Product Description

The DC power supply is a professional power regulation device that features a clear, backlit four-digit LED display that allows you to see the 00 is the precise accuracy. The values of 01V and 0 are equivalent. The tuner can be easily adjusted from 0 to 30V and from 0 to 6A.

The easy-to-use knob of fine and coarse makes it possible to adjust the data of voltage and current digit by digit, allowing for the quick and easy setting of the desired output resolution As well as a pure copper toroidal transformer, a temperature-controlled fan, and a unique solar heat dissipation system, the unit also comes with a 4-in-1 power supply, divided into universal, digital, programmable, and timing outputs.

Five powerful protection functions are provided by the Power Supply, including over-voltage, over-current, over-power, over-heat, and short circuit. This product contains a small, integrated fan that produces low arc noise and low ripple, thereby extending its life significantly. Also, the voltage, current, and power of the power supply are all displayed at the same time, and the keyboard can be locked to prevent accidental operation.

Dr. meter 30V/6A power supply includes a big fan controlled by Smart Temperature Control in addition to multiple heat radiation grooves on the side, so it is able to quickly disperse heat during operation, increasing its efficiency and lifespan significantly!

Designed for laboratories, schools, and production lines, this adjustable DC power supply offers 30V 6A of power. The output voltage and output current can be continuously regulated between zero and nominal values. In this device, voltage and current are precisely located and a double potentiometer adjustment can be made. This product has good power stability and ripple coefficient, and is able to sense voltage and current with a high degree of accuracy.

Questions & Answers

What is the impact of the 'noise' spoken of by switching (vs linear) power supplies on human hearing? Are pet ears noticeably different from human ?

In fact, you only see it when you do rf stuff with it, or you hook it up to an oscilloscope so you can see the noise.

The instructions state that you must short between the positive and negative terminals to set the maximum current. Is that really what you're doing?

In short, yes. As with any CC limit adjustment for a supply that has this feature, we would typically do it this way.

How does this display output current or is it just the current maximum settings and wattage?

In this graph, the current that is currently leaving the supply is shown. In order to set a limit on the current value (CC) The output should be shorted while you are disconnected from the load. After doing this, you can adjust the current setting up or down, and that value will appear. In order to connect the two outputs, you must disconnect them from each other, and then you must connect them to whatever is your load. On the display, you can see the current, voltage, and wattage delivered to the load.

Does this mean this is not a floating power supply?

Neither the input power cable's ground connection (or "OSHA Ground") nor the output cable's ground connection is connected. Depending on the situation, this can be configured as a negative supply.

The price is fair for the quality of the product

5/5

My overall opinion of the product is a decent one. I'm a hobby electronics enthusiast, so this is a big welcome to my.

Here's my idea on how I would create one

5/5

Before we get started, let me clear up one thing. There is no remote sensing, and since it appears that they take the feedback from the circuit board rather than directly from the terminals, the load regulation is not perfect. My testing showed that it was a little below 20mV/Amp, but I didn't check every spot. The new one is much better than the analog one it replaced. Not perfect, but certainly better than the analog model. I know, but that's what the form says- It cannot be a con, because it is not a factor. There is no visible wiring on the unit, which is about 12 inches long and weighs about the same as The circuit board looked really well laid out, the solder looked neat and well tied to the chassis and heat sink. I didn't pull it apart but through the vent holes it looked good. As far as testing to 5A is concerned, it delivered It does not make any of the noises that switchers can make when pushed, such as hums or buzzes. It was an open circuit, the voltmeter was within the last digit, and the current meter was up to the 2nd digit on the voltmeter. The fuse on the precision meter is set to 3 (75A). Then, after testing at 5A, a couple power resistors were connected to make sure it read 10W. This was tested two times with the same result the voltage and current were unchanged for 8+ hours once the resistors had stabilized. And the fan did not run either time. During test runs, the temperature did not rise above 80 C. With my 40 years of experience as an analog tech, I can tell you that I know what I'm doing. I am always surprised by how some companies develop products with technology on par with Star War levels but neglect the basic technical support. Circuit boards that are poorly designed or assembled are my biggest pet peeve. The one you are looking for is not I think the design is excellent, and it's well thought out in its small details. Adding a new bench to my collection was a nice addition.

Power supply is a little on the small side

3/5

The bottom line It has always been a dream of mine to have a power supply to tinker with since I was a college student. We have arrived at the right time! The purpose of this experiment was to discover if an 18650 battery with a defective lithium ion could be reversed by applying a controlled *Brenda - Recommendations You must read and understand the instructions for setting Constant Current mode (if you require such a Pulling off the knobs, I marked the center point with a Sharpie marker. I reassembled the knobs with the center point marked The pros are Fit is decent and it's comfortable The finish line. The cons are a) It is possible to fine-tune the CV and CC With CC, the voltage knobs (coarse and fine) need to be turned fully clockwise (max), then the current dial needs to be adjusted. 4) Knobs DO NOT have symbols. 2) The wire lead included is thin (small gauge), and all connections are The conclusion is The price is $60, so we rate it a 3 A five-star rating. It's a pretty handy little power supply for DIYers!.

Power supply with a nice DC output

5/5

Despite being so inexpensive, this power supply is pretty well constructed. The housing is all metal, the switches are good quality, and it is small and compact in size. The fan is reasonable quiet, and it appears to work well. In addition to just dabbling in electronics as a hobby, this is my first power supply, but its price and quality are a good fit for just an enthusiast. It will add a great deal.

It is important to have a reliable power supply

5/5

The small 9 V power supply was no longer sufficient for my projects because I got to the point where it was too hot. A power supply with an affordable price was what I was seeking. On the attached images, you can see that I tested the voltages and it worked fine. In terms of voltage, I got a max of There are only 7 VRAMs and this is perfectly acceptable since we are not talking about a device that has hundreds of dollars in it. Additionally, my DMM is also not a high-tech brand, so it is also possible that errors are produced there. As long as the project is a DYI project, it is acceptable to In my home office I do not need expensive setup.
I'm happy that I have it on my desk and that it is worth its price.

My application is perfect Despite its low cost, it is well rated in terms of power

5/5

Despite this unit's light weight and ease of use, I find it to be very convenient. I think it is a really good performer for the price. Breadboarding and driving prototype circuits on my bench are some of the things I use it for. The detail of my load / ripple / noise test will depend on the amount of lab equipment I can easily access after I clean more of my lab!.
