Variable bench supply for lab and repair

This single-channel DC power supply delivers 0-30 V and 0-5 A with a four-digit LED readout showing 0.01 V and 0.001 A resolution. It suits electronic maintenance, scientific research, teaching and DIY projects where precise, stable output is required.

Check mains voltage and bench space

The unit ships with a US power cord and measures 226 x 82 x 138 mm, weighing 2.95 lb. Verify that your bench can accommodate the footprint and that the mains supply matches the cord provided before ordering.

Replaces fixed-voltage adapters and basic units

Unlike fixed-output wall warts or supplies without metering, this model adds coarse and fine adjustment knobs, automatic CV/CC crossover and full protection against over-current, over-voltage, over-temperature and short circuits. The jump is worth it when you need repeatable voltage and current limits for component testing or circuit development.

Questions about this item

Does the unit ship with leads and a mains cable, or must I buy them separately?

The package includes a 20-inch 4 mm alligator-clip lead set with banana plugs and a US power cord, so nothing extra is required for basic operation.

Which voltage and current range does this model cover?

It provides a single-channel output adjustable from 0 to 30 volts and 0 to 5 amps with 0.01 V and 0.001 A display resolution.

How accurate is the 4-digit LED readout when the supply is under load?

The display shows values to 10 mV and 10 mA precision, and the unit automatically switches between constant-voltage and constant-current modes as the load changes.
