Wanptek introduces its new series of miniature switching DC power supplies, designed for compactness and precision. These power supplies offer adjustable output voltage and current through variable resistors, ensuring accuracy and convenience. The panel features high-precision two or three-window digital displays for voltage, current, and power, allowing users to monitor operating conditions and parameters intuitively. With its compact design, automatic switching between constant voltage and constant current modes, and advanced protection features, it is ideal for various applications.
