These range of frequency converters are primarily used in Defense and Avionics applications for providing ground power for the instruments and related loads. Powertech offers Industrial Frequency Converter wide range of products to meet such application needs with specified input or output voltage and phases. The systems can be built to comply with specific customer requirements of dimensions, opera ting conditions and standard compliance. The Industrial Frequency Converter modular microprocessor based design makes it incredibly flexible and thus easy to meet almost any build requirement.

Working Principle
A frequency converter converts one alternating current with a certain frequency and voltage (e.g. 415VAC/50Hz) into another alternating current with another frequency and voltage (e.g. 115VAC/400Hz). With the converted voltage and frequency the consumer is supplied. The Power Factor Corrected rectifier converts the single or three phase mains supply into DC, the PWM inverter then switches the DC back to AC at the desired frequency and voltage, the output transformer provides Galvanic Isolation which isolates the input and output from each other.
