Product description: Laboratory power supply Korad KKG305P 0-30V 0-5A

The laboratory power supply is an absolute must-have when running and repairing electronics. The Korad power supply is characterized by programmable memory and smooth voltage regulation in the range from 0 V to 30 V and current in the range from 0 A to 5 A. It has an RS232 / RS485 and USB interface. It is cooled by a fan that runs continuously, and its speed depends on the load. The product is also equipped with clear displays allowing for comfortable observation of parameters.

The main functions of the power supply:

  • The device can operate in the following modes:
    • C. V. - DC voltage of output 
    • C. C. - DC load
  • The system is equipped with protection from surges and overloadsHas two kinds of protection:
    • OVP (overvoltage protection)
    • OCP (overcurrent protection)
  • The PSU has a 5 storages to save current, voltage and operation modes
  • Has the accuracy of indications of the current up to 3 decimal places
  • Equipped with a digital screen display showing all functions used
  • Cooled by a built-in fan
  • For communication, it uses the RS232/RS485 and USB interface

Can't go wrong for the price. Very well done. Thank you
Miroslav 10.01.2023 Confirmed purchase Translated review
It does what I want it to do.

Looks pretty solid, not blowing total chinosis. It makes a much better impression than the mass of cheap power supplies where the voltage / current is regulated with analog potentiometers. And on the other hand, not as expensive as the more professional Rigols or Siglents (but also not as advanced). Home just in time. It's good that the seller did not seal because you can look inside and check how it is made and whether the power supply will not try to kill us. In a few places I decided to give additional insulation with webbing tape, but other than that it's OK. Power supply on several printed circuit boards, connected by bundles with connectors. Unfortunately, the manufacturer glued them with white silicone for fun, as if the equipment was to be used in a tank. A large transformer, the main winding has some taps but I haven't figured out how it is controlled, anyway there are no relays there. The voltage on the filtering capacitor (6800uF) varies stepwise depending on the output voltage, probably to limit the power losses on the final transistors. Final transistors and rectifier bridge on a large heatsink cooled by a variable speed fan (the fan stops when no load is applied). The set voltage/current is regulated precisely - it corresponds well to the indications of a 5-digit multimeter (22000) with an accuracy of 0.5%. On the other hand, the meter/display built into the power supply has quite poor accuracy. Plus for the quick off/on output button. When switched on, the voltage rises to the set value within approx. 10ms. When switched off (no load) the voltage drops to zero in approx. 500ms. Possibility of 4-wire operation (remote voltage measurement contacts are located on the back on this green strip) but I did not play with it. The operation is quite intuitive, but it is worth starting with reading the instructions. I have not tested the functionality of the PC control. Overall, for this price (a little over PLN 500), the equipment is great.
