How do I turn off the key beep?
Press and hold the knob for a few seconds as shown to enable mute mode.
Why doesn't the power supply reach 30V?
If you are in an area where 110V is used, flip the voltage switch on the back of the power supply to 115V. Otherwise it may not reach 30V.

Out of box the input voltage selector switch was set to 220V obviously for the US market not ideal, fortunately it didn’t damage unit.If you experience lower than spec output voltage double check the switch on the back of unit make sure the correct input voltage is selected!Outside of that the power supply is accurate, usb ports are a nice touch everything works as expected & it’s a good bang for your buck!

Would be 5 stars, but any adjustments are paired with a beep, and when you're initially setting your current/voltage, it gets really annoying.Does what it's supposed to, seems decently built.

This is a nice little power supply. It has enough amps to deal with anything I've needed to power so far. Simple, straight forward controls to set Volts and Amps.Doesn't take up much space on the bench and is clean looking.

In the world of electronics, having a reliable and versatile power supply is essential for experimentation, prototyping, and testing. The recently released DC Power Supply with Encoder Adjustment has caught my attention, thanks to its impressive features and user-friendly design. After using this power supply for several weeks, I can confidently share my insights on its performance.Design and Build QualityRight out of the box, the DC Power Supply exhibits a robust build quality. The metal casing feels durable, and the compact design makes it a perfect fit for any workstation. Additionally, the clear LED display provides real-time feedback on the output voltage and current, which is a significant advantage for monitoring during operations. The encoder adjustment knob is an intuitive addition that allows for precise control over voltage and current settings, significantly enhancing user experience (Especially with my anodizing needs).Performance and FunctionalityThe power supply offers a stable output with an adjustable range, making it suitable for a variety of applications, from general electronics projects to more demanding tasks. With a maximum output of 5V at 3.6A, it provides ample power for charging USB devices and powering breadboards or development boards.One notable feature is the USB and Type-C quick-charge capability, which is a game-changer for those who frequently deal with mobile devices. This function allows for rapid charging without needing separate chargers, streamlining the process and saving space on the workbench.The addition of an Output Enable/Disable button is a thoughtful touch that enhances safety. It prevents accidental short circuits or damage caused by unexpected power surges, especially for beginners who might be experimenting with new circuits. Speaking of safety, the short circuit alarm function is a significant asset. It promptly alerts users to potential issues, allowing for timely intervention and preventing damage to both the power supply and connected components.Ease of UseSetting up the power supply is a breeze. The user interface is straightforward, and the encoder adjustment allows for rapid changes without the frustration of fiddly buttons. Whether you are a seasoned engineer or a hobbyist, the learning curve is minimal, making it accessible for all skill levels.ConclusionOverall, the DC Power Supply with Encoder Adjustment is an excellent addition to any electronics toolkit. Its combination of reliable performance, thoughtful safety features, and user-friendly design makes it a standout choice for those in need of a powerful and adaptable bench power supply. I wholeheartedly recommend this product to anyone looking to enhance their electronic projects — it’s a worthy investment that promises to streamline testing and experimentation effectively.

I have been running this power supply 24 hours a day 7 days a week since I got it. Mainly charging individual Lithium cells . These are 100 Ah cells so it takes a while at 10 amps. The power supply will go higher but I have a reason to limit the current. While charging a cell, I have been using the USP port to charge various devices while it is running. No problems. You can hear the cooling fan cycling all of the time. It is not as quiet as you might like but it isn't crazy noisy. What can you expect for this price.

Love the look and confident on brand. Works great for bench testing just keep in mind it's 5A. Fantastic clicks on under a medium load. I got the 10A version too that one handles heavy load without fan clicking on. I trust the brand had mine for over a year.
