Magnalenz Induction Melting Furnaces supplies Control Circuits with Thyristor Controlled Rectifier. Magnalenz Induction Melting Furnaces is an ISO 9001 awarded company. The company manufactures custom built system for Induction Furnaces. The Control Circuits with Thyristor Controlled Rectifier are not just simple diode bridge type but fully thyristor controlled. The current is limited during any failure or short circuit in the system which prevents bigger technical problems or expenses. Line Voltage Fluctuations cause no damage. Power adjustment can be done over a very large range [5%-100%]. At low input voltage the Furnaces can deliver power efficiently.
