## Description

From the manufacturer

Review: A good power supply - This is a decent bench power supply bought to replace an elderly linear supply that had failed. I haven't tested it to the limits of its stated spec but have now used it a fair bit at lower supply currents, and I am very happy with it. A push button selects output voltage or current limit with a single control to adjust the levels. That's my only quibble: if the control is inactive for a few seconds after adjustment the control is deselected - a little longer would have, for me, been better. On the whole though it is a good PSU.
Review: Easy to use and very safe power supply. - It was fast delivery and everything works as it should. Plugged into mains and straight away set up voltages and currents i need it for my work and stored them into memory and it performs really well and cooling is quiet as well, but that depends on a load of course.

## Features

### ⭐⭐⭐⭐⭐ Review
*by Z***S on 6 December 2023*

Can’t explain the reviews you’ll find for this brand. Let me say, this model is NOT loud at all, preforms to spec, has no odor, does not jump values quickly when setting the dial, and is dead simple to use. I wish I didn’t spend 2 weeks reading reviews and comparing models. This os a solid mid-level linear power supply in an Amazon selection of mostly switching power supplies. I use this on RF and microcontroller projects and I’m not seeing any major interference The only con is somebody mustve made a mistake on this power cord. As others have noticed, it’s not a good fit and falls out. I’ve had to tape it on and will be buying a different cord for it. Hopefully its just the cord and not the actual socket that has weird dimensions (depth seems too short) *UPDATE* bought the first power cord I could find, like the ones you use for a PSU, fit perfectly. Something very off about the one that comes with this unit, it’s about 1/4 inch too long, non-standard
