1.The IGBT dual-unit module medium-frequency power cabinet, by eliminating the current-limiting inductor in the thyristor inverter power supplier, is widely recognized as a highly energy-efficient medium-frequency power supply at present. It can save 5% more power consumption compared to the thyristor series power cabinet.

2. Stable operation and reliable protection. The IGBT module medium-frequency power cabinet of Huarui adopts a method where one driver board drives one module. Its reliability far exceeds that of the previous single-tube IGBT medium-frequency power cabinet. Even if there is a short circuit in the loading-end, sparking, steel threading, or water cable burning, the IGBT will not be damaged. This solves the defect of the previous similar single-tube IGBT modules breaking one after another and greatly reduces maintenance costs.

3.In terms of practicality, the equipment is quiet, durable, has strong overload capacity, has no special requirements for the usage environment, is easy to use and maintain, and has low costs.

Shandong Huarui Electric Furnace Co., Ltd. was established in 2011 in Weifang City, Shandong Province, China, close to Qingdao Port. It specializes in the production of medium-frequency power induction melting furnace systems, melting furnaces and closed-water cooling systems.
