Review: Very nice bench supply. - This is a very nice and not terribly expensive single output power supply. I have yet to use it extensively, but ran it through its paces the other night and found the features worked pretty much as expected. I especially like the programable memories, so I can set it up for different applications, and just tap the memory button and be ready to go. The over voltage and over current protections work well, as do the constant current and voltage functions. I do find the fine adjust a little odd, but that seems par for the course with these supplies. Finally, the ability to switch off the output and adjust the voltage and current with the output off is quite nice. FWIW, I've been doing electronics as a hobby and profession for pushing 50 years now.
Review: Excellent power supply - Very easy to use, accurate and reliable. If you look at forums this model comes highly recommended; such a high value product at this price point. Being a linear power supply it's a little wasteful, but I haven't noticed an excessive amount of heat, and while I haven't observed it myself, the waveform is said to have low ripple. If I needed another supply I would buy another without hesitation.

## Features

- ◆ HIGH PRECISION INSTRUMENT WITH MANY UNIQUE FEATURES - Very Easy setup with a rapid adjustment knob. There are buttons to switch to course or fine adjustment and a button to switch to voltage or current selection. The input voltage is switchable between 110/220 Volts for use in all countries.

- ◆ 4 DIGITS READINGS WITH BACK-LIT LED DISPLAY - With a 0.001V and 0.001A resolution, 4 digits provide more accurate and clearer visible readout for the voltage and current values with only 1 knob, extremely durable and easily visible even in low-light usage, meeting the needs of most people, ideal for business, small labs or the hobbyist at home.
- ◆ HIGH-QUALITY WITH ESSENTIAL SAFETY - Grounding wire, thermal protection, voltage and current overload and short-circuit protection ensure the safety.

There is also a lock button to prevent accidental changes.

### ⭐⭐⭐⭐⭐ Keeps providing constant power
*by J***M on November 20, 2025*

Great power supply. A little of the high size of pricing but unlike the less expensive models that will tap out of the correct voltage after 10 or minutes of run time, this just keeps on going.
