Adjustable 120V 3A DC Power Supply with Memory Recall and Output Disable Button

The Kungber SPPS-S Series DC Bench Power Supply was launched in 2021 as an upgrade from the SPS series. It adds practical features like memory recall, output switch, and panel lock while making current and voltage adjustments more precise. With 2 color options and 4 specifications, the all-metal and compact body model continues the tradition of prioritizing quality reliability. The series uses better materials and an upgraded structure, resulting in higher reliability, accuracy, and lower ripple and noise.

The introduction of a new circuit design further enhances the power supply's performance in terms of leakage protection, thermal protection, overload, and short-circuit protection. The SPPS-S series is suitable for use in laboratories and industrial settings.
