SCR Power Supplies

Customer Satisfaction is our Business.

Heating Induction Services, Inc. is a leader in the development of high quality, cost effective induction heating systems for the Forging, Melting, Heat Treating and various other industries.

HIS systems are used and specified by OEM’s and job shops throughout the U.S. and in more than a dozen foreign countries.

The HIS “Auto-Match I” or AMI power supply line is designed to provide years of trouble free operation. Engineered with both the operator and maintenance professional in mind.

“Auto-Match I” systems feature single button operation and easy component access. Designed for the harshest environment the AMI power supply is built for Brute Power. The AMI power supply is a Current Source Inverter (SCR) system that uses a fully controlled AC rectifier to convert incoming AC voltage to a constant level of current. A DC reactor limits the change of Current flow to the Output Rectifier. The results are a highly efficient and extremely reliable power system.

The AMI series power supplies come in a wide range of frequencies and power levels, Spanning from 80 Hz up to 3 kHz and from 50 kW up to 3 Megawatts. The Auto-Match I, SCR based power supplies have proven themselves with an extensive track record of reliability and durability.
