To many, finding affordable, high-quality products made in USA seems to be a thing of the past.  Many folks are so accustomed to living with poor quality products that they have forgotten what it was like when quality products could be purchased in the USA and supported here as well.  When it comes to voltage and frequency conversion, the wait is over, thanks to KCC Scientific products.   There are several factors to consider when you have a choice between an import-quality voltage and frequency converter and a Made in USA converter.  Let’s review a few of them.

Expert Advice: Do you need help solving a power problem with your electronic device? If so, whom are you going to call?  If you call us at KCC Scientific LLC, you will get expert advice from one of our engineers.  And, we understand the vast majority of devices that require voltage and frequency converters and can usually solve your problem for you.  If we do not have what your device requires, we will recommend someone who does. 

Precision: What precision does your device require? There are no import-quality frequency converters available with 0.0002% frequency accuracy.  Yet, chances are the electronic device you are trying to power requires this level of precision (this is often overlooked—don’t be surprised!).  In addition, KCC Scientific LLC converters reconstruct the mains power line completely, so your device is sure to have clean power.  This is rarely—if ever—the case with import-quality devices.

Safety: What is the quality of the device you are purchasing? Are you sure your device will not overheat, burn, grind or shut down? Made in USA frequency and voltage converters from KCC Scientific LLC are rugged, reliable and built with safety in mind.  You would be surprised how many calls we get from folks who have tried an import-quality converter, only to have it overheat, smoke or burn!

Returns:  Sometimes the device you are trying to power is missing its rating tag, or the power specification is not available.  If you purchase the wrong converter can you return it for the correct one? KCC Scientific LLC offers assistance in choosing the right converter, but also offers a two-year warranty and help if you need to upgrade your converter to a higher power unit.

Tariffs: What are the tariffs for purchasing an import?  These days tariffs are attached to your purchase, often after the fact.   Be aware you may not even know how much the tariff is until it hits your credit card.  Buyer beware!

We at KCC Scientific LLC have been designing and manufacturing compact, low cost, precision voltage and frequency converters in the USA since before 2011. If you need assistance to solve your power problem contact us here:  About Us or give us a call.  Yes, we will answer the phone and are ready to assist you!  Call toll free at 1-833-502-6049.

Now, for a few tips to help you:

When it comes to converting power for electronic devices around the world, there are a few options. Selecting the right converter is dependent on what electronic device you are powering and why.

What Power Converter Do I Need?

Do I need just an adapter plug, a transformer, or a voltage and frequency converter? Let’s take a look.

Adapter plugs are what connects into the wall or mains power line from your electronic device. When added onto the end of your power cord, it changes the shape and prongs of the plug to match the outlet, in the country you reside. If you have a universal electronic device, you may only need an adapter plug. A universal device is one that is enabled to power up and operate properly on 90-250 volts AC as well as 50Hz and 60Hz frequencies. To check to see what adapter plug you may need for your electronics, click here:

Transformers change the voltage, and only the voltage. If your device requires 115 volts AC and you are residing in a country that has a mains power of 230 volts AC, you will need a transformer to step down the 230 volts to 115 volts AC. The opposite holds true as well. If you are in a country with a 115-volt AC grid and have a device designed for a 230 volts AC, you will need a step up transformer. Again, check the world standards website, to see the voltage by country.   You will also need to check what level of power your electronic device requires.  This is critical to selection of the proper transformer.  The power required by the device you are attempting to power will be designated in Watts, often found on a tag or the back of the device.

If you decide you need only a transformer, be aware that not all transformers are created equal. We strongly advise you to avoid cheap import-quality devices, which are often under-designed resulting in overheating. Some are built with low-quality laminated core transformers and can emit a very annoying buzz. Please refer to our blog which relates Mary’s experience with one of these perilous devices.

Frequency Converters are needed most often when the electronic device has a synchronous motor that turns or vibrates.  Then, the device is dependent on the mains frequency to assure that the motor operating at the proper rotation or speed.  This speed will depend directly on the mains frequency that it is connected to.  Most likely if you need to change the frequency, you also need to change the voltage. Thus your device will usually require a voltage AND frequency converter.  But then, some 60Hz device transformers don’t do well when operated at 50Hz and could overheat.  It isn’t always a speed issue.  Operating at the wrong frequency can also create reliability issues.

What to Consider When Buying a Power Converter

Consider these tips when purchasing a voltage and frequency converter.

  • How much power does the electronic device require? The power will be designated in Watts, often found on a tag or the back of the device. If it has a lower power requirement you may not want to pay for an oversized converter. Only pay for what you need. A higher power converter can be used on a lower power device but not the reverse.  Be aware of what power your device needs.
  • How much accuracy does my electronic device require to operate well?  Import-quality converters are made as mass-market devices and are not generally designed for quality. For delicate devices, import-quality converters are simply not precise enough–not even close.  We’ve measured some that were 20% off.
  • How large is the converter? Will the converter fit where it physically needs to be in order to power your electronic device without being obtrusive?  Size matters.
  • How much does the converter weigh?  If you are traveling with electronic devices for global work, you may want something compact and lightweight.  To compare frequency converters and features, click here:
