Induction Power Supplies

Flexitune IGBT Induction Power Supply
Versatile Induction Heating Power Supplies with Digital Intelligence

The powerful combination of advanced engineering, attention to detail and 50 years experience in induction heating has helped Radyne become world leaders in the production of medium and high-frequency induction power supplies. Our State of the Art Flexitune range of power supplies offers the user a selection of power and frequency combinations suitable for most induction heating applications. The availability of the latest IGBT power semi-conductors with faster switching characteristics has permitted Radyne to produce a new power supply ideally suited to induction heating applications from 20 to 60 kHz. The Flexitune's current source parrallel output design is ideally suited to driving high q loads.

Performance
The performance of the Flexitune Current Fed Parallel tuned-output circuit is easily matched to the work load by selecting the appropriate output tapping and amount of capacitance built into the converter to suit the required induction coil configuration. This optimization of performance allows the Flexitune to deliver full power and maximum efficiency operating at, or close to, the natural resonance of the external working circuit

Operation Operation can be by direct manual controls on the unit, Programmed via internal digital controller, from a remote control box or PLC. A built-in microcontroller provides an adjustable range of heat cycle times. NOTE: Coil Guarding must be used to safeguard Coils per NEC code . Control During converter operation, panel mounted digital meters continuously display actual power (kW), frequency (kHz), output current (I) and voltage (V). Critical running parameters are continually monitored and, if fault conditions are detected, the converter is automatically shut down. Status indication and matching assistance is provided by front panel LEDs. These signals are readily available for interface with an external host system to provide diagnostic facilities. Features • Microprocessor Controlled • Flexible operation over a wide range of heating loads • Latest IGBT technology and lower device count • Simplified power design and fully self-protecting • Simplified water cooling design • Front panel control and status indicators • Small, light, and compact Benefits • Easy tuning and setup, Provides digital measurements of Load impedance • High reliability, reduced spare part requirement • Operating conversion efficiency up to 90% • Reduced water cooling flow, accepts higher inlet temperatures • Easy to operate, install and start up Applications The Flexitune range offers improved reliability and flexible application to the widest range of induction heating duties from surface hardening through to heating. The compact design of this new range ensures that it can be easily installed into process lines or manufacturing cells, or alternatively, the converter can be integrated into the construction of a free-standing induction heating machine.
