Adjustable Lab Power Supplies

Adjustable lab power supplies give engineers, technicians, and electronics hobbyists precise, repeatable control over voltage and current for bench testing, prototyping, circuit design, and equipment repair. Each unit features a digital display for real-time voltage and current readout, fine and coarse adjustment dials, and constant voltage / constant current (CV/CC) modes for safe, accurate operation across a wide range of applications.

Built for the workbench rather than the panel, these adjustable DC power supplies are compact, stable, and easy to dial in — making them a reliable choice for R&D labs, repair workshops, electronics education, and hobbyist projects where precise, variable output is essential. Low ripple and noise, fast transient response, and short-circuit/overload protection help protect sensitive components during testing.

Whether you're calibrating a circuit, powering a prototype, testing components under load, or diagnosing a fault, a Wanptek adjustable lab power supply gives you the fine control a fixed-output supply can't. Browse the range below by voltage and current rating to find the right bench power supply for your setup.
