High Frequency Induction Heating & Power Supplies

Model LFI / HFI Series Induction Power Supplies

High Frequency Induction HeatingThe LFI and HFI series of power supplies offer a wide range of frequencies (LFI-35-100 kHz and HFI-135-400 kHz) in power from 3.0 to 100 kW, which correlates to technical effectiveness in a variety of customer applications. Designed with an adjustable tank capacitance and multi-tap output transformer, the LFI/HFI systems are flexible and reliable to meet your most demanding manufacturing conditions. 

High-Frequency Induction Heating Model Features:

  • Modern Compact Design: suitable for a wide range of applications with its rugged, reliable construction. It meets demanding conditions imposed by high production processes
  • Systems are rated for 100% Duty Cycles
  • Highly Efficient MOSFET based Solid State Circuitry
  • Broad frequency range; 35-110 kHz (LFI) and 135-400 kHz (HFI)
  • Trouble free tuning to a variety of loads
  • Remote Interface with 0-5V and/or 4-20mA input
  • Input cooling water to 105°F
  • Power Supply Range from 3kW to 120kW Output Power
  • Standard User Interface for connection with external devices (PCL) monitoring and automation integration
  • User programming allows user to set up to 12 separate jobs with up to 25 steps per job

Diagnostic Systems & Meter Displays

All RDO Induction Model LFI/HFI Induction Heating Systems are equipped with Diagnostic Limit Indicators for Voltage, Power, Frequency and Current, along with Trip Indicators for Frequency, Current, Over Temperature, Door/Cabinet Interlock and Water pressure. These indicators are located on the front panel for ease of diagnostic control. All RDO Induction Model LFI/HFI Induction Heating Systems are also equipped with a full scale Meter Display, which allows the user to monitor Power Output, Voltage, Frequency and Current.

Heating applications for the RDO Induction LFI/HFI family of power supplies include Induction Brazing, Induction Soldering, Hardening, Induction Annealing, Induction Bonding, Induction Case hardening, Induction Wire & Cable processing, Getter Firing, Hot Heading/Forming, Induction Shrink Fitting, Catheter Tipping and Induction Stress Relieving.
