Launched in 2020, the Kungber SPS series DC bench power supply has undergone a series of upgrades in detail. It has 2 colors plus 4 specifications, an all-metal body, and a 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 equipped with better materials and upgraded structure which makes it higher reliable and accurate, with lower ripple and noise. The new circuit design also makes it perform better on leakage protection, thermal protection, overload, and short-circuit protection. The SPS series will be a good helper in both laboratory and industrial use.


  • High Precision with 4-Digit and Power Display: Kungber 120V 3A DC benchtop power supply is a professional power supply regulation device that has a high resolution of 0.1V and 0.001A. You can easily tune it within 0-120V and 0-3A. The backlit 4-digit LED display provides a more accurate readout for the voltage and current value, visible easily even in low-light conditions.
  • Constant Voltage (C.V.) & Current (C.C.) Mode Automatic Conversion: Easy to dial in the desired voltage and current with the coarse and fine adjustment knob. The constant voltage/current mode can automatically switch with load changes. The conversion of constant voltage and constant current is indicated by the LED display on the front panel.
  • Compact and Various Application: This DC power supply is less than 3 lb and measures only 9.5 x 3.4 x 6.1 inches, applies for laboratory, school, repair, electrolyzation, electroplate, brush plating, lamp test, aging testing, battery charge, home DIY and other requirements. 5V/2A USB Interface could charge your cellphone and provide power for the device which you want to repair, no worry about running out of power.
  • Reliable and Safety: Many safety measures are adopted in Kungber DC bench power supply- Grounding wire, Leakage protection, Thermal protection, Voltage overload, Power overload, and Short-circuit protection. Kungber power supply uses premium electronic components to provide reliable working status and prolongs the life of the product effectively. When the working temperature is more than 122/50, intelligent thermal protection will active the cooling fan to lower the temperature according to the load.
