Power-Flex uses IGBT technology to provide frequency range from 10 to 100 kHz. This power source is suitable for heat treaters that need flexibility in their heat-treating processes. Power-Flex comes in variety of power sizes ranging from 30 to 200 kW, an alternative replacement for radio frequency tube units. The 60 kW power unit gives the same result as a 100 kW RF unit without the high operating cost. Power-Flex's diagnostics makes it easy to tune and troubleshoot, and it is designed to integrate with its full line of induction scanners.
