WHATEVER QUESTIONS YOU MIGHT HAVE, WE CAN HELP
At Visicomm Industries, we have various solid-state design and rotary design frequency converters to choose from. We want to ensure you’re fully satisfied with your unit, which is why you can come to us with any questions.
There are several factors to consider when choosing a frequency converter unit. Whether you need assistance selecting a size or determining if you need a solid-state design or rotary design frequency converter, you can rely on our group of experts. Give us a call, or fill out our contact form, and we’ll help you select exactly what you need. Thanks to the Job Satisfaction clause in our warranty, any unit you purchase from us will get the job done and done well, guaranteed.

WHEN DETERMINING YOUR NEEDS, YOU MAY BE ASKING YOURSELF:

• What size unit do I need?
• Which design is best for my application?
• Do I need Rotary Design?
• Does my application require Solid State Design?

For all your facility’s power needs, you can rely on Visicomm Industries, a world leader in frequency converter manufacturing. Our solid-state frequency converters are of the highest quality in terms of both construction and safety and come in various dimensions, weights, inputs, and outputs, so you can choose the unit that best suits your specific application. To learn more about our static frequency convertors, read below for details regarding their construction and specifications.

SOLID STATE FREQUENCY CONVERTER CONSTRUCTION

1 TO 12 KVA

• Solid state transistorized compact enclosure less than 60DbA at 3ft. – any single phase input, any single phase output – any input frequency, and 50Hz, 60Hz, or 400Hz output. All of our products are available for purchase, monthly rental, or lease to purchase. Our frequency converters are 60hz to 50hz output, switchable. 400Hz output is also available (see below).
• All solid-state frequency converter units can be furnished with an optional battery backup in a separate plug-in enclosure at additional cost.
• Perhaps the best way to illustrate the functional versatility of our units is to start with a rearview photo showing the typical controls and connection terminals. Scan down to read the input and output information for our static frequency converters.

ROTARY CONSTRUCTION – – 6 TO 2000 KVA
A brushless motor and generator are mounted side-by-side (vertical one atop another to minimize footprint is an option) on a welded steel frame skid. This design (as opposed to solid state full sine wave design) is recommended because:

• Rotary frequency converters are inherently less expensive for 3 phase units 12KVA or larger. A similarly rated unit would be about 50% higher in price and, because of the comparatively limited motor starting capability of solid-state designs, a unit with the same motor starting surge rating would be about twice as expensive.
• Rotary Design is easier to repair in the field and has far fewer components that are subject to failure and subsequent search for replacements that are no longer made. Any fair-sized city worldwide has a motor repair shop capable of repairing rotary units and electric motors are commonly many years old before the repair shops see them. Should the occasion ever arise, we have our own list of authorized repair shops, and 1 or 2-day turnaround is the rule. Many rotary frequency converters still running in the field are 25 years old or more.
• Rotary frequency converters are more rugged and flexible in the loads they can handle aside from greater motor starting surge capacity. For example, SCR loads and welders are almost insurmountable problems when using a solid-state approach.
