The S series medium frequency power supplies with power ratings from 550 KW to 18000 KW and frequency range of 100 Hz to 4000 Hz have been work horses across the foundries and steel melting plants for their robust design, state of the art technology, efficiency and excellent reliability.
These power supplies adopt compact design and yet are spacious enough to facilitate easier maintenance. The inverter SCRs are well protected by break-over diodes. The current fed inverter design results in higher inverter efficiency compared to other designs. Less number of power components and component types makes the system very simple. The fast electronic tripping devices protect the system in the event of short circuits. The efficient DC Reactor ensures safety of power components.
Easy to read system monitor board provides information on systemÃ¢â¬â¢s electric parameters and for trouble shooting and maintenance. A fast acting and highly sensitive earth leak detector is provided for the optimum safety of operator and equipment.
