DC Power Supply Variable with Memory, 30V 5A Adjustable Switching Regulated DC Bench Linear Power Supply with Memory Recall and Output Disable Button 4 Digits Display and Alligator Leads

Easier to Set Values - Encoder switch is used on Kungber dc power supply 2021 version to replace the potentiometer switch which is widely used but not easy to adjust. On this version you can just set Voltage and Current instead of adjust. Make works accuracy, easy and fast.
4 Groups of Internal Memories - You can set 4 groups of commonly used Voltage and Current combination and easily recall them by press M1-M4. Use the ADJUST knob to set new combinations.
Output Switch Control - Sometimes we need to switch between different voltage or current outputs, but we often forget to unplug the previous instrument and cause to burn out, which often occurs in the maintenance. Output switch is designed to solve this problem. By pressing the On/Off key, the required voltage and current can be adjusted without the actual output power, which makes this benchtop DC power supply more secure and more energy efficient.
Reliable and Safety - Kungber variable power supply use premium electronic components, provide reliable working status and prolong the product life effectively. Many safety measures are adopt in Kungber power supply- Grounding wire, Leakage protection, Thermal protection, Voltage overload, Power overload and Short-circuit protection. When the working temperature is more than 122/50, the intelligent thermal protection will activate the cooling fan to lower the temperature according to the load.
Compact and Various Application - This DC power supply is less than 3 lb and measures only 9.9 x 3.3 x 6.7 inches, with a high resolution of 00.01V and 0.001A, led 4 digits display. You can easily tune it within 0-30V and 0-5A, applies for laboratory, school, repair, electrolyzation, electroplate, brush plating, lamp test, aging testing, battery charge, home DIY and other requirements.

Kungber SPPS-S Series DC Bench Power Supply
Launched on 2021, Kungber SPPS-S series DC bench power supply goes further than the SPS series. On the basis of previous version, the SPPS-S series adds some very practical functions: memory recall, output switch, and panel lock are all very commonly used functions. In addition, current and voltage adjustments have also become easier and more precise. Same as the SPS version, the SPPS-S series also has 2 colors plus 4 specifications, all-metal body and more compact size. And at the same time, we still see quality reliability as the top priority for DC regulated power supply. The series is equiped with a better materials and upgraded structure which makes it higher reliable and accurate, lower ripple and noise. New circuit design also make it perform better on leakage protection, thermal protection, overload and short-circuit protection. The SPPS-S series will be your good helper in both laboratory and industrial use.

High Quality Circuit Board
High quality circuit board makes the DC power supply stable and high reliably.

High Resolution
4-Digits LED display with power display

Memory Storage and Recall
You can set 4 groups of commonly used Voltage and Current combination and easily recall them.

Let's take M1 for example

How to Save: press M1, then set values, then press M1 again to save.

How to Recall: press M1, then press On/Off.

Output Switch
The On/Off button allows you to adjust Voltage and Current without having to disconnect load.

What's more important, on SPPS-S series you can adjust the current without having to short the wires
