Product Description
DIAIARY DC power supply is built by a professional team and experienced designers. The appearance is exquisite and compact for easy portability, with multi-layer safety protection. We want to provide high quality products to make our customers have a better experience in their work. It is the best choice for both professionals and beginners and amateurs.
The design of the encoder adjustment knob is different from the potentiometer knob of ordinary power supplies in the market. The encoder adjustment knob allows you to set the voltage or current more accurately and easily.
This output button is used to turn the power output on or off. You can easily adjust the voltage and current you need to set by operating the output button during the use of variable power supplies. The design effectively prevents you from damaging your load electronics by forgetting to disconnect the output. It effectively improves the efficiency of your experiments.
HD 4-digit display, status light.
The HD 4-digit LED display allows the screen to be seen clearly even in poor lighting conditions. All the working status of the lab power supply is shown in the indicator on the left side of the screen.
Mute function
The default state of variable DC power on is to turn the knob and press the button all with sound. If you like a quiet working environment, you can press the mute button to switch the mute mode.
Dual input voltage switch
This adjustable power supply comes with dual input voltages for your convenience in different areas. If your input voltage is 110V, you can turn the switch to 115V, and if your input voltage is 220V, turn the switch to 230V.
Intelligent cooling fan
The Bench power supply is equipped with an intelligent cooling fan. When the DC power supply reaches a certain temperature, the fan will automatically turn on to dissipate heat, greatly improving the life of the product.
Output voltage 0-32V adjustable Output current 0-10A adjustable Input voltage AC 115V ± 10%; AC 230V ± 10% (switchable option) Auxiliary functions Output button, OCP short-circuit protection, USB & Type-c fast charging port, silent mode
【High Precision Encoder Knob】Unlike ordinary potentiometer knobs, this DC power supply is equipped with a high precision encoder knob that has strong accuracy and stability. Pressing the knob to change the digits to the left, and rotating the knob to adjust the set voltage or current for each digit between 0-9. Make work more convenient and flexible!
【Output Switch Control】When using the DC power supply in experiments or work, the output button can prevent you from forgetting to turn off the output and causing damage to the load. Press the output button to turn on or off the output of the power supply. The status can be seen in the indicator light on the left side of the display, making it easier for you to use the bench power supply.
【Overcurrent Protection】The adjustable power supply has an OCP switch button, which allows you to select whether to turn on or off the OCP according to your work needs. When the OCP function is enabled, if the load device is short-circuited during operation, the adjustable power supply will automatically stop output and emit a buzzer to remind the user. Protect adjustable DC power supplies and loads from damage.
【4-Digit Display Screen】Variable power supply has 0-32V 0-10A high-definition display screen, which can simultaneously display three values of voltage, current, and automatically calculated power. It has constant voltage (C.V.) and constant current (C.C.) modes, which can be automatically switched. The indicator light of the working status can be seen on the display screen. The data is accurate to 0.01V and 0.001A. The high-definition digital display helps you operate as usual in the dark.
【Excellent After-sales Service】Providing high-quality products is our major commitment to our customers, and each product has been repeatedly tested. If you encounter any problems with the product you receive, you can always contact us. DIAIARY Benchtop Power Supply provides a 1-year warranty plan and online technical support.

Awesome and less usual tool to have in one’s arsenal
I’ve seen these on social media videos but never thought I’d need or use one until I got this as a gift. So far, I’ve used it four times within a month. That may not sound like a lot but when it comes in handy, it comes in handy. Aside from messing with things for fun, I’m able to verify the operability of electronics. For example, I have a battery powered light that wasn’t working. Not sure if it’s the charger, battery, or PCB controller. I was at least able to hook up the LED components, set to 5V, 1A and voila! It worked.To get the most out of it, you should know at least the basics of electricity as well as obvious safety reasons. Speaking of safety, the over current protection (OCP) feature seems to work as intended which makes me feel better. The unit allows for macro and micro adjustments for voltage and amperage. The max is somewhere around 32V and 10A which is respectable. It has a USB-A and USB-C charger for… Because why not? It comes with two leads, one for hot and one for neutral. A third for a ground would need to be procured separately. Operation is simple. The build quality seems good. It uses a standard, detachable appliance power cord which is always a plus. The display is easy to read. I have no complaints really. I plan on getting another one of these as a gift for my brother who loves to tinker.

Thrilled……kinda
Update…….I was very pleased that the supplier sent me another unit since the first one had 2 knobs missing and looked like it had been used. And about a month into using it sparingly the unit stopped working while checking a 12 vdc license plate light off my Harley. When I pulled the cover I found a fried circuit on the board. Well…..crap. and of course the warranty was gone. I put the cover back on it and checked all the functions and found that the Fast-Charge phone sockets still worked fine. I use it on my desk at work and amped up the digital volt display numbers. I charge my phone with it and you should hear the Ooo’s and ahh’s. The extra unit at home they’d sent me is still working fine months later.My DC power supply arrived in record time. But the voltage and current knobs were missing. I called Amazon, Amazon called the buyer, the buyer contacted me, the buyer sent me another unit complete with all knobs intact. I’ve never been so pleased with a buy from Amazon. Bada bing! It was handled in a matter of a couple hours. The unit has performed flawlessly, even after a battery of tests on an LED lighting system. Say what you will about Chinese businesses. They took care of me!!

Great quality little power supply for bench testing
I love it’s small size and range of power select ability.

Works as expected
Seems to work as expected. I could NOT get into system settings to change brightness of the display.Instructions say hold output button for 5 seconds. Nothing happens.Update hold voltage in for 5 second, then you can adjust brightness.

Fuse blows for no reason
I was excited to get this unit and liked its feel out of the box. The design and features too were appealing. I tuned it on an played with the current and voltage adjustments to get familiar with its operation. With no load on the unit, I pushed the output button, and the unit went dark. I found that the fuse had blown. Reading the reviews more carefully, I found that others had also experienced blown fuses for no good reason. If this happens often, it’s a pain to have to replace physical fuses. Perhaps if the unit had a circuit breaker instead, I would be more forgiving. Based on the fact that about 10% of the reviewers have found similar problems, I feel that this power supply is not reliable enough for my electronics bench, so I am returning it for a refund. Now I’m shopping for an alternative.

Great power supply for the price.
I’m powering various parts of my project and this make quick work of that task. I can quickly see how many Amps the components are consuming. This will help me plan when making the final power supply purchase for my project. Without this I would be struggling. I do recommend it.

Decent for my first bench supply
It does what it says for the most part. As one other review has noted, there is a funny behavior with the OCP that I have narrowed down on my unit a bit more:If the current (A) is set to about 0.12 to 0.14 or lower, the OCP triggers immediately when you turn on the output even if nothing is hooked up. It looks like there is some initial internal current flow in the measuring unit that triggers, you can even see it in the display for a moment before it zeros out. If you turn off OCP, turn on the output and wait for it to settle, and then turn on OCP, it is ok.This seems to not be an issue over 0.14 amps or so, which honestly is pretty small and won’t even blow up an LED, but it is a little annoying. I triggered it only because I was practicing Ohm’s law, doing the math, and wanted to see if I nailed it, so I had the OCP tolerance set really tight. (I’m *very* new to building circuits)Other than that, it seems to be a very useful and reasonably priced tool.

It is exactly what this product is all about. It is a power supply and I realize I could not use it to verify ohms..I use it for testing LEDS and other power sources. It could have been able to generate more watts. Limited display of digits. 3.5 digit display.
