Everything You Need To Know To Find The Best Direct Current Rectifier manufacturer

What is a Rectifier?

A rectifier is an electrical device used to convert alternating current (AC) into direct current (DC) by allowing a current to flow through the device in one direction only. Diodes work like one-way valves within the rectifier to maintain this flow of current. This process is generally known as &#;rectification.&#;

While rectifiers have many uses, they are most often used as the primary components of DC power supplies and high-voltage direct current transmission systems. In an industrial setting, rectifiers are typically spec&#;d based on voltage applied, current needed in the process, quality of the power, and how the control will be arranged.

Ripple is an important measurement for determining the efficiency and quality of a rectifier. Ripple is the clarity of the power (how clean it is) expressed in a percentage. AC divided by DC equals the percent of ripple.

Since our founding in , Dynapower has been at the forefront of the development of custom and standard rectifier solutions for metal finishing, mining, steel, chemical, defense, and hydrogen production industries worldwide.

Types of Rectifiers

There are a wide variety of industrial rectifiers, including SCR, powerstat, tapswitch, switch mode, IGBT chopper, and thyristor rectifiers. Tapswitch and powerstat rectifiers offer little to no control for operators. They have a very low ripple reading, low amperage, and low cost, yet they are typically very expensive to repair.

Alternatively, SCR, SMPS, and IGBT chopper rectifiers offer seemingly infinite control for operators; they can easily control voltage from top to bottom between zero and 100 percent.

SCR Rectifiers

An SCR rectifier is a semiconductor power supply that meters electricity by opening electrical &#;valves&#; that work together to rectify electricity. The longer the &#;valve&#; is open, the higher the voltage leaving the rectifier will be.

Dynapower RapidX Series SCR Rectifier

SCR rectifiers are variable voltage DC power supplies that are low frequency, high ripple systems. These systems are rugged and have a history of durability in the market&#; a number of our customers have systems still running after 40 or 50 years. They regulate and react steadily, carry a lot of power in large copper windings, and are fairly easy to troubleshoot with large, easy-to-identify components.

Switch Mode Power Supplies

A switch mode power supply (SMPS) is an electronic power supply that uses a switch from AC to DC, back to AC, then once again back to DC. This is all done at high frequency allowing for the internal parts to be smaller. They utilize a high primary voltage&#;where 480VAC input units typically see 700VDC&#;switching voltages inside the transformer.

With smaller parts, tighter windings, smaller footprints, and an even tinier tolerance, these precision pieces of equipment offer good space efficiency per watt, modern computer interfaces, and intuitive controls.

Switch mode power supplies have been around for roughly 40 years. Traditionally, these were used in smaller current applications and only in the last 10 years or so have large-scale switch modes been successfully deployed.

Rectifier Cooling Options

Rectifiers can be air cooled, water cooled, oil cooled or hybrid cooled. Traditionally, most rectifier manufacturers offer air or water cooled rectifiers. Air cooled units are typically larger per watt of power because they need more surface area to dissipate the heat, while water cooled units are typically smaller because surface area is not a factor in cooling these units.

Rectifier Maintenance

Although extremely durable and long-lasting, rectifiers do occasionally need repairs. The majority of rectifier issues are caused by the overheating of electrical components, like a circuit board. The root cause of overheating could be corrosion, bad cooling lines, a wrong component put in during a repair, breakdown of organic varnish in the transformer, or poor bussing connections.

Good heat management is important for long-term rectifier maintenance. The general rule of thumb to minimize heat is: clean, flat, and tight:

1. Keep all contacts clean.
2. Ensure all electrical surfaces are mounted flat to one another.
3. All electrical surfaces must be tight.

Are you looking for an electroforming rectifier? If so, chances are you have a lot of questions. One of them probably is &#;how do I choose the best rectifier for electroforming?&#;. It&#;s a legit question, and one I asked myself when I first started electroforming. But don&#;t worry, choosing the right rectifier doesn&#;t have to be a daunting task. In this post, I answer all the questions you might have about power supplies, and I included a buying guide to help you choose the best rectifier for electroforming.

Why do I need a rectifier for electroforming

A rectifier is probably the first thing you should get if you intend to electroform or electroplate an object. Without a rectifier, you won&#;t be able to provide the electricity needed to plate your creation.

Basically, rectifiers convert AC (alternative current) to DC (direct current). For electroforming, you need a steady direct current to obtain a good plating.

Rectifiers come in all shapes and sizes. If you&#;re a beginner you can get a simple, easy to use power supply. You don&#;t need it to be very powerful since you are using it on very low voltage for electroforming. 

How do you use a rectifier for electroforming

You&#;ll definitely get better results if you know how to properly use your rectifier for electroforming. First, you need to attach your negative clip to the object you wish to electroform and positive to the anode. Then, you need to figure out the right voltage for your project. This is an important part of the electroforming process. To know the exact voltage you need to plate your piece, you have to calculate the square inch of the surface area you want to electroform. It can be done using this tool. You&#;ll be setting your amps at 0.1 amps per square inch of surface area. In other words, if you want to plate 5 inches of surface area, you&#;ll be setting your rectifier to 0.5 amps.

Once your rectifier is turned on and set on the voltage of your choice, you&#;ll notice a slow build-up of metal on your piece. If you use high current, your piece will become grainy. This can be interesting if you wish to have texture on your creations. However, for a smooth result, a low voltage is always best. You&#;ll have to check your piece periodically and make adjustments (turn the power up or down) until you obtain the desired texture. I leave my pendants at least 8 hours in the bath &#; but more often 15-24 hours. 

How to choose the best electroforming rectifier

 

If you&#;ve never bought a rectifier before, you probably don&#;t know what you should be looking for. You don&#;t wanna buy just any power supply and end up with something that&#;s not going to work for electroforming. So, here is how to choose the best electroforming rectifier.

• Type of rectifier

You want your rectifier to be a DC power supply. It&#;s very important because direct current is what you need to plate your objects. Also, choose a rectifier that is adjustable and accurate, because you need to adjust your voltage precisely to get the wanted result. 

• Price

I personally think you do not need to buy a very expensive power supply, especially if you&#;re a beginner. You want your rectifier to last though, so I don&#;t recommend buying the first price either. If like me, you&#;re only using your power supply for electroforming, I suggest getting a rectifier between $50 and $100.

• Size and weight

Don&#;t forget to check the size and weight of your rectifier before you buy it. Especially if you have a small space to establish your setup. Most rectifiers are quite small and lightweight. They are easily portable and can be stored in any cupboard. I like that about mine, and I wouldn&#;t want to be bothered with a big machine.

• Power

If you plan on electroforming dozens of pieces at once, you might want to consider buying a powerful rectifier. Mine is 30V/5A and I plate up to 3 pieces at once with it. I&#;m sure you can do a lot more though. If you have a big bath, you might want to consider getting a 30V/10A power supply.

• Ease of use

I had no idea how to use a rectifier before I got one. But since most of them come with instruction manuals, it&#;s not too hard to set up. However, I recommend checking reviews that mention the ease of use before buying. 

Electroforming rectifier: Buying guide

Here is a list of some pretty good electroforming rectifiers for beginners. I just want to mention that the power supplies I recommend are best for &#;hobbyists&#; or people like me, who enjoy making jewelry and selling it online. I do not mass produce, I plate around 10 pieces per week &#; sometimes less. If you want to plate hundreds of pieces at once and produce high volumes of electroformed objects, you might want to look at more powerful and more expensive rectifiers. With that being said, here are the best electroforming rectifiers for beginners:

The Eventek DC power supply is the one I&#;m currently using. It&#;s adjustable and can provide power up to 30V/5A. With this, you can easily electroform several pieces at once &#; I always electroform 3 at a time. This power supply is very accurate, and reliable. On top of that, it&#;s pretty affordable, small, and lightweight so it won&#;t take too much space in your home. Safe to use, this rectifier is FCC certified. Also, it has voltage overload protection and hot-circuit protection, so you don&#;t have to worry about using it for long periods of time. It&#;s super easy to use and comes with alligator clips. However, they are super small, but you can just get another pair if this is a problem for you. The Eventek DC power supply is definitely one of the best rectifiers for beginner electroformers.

The only drawback of this rectifier is that it is a little bit bigger than the others I recommend. If you have a lot of space, it won&#;t be a problem for you though. If you want to get a rectifier that provides more than 5A of power, this one is your best option. 

Benefits

&#; Good value for money

&#; Powerful

&#; High accuracy

Drawbacks

&#; It&#;s quite big

Bottom line

Choosing the best rectifier for electroforming is easy once you know what you&#;re looking for. Make sure you are getting a DC power supply that&#;s easy to use. If you&#;re a beginner, you can easily find a great rectifier for less than $100. Out of the 5 power supplies I recommend, I personally used 2 (#1 and #2). The others made it on the list because I know artists who use them. Either way, they all are suitable for electroforming. Just choose the power supply you feel will be the best for your projects.
