Regulated Bench Supply 30V 10A

This adjustable DC bench power supply delivers 0-30 volts and 0-10 amps from a single channel. A backlit 3-digit LED display shows readings with 0.1 V and 0.01 A resolution. It includes coarse and fine adjustment knobs for precise voltage and current setting.

Hobbyists and Repair Technicians

The unit suits hobbyists, students, and repair workshops needing a compact variable source for circuit testing or battery work. Builders requiring multiple independent channels or higher power density for rack integration should look at other equipment.

Desktop Setup with Included Accessories

The supply ships with a US power cord and 4 mm alligator clip leads with banana plugs for immediate bench use. A built-in thermo-sensor fan and dual heat sinks manage heat automatically. Protections cover current limit, thermal events, voltage overload, and short circuits.

Questions about this item

What mains lead do I need to plug the 30V 10A bench supply into a UK socket?

The box includes a US power cord, so you will need a UK IEC C13 mains cable or a travel adaptor to connect it to a British wall outlet.

Can I run the 30V 10A unit from the same bench as a vintage linear supply without fan noise interfering?

Its thermo-sensor fan and twin heat sinks only spin up when internal temperature rises, keeping acoustic output low enough to share a workspace with quieter legacy gear.

How do I verify the 0.1 V and 0.01 A display resolution is accurate after first power-up?

Set a known reference such as a 5 V USB rail or a precision 10 V source, compare the three-digit LED readout, and confirm the coarse and fine knobs track each step without drift.
