These Converters find applications in Defense, Avionics as well in industries. Normally the requirements will be for systems with 50Hz as input and output frequency being variable over a range, typically 40Hz to 60Hz or 300Hz to 800 Hz with constant voltage or voltage also as a variable. Dubas offers wide range of products to meet such application needs with specified input and output voltage and phases. The systems can be built to comply with specific customer requirements of dimensions, operating conditions and standard compliances.
