Product description: Korad KA3005DS 0-30V 5A laboratory power supply

A laboratory power supply , next to a digital multimeter and a soldering station, is one of the most necessary tools in an electronics workshop. Such a power supply supplies the voltage necessary to power electronic systems during their prototyping and servicing. KA3005DS is a stabilized laboratory power supply with programmable memory and smooth voltage regulation in the range from 0 V to 30 V and current up to 5 A. It has an accuracy of intensity indications up to 3 decimal places . The design of the power supply is based on a transformer, and a large, clear LED display provides current information about the current voltage and load.

Korad KA3005DS laboratory power supply 0-30 V 5 A.
The Korad KA3005DS laboratory power supply has short circuit and overload protection.

A perfect deal. Super machine. Fast delivery

The power supply is easy to use, of good quality, and most importantly, compact. A handle for carrying would be useful. My friend has had one for several years, uses it frequently, and it still works. That's why I bought the same one for myself.

Fast shipping, as described, everything works as it should be. I recommend

Good power supply, good price; It copes well with the "stresses" that are inevitable. Also for beginners; Many of them (except for those who give up) will buy it after a short time anyway.
Sławomir 06.03.2026 Confirmed purchase Translated review
Very good bench linear power supply! I have not found a better one in this money.
sławomir 24.02.2026 Confirmed purchase Translated review
The most important thing is that it is linear and does not create interference. Safe for running sensitive systems.
Dariusz 20.02.2026 Confirmed purchase Translated review
A sensational linear transformer power supply in this price group. In addition to the main switch, there is an additional button that feeds power to the banana sockets, which allows you to set the power parameters in advance. From switching on, the voltage smoothly increases to the set value in about 15ms and in a similar time it decreases the voltage in the event of exceeding the current value or switching off. It is important that the set voltage does not spike above the set range, even when the main switch is turned off. Easy changes of current or voltage during operation (we choose the amount by which we will change and turn the knob). Choosing a different position from the memory always turns off the power, so we won't burn anything by mistake. I was pleasantly surprised by the voltage measurements that I made with a calibrated meter. I set 5 V, the measurement is 5,001 V and for 25 V the measurement is 25,005 V. My oscilloscope did not register noise and pins as in not much cheaper switching power supplies. Definitely a cost-effective purchase that completely changes the comfort of work and allows you to discover the secrets of electronics. In addition, the quality-to-price ratio is very favorable. I definitely recommend it, and even encourage and persuade it. No more burned-out LEDs, problems with radio or GSM communication caused by interference. Ideal power supply for prototypes, IoT, RPi, Arduino and all kinds of modules. 🚀

The power supply is very recommendable. Service sales and shipping efficiently and quickly. Recommend
Zdeněk 30.09.2025 Confirmed purchase Translated review
For 1700 excellent 30V 5A power of small dimensions, linear, 5xmemory, the advantage is switching the output voltage at which there is not such a large voltage spike, overcurrent protection can be used to charge the battery. The disadvantage is the noise of the fan, and the piece you just bought is noisier than the power supplies used at work. A clear choice👍️ compared to the competition
Luděk 28.08.2025 Confirmed purchase Translated review
Perfect just what I needed 👍️
Wojciech 20.08.2025 Confirmed purchase Translated review
After buying it, the price of the power supply has dropped on your website by about 20%, I'm not happy about it because I feel like I overpaid for this product.
Andrzej 12.08.2025 Confirmed purchase Translated review
Excellent value for money
Per 21.07.2025 Confirmed purchase
Korad KA3005DS is a good device, heavy which shows that it is made with care. The only thing I would like would be continuous voltage adjustment, which is in all analog devices. Now you have to go through off/on time when changing the voltage when searching for threshold voltages. A small annoyance that does not make the device impractical, it just slows it down a little.

Hello. Very fast shipping, personal thanks to all the store staff !! Digitally controlled transformer power supply protections work perfectly, you will not burn any diode or circuit after setting the protections at that time. Thank you and Merry Christmas to everyone PS : I recommend the Botland store !!

All OK
Heinz-Werner 05.12.2024 Confirmed purchase Translated review
The price/performance ratio of this device is very good! I had several predecessors of this device that were also good, and some things have been improved here on this device, e.g. the fan control, and a power indicator has been added. Can fully recommend this lab power supply. 👍️👍️👍️
