0-100/150/200/300V 0-3A 5A 10A Lab Adjustable DC Bench Power Supply Variable；

About this deal

A lab adjustable DC bench power supply with variable voltage output of 0-100V, 0-150V, 0-200V or 0-300V and variable current output of 0-3A, 0-5A or 0-10A. This type of unit converts AC mains into a steady DC output, with the ability to regulate both voltage and current independently, making it highly adaptable for a wide range of applications. It is well suited to electronics engineers, hobbyists, students, and technicians who need a reliable, controllable power source on the bench. A key feature of this class of supply is its two modes of operation: constant voltage (CV), where the set voltage is maintained regardless of load resistance, and constant current (CC), where the set current is maintained regardless of load resistance. Typical uses include circuit testing, factory production line testing, and repair work on mobile phones, computers, electrical appliances, and car electronics. Many models in this category include built-in safety systems such as voltage limiting, overcurrent protection, and automated temperature regulation, helping to protect both the user and the unit itself.
