DC Power Supply Variable with Memory 30V 5A Bench Power Supply with 4-Digits LED Display Adjustable Regulated Switching Power Supply with Memory Recall，Output Disable Button

My first PSU arrived not working properly (JESVERTY branded). This NANKADF 5A PSU was it's replacement. I'm new to these bench PSUs, and already appreciate the awesomeness of this unit! The front facing power switch, as well as output button is a MUST. I avoided this push button style for the first PSU, and HATED the course and fine 2 knob system for voltage as well as current. This single button design for each is very simple, responsive, and the next higher value digit rolls over when rolling up past 9 or down past 0, making it VERY intuitive. The 3 memory settings are another MUST have if ever working with more than 1 standard voltage. Mine are set for 3.3, 4,2 and 5.1v. Awesome that the current limit gets stored with the voltage. No idea about fan noise because it hasn't come on yet after hours of use. The manual states it only comes on when needed, so I'm grateful I didn't choose a unit that the fan is on full time (from reviews of other units, it sounds annoying). The manual is worth reading, and describes the functions and use much better than the one I returned. The only tick against this unit is it came with the AC switch on the back set for 230V, rather than 115V for the country of purchase. Reading the manual first, it emphasized checking this before first use to prevent PSU damage. So another thumbs up for well written manual. I strongly recommend this PSU to others starting out as I am. But boost the bucks for the 10A version, because this is such a good (and pleasure to use) unit, it would be a shame to outgrow it's current limit without needing additional functions.

Very nice power supply. I bought 2 of them over 2 years ago for my home lab. Still working well. I don't use the USB charger or programmable features. I do use the 3 memory buttons on the front panel. Very convenient setting my frequently used voltages. The metal casing is like added bonus. The voltage reading seems accurate. The current is not accurate when at low values which is why I didn't give it 5 stars. I had an ammeter set-up and measuring 9.3mA but the power supply display shows 4mA. Would be nice if it was more accurate. Overall, happy with the product. Didn't see any electrical noise issues and very reliable. Using for over 2 years and still working well.

I bought this specifically for my electronics repair bench, and love the presets, allowing for voltage as well as current presets. Also love the output enable switch. Super handy! A solid performer.

Used this for about 10 minutes and the screen went blank, never came back on. Detective unit. Unit was replaced, second one seems to be working fine. 16 hours and been on the entire time without issue.

I’ve used this for several applications.
