What it does
100 KVA rotary frequency converter system, type approved by DQA(N)
A rotary frequency converter turns supply at one frequency into supply at another through a motor and an alternator on a common shaft. Where an electronic converter injects harmonics and fails hard, a rotary machine isolates the load mechanically and rides through disturbance, which is why naval installations still specify them.
Leo holds the type approval for this system and supplies it as a whole: the converter, its control panel and its remote panel, with the specification, integration, type test coordination and support that come with a defence supply. The certificate names Vijay Electric Power (I) Pvt Ltd of Bengaluru as the original equipment manufacturer, and this page names them too, because the certificate is the first document a buyer reads.
Ratings and configurations are built to the requirement rather than to a catalogue.
