GH Induction Atmospheres Introduces New Induction Heating Power Supplies with Wide Frequency Range

GH Induction Atmospheres, part of the worldwide GH Group, has introduced a new series of 13 induction heating power supplies with a wide frequency range for increased flexibility. The SM Type Transithermic® power supplies cover 0.5 to 20kHz with 100 to 800kW output power; 100kW output is available over the extended frequency range of 20 to 150 kHz.

With up to 90% efficiency, high reliability, and easy-to-use digital control, the SM type power supplies are well suited for both new installations and existing systems. "With the flexibility provided by the extended operating range," reports GH IA General Manager Steve Skewes, "SM type power supplies will be quite popular as replacement power sources for many existing industrial heat treating machines."

SM type power supplies features a modular design with plug-in power control cards. The power supplies utilize IGBT transistors and include a DCP (Digital Control Panel) with built-in diagnostics and optional kW/sec. monitoring. A series oscillating circuit offers high efficiency and easy load matching. GH transithermic power supplies can operate at variable frequencies; the frequency is automatically coupled to the load, in every application, within a wide range.
