THYRISTOR FREQUENCY CONVERTERS

Purpose

The TFC series frequency converter for induction heating and metal- melting devices is designed to work in electrothermal heating systems and can be used as either a standalone device in the metal heating and melting process or as an integrated device as a part of technological systems. The main feature of thyristor converters is high reliability, wide power range and relatively high output voltage.

Main advantages

High efficiency and no idling losses can reduce power consumption by 10−15% compared to rotating converters. The lack of moving parts ensures low maintenance expenses and an at least 30-yearlife span without major overhaul. Double- sided construction ensures simple and comfortable maintenance.

Output characteristics

Wide range of the output voltage: 20−100% of the nominal value; range of output power is 3−100% of the nominal value. Adjustment of output parameters without switching in power circuits eliminates the need to use the cumbersome switching devices.

Microprocessor control system

6th generation TFC series generators are equipped with a modern microprocessor control system which:

• extends the functionality of the converter;
• increases reliability;
• simplifies commissioning;
• Device status information is shown on the displays of control panel
