Adjustable DC power supply 30V 60V 120V Digital Lab Bench Voltage Regulator

About this deal

This is an adjustable DC bench power supply available in several variants, covering output voltage ranges of 0-30V, 0-60V, or 0-120V, with current options depending on the chosen model. Variants include models such as 0-30V/5A (150W), 0-60V/5A (300W), 0-30V/10A (300W), and 0-120V/3A (360W), available in white or black. Output voltage and current are each controlled by two variable resistors offering coarse and fine regulation for precise adjustment. The unit features a multi-digit LED display showing output voltage, current, and power, and typically includes a 5V/2A USB port. This type of supply suits phone repair, lab use, battery charging, and plating applications. It is also widely used in industrial production, repair and maintenance, and education and research. Comprehensive operating protection functions are included, alongside the dual-potentiometer design for more precise adjustment. The switching design keeps the unit compact and lightweight compared to traditional linear bench supplies, making it a practical choice for both professional and hobbyist workbenches.
