the variation of fluctuation is very high. Please advise me if there is a way we can get this fixed. unfortunately we could not return with in the given time frame.
