Tip from our expert:
This device is extremely intuitive to use. A simple power supply with the necessary extra functions such as memory slots and the option to program the power supply.

This popular programmable, linear power supply has an excellent price/quality ratio. With an adjustment precision of 10mV/1mA, the voltage and current can be regulated accurately. The power supply has a separate switch to turn the power supply on and off. The device has 5 memory slots for storage and recalling of output settings.

The Korad is programmable via the supplied software and via a USB or RS232 connection.


The difference between the two models we offer can be found in the connectors at the front. We offer a model with screw connectors and a model with safety connectors. The advantage of the model with screw connectors is that both banana plugs and separate wires can be inserted. Both models are identical in terms of functions and properties.

Good value for the money if one need a linear power supply. Not too heavy, moderate footprint.
Good quality materials.
It work as specified.
A plus is the PC connectivity. It can be programmed.
Lower than 1mV ripple.
Good voltage/current calibration (within 10mV/mA).
ON/OFF output does not has overshooting.

Highly recommended for moderate lab where 30V/5A is all you need,

A really good experience shopping for the first time from eleshop. The model of the power supply they sell here, seems to have solved issues present in earlier revisions of the product, that is, annoying fan and equally annoying beeper. This is the best linear power supply for the money!

The circuits are even newer than the revisioned ones I could find online before purchasing it.
No ripple,
No overshoot under load at 30V,
and only 90 euros before tax.

What else could I ask for?

PS. They even fixed the beeper. It has a clean pleasant sound now.
