Rapid Power Technologies has applied their 50 plus years of industry experience to the manufacture of solid state Frequency Converters. Rapid Frequency Converters are used throughout the world in a variety of applications ranging from military and industrial to marine and commercial.
 Built in accordance with individual job specifications, our Frequency Converters can be used anywhere a sine wave output of 400Hz, 415Hz, 50Hz or 60Hz is required. Our solid state design has proven an efficient and economical alternative to M-G sets or other types of inverters for a number of important reasons:
- Leading edge technology fiber optic drive circuits
- No periodic maintenance or service
- Built-in diagnostics
- Greater overload capacity- 200% of full load rated current (300% optional)
- Input/Output isolation
- Parallel operation (standard)
- High efficiency (90-95%)
- Complete quality assurance testing prior to
shipment
- NEMA industrial enclosures
Typical Applications Include:
U.S. and foreign-based manufacturers equipment testing for products
to ship worldwide.
International power conversion for individual pieces
of equipment or entire facilities.
Marinas and shipyards with international vessel
commerce.
Military operations and foreign embassies.
