Review on 💡 Kungber Lab DC Power Supply Variable: 30V 5A Adjustable Switching Regulated Bench Power Supply with LED Display and USB Interface - Coarse/Fine Adjustment & Alligator Leads Included by Kenny Hrdlicka

Summary: This power supply appears to be designed for hobbyists. It aims to provide basic functionality (don't expect any frills) at a lower price point than many power supplies. For the most part it succeeds. The controls need some work to make this device more user-friendly. So it's a smart option if you're willing to be patient with the controls for a cheaper power source. If they fixed the controller issues, this would be an absolutely perfect entry-level power supply. Recommendation: If you are a hobbyist who needs an affordable regulated power supply and you mainly work with a few voltages, this power supply might be a good fit for you. If you need to change voltage frequently, this power supply may not be for you. Pros: Stylish, not just another beige bank box; affordable and buy only the voltage and power you need; compact and light; Voltage and gain controls front and center. Separate coarse and fine adjustments (tuning should be easy but not much in practice see bad). output power, making adjustment difficult. The fine adjustment knob has hard stops at minimum and maximum that limit its use. A: I really can't say enough about the style. My other PSU looks very outdated in comparison. The power supply provides accurate voltage and current readings. And this is the most important feature of the power supply. I've never been a fan of putting power switches on the back of devices. I hate reaching out and blindly seeking control. While I would have preferred the switch to be on the front as this is an entry level device and the switch is easy to find, I don't see this as a real issue with this device. This device can actually use "exit". Button to turn off power to banana plugs during power adjustment. This is a good practice to avoid accidentally overloading the device you are powering. Without an exit button, you'll have to unplug the cables from your device while making changes. I also like the front and center front and center voltage and amp controls that work right out of the box. With my other power supply, changing the power settings forces you to push buttons and turn dials so much that any simple power adjustment feels like trying to fly a Boeing 747. A product that can change voltage faster would be very welcome. However, the controls need to be improved. . If you dial the voltage down, the output voltage adjusts very slowly. In fact, you can turn the tension down, let go of the controller, and sit back and watch the tension drop further. (The delay does not occur when the voltage is increased.) However, a potentially more serious problem is the hard stops on the fine adjustment knobs. You can turn the knob clockwise or counterclockwise only as far as it will go. This means that the fine adjustment knobs are only useful within a limited range. You must ensure that the course correction is within this limited range in order to be able to reach the target by making the final correction with the fine knob. Given the controls' limitations, I recommend the following procedure for setting your values. Disconnect the power cords from your device. - Turn the fine adjustment knob all the way to the left (counterclockwise). Set the voltage slightly lower than your target value - Turn the fine adjustment knob to the right (clockwise) to get the final target value - Reconnect the power cords to your device.
