1.2 kW - 5kW Induction Heaters

Flex Heat Series Induction Power Supplies

FlexHeat Compact for Induction Heating

The RDO Induction Flex Heat Induction power supplies consist of our S-Series (1.2kW-5kW – 50-kHz-250kHz), The Flex Heat systems are built with the latest in solid-state electronics to ensure maximum output efficiency and highly consistent output. The 1.2kW, 2.0kW and 5kW Flex Heat systems are equipped with a One-Touch Auto-Tuning feature, which will automatically find the resonant frequency that the load coil will use.

With the Flex Heat series induction power supplies you can add up to 10’ feet of Flex Leads for remote heating with a coil that can be handheld or easily integrated into an automated production cell. A switching station is also available, in the event the user wants to set up two separate heat stations that could be alternated by setting a switch for the A or B Station.
