DC Laboratory Power Supply 30V 60V 120V Adjustable Bench Switching PSU UK

About this deal

A DC laboratory bench power supply with selectable output voltage of 30V, 60V or 120V is a versatile switching-mode PSU well suited to electronics engineers, hobbyists, students, and repair technicians who need a reliable, regulated DC source across a wide voltage range. Units of this type typically offer high-precision voltage and current control, automatic constant-voltage/constant-current (CV/CC) mode switching, low-ripple output, and a clear 4-digit LED display. The 30V, 60V and 120V variants commonly cover power ratings of around 150W, 300W and 360W respectively, with current options of 3A, 5A or 10A depending on the chosen voltage range. Bench PSUs of this kind are designed for use in laboratories, education, electronics repair, battery testing, and DIY projects. The switching topology keeps the unit lighter and more efficient than a traditional linear design, making it practical for everyday workbench use. Common features on comparable models include fine and coarse adjustment knobs for achieving an exact desired output and an internal cooling fan to keep temperatures low and prolong the life of the unit. The UK-rated mains input means it is ready to use straight away with a standard British plug.
