Power supplies
General Information
Interpower Induction power supply units run on a wide range of frequencies, 50hZ to 250 kHz. They are designed to operate in the harshest of environments and will provide long-term, trouble-free operation.
The power transistor, called Insulated Gate Bi-Polar Transistor (IGBT ) allows absolute turn-on and turn-off even at high operating frequencies. The ability to turn off these devices at any time during the operating cycle makes this one of the most reliable systems on the market today. This technology allows for power, voltage, or current control. The power supply can run over a wide range of frequencies set by the configuration of the heat station. Interpower’s power supplies consist of the units along with a line disconnect switch, power components, solid-state controls, all operator controls, and safety devices.
- IGBT power operates at a range of frequencies with fewer coils and lower energy costs
- Solid-state units have advanced power and electronic controls
- Designed to perform in harsh environments with long term, trouble free operation
