TFD Induction Power Supply

The TFD induction power supply is the second generation of transistorized power supplies.

Optimized for performance

The performance of the TFD induction power supply series tuned output circuit is easily matched to the working 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 TFD to deliver full power and maximum efficiency operating at, or close to, the natural resonance of the external working circuit. During converter operation, panel mounted digital meters continuously display power (kW), frequency (kHz), output current and voltage.

Critical running parameters are continually monitored, and if fault conditions are detected, the converter automatically shuts 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.

Robust Design is Criticaltfd induction power supply

The TFD induction power supply is designed to match multi-turn coils (400-2000 V) that are used for multi-turn hardening or tempering, tube heating, crystal growing, wire and strip heating and many other induction heating applications.

With built-in load tuning capacitors and multi-tap output isolation transformers, a variety of heating coils can be matched for full power operation over a range of load conditions. Allowing for standalone or ensemble operation, TFD power supplies cabinets are designed to accommodate a variety of fixtures, conveyors, and part handling machines. The system is designed to sweep from high frequency to low frequency, an inherently safer operation that greatly reduces the chance of failure by preventing large spikes of power upon initial start-up.

Digital-iQ

The TFD induction power supply is equipped with the intuitive, high speed Digital-iQ™ control platform. Specific to Radyne equipment and built for quick and simple usability, the Digital-iQ™ controls provide advanced communication, control, and programming features to achieve unbeatable accuracy. The Digital iQ™ controllers utilize technology that is 100% digital and ramps from 0-100% of rated power in under 500 microseconds. The Digital iQ™ controllers also offer advanced communication, control, and programming features in multiple frequency ranges for additional ease of use.

Each unit can be operated by direct manual controls on the unit, programmed via an internal digital controller, by a programmable logic controller, or from a remote control box. The companion Digital iQ™ controls for desktop allows operators to remotely connect, control, and monitor a TFD unit. Able to monitor and graph multiple data sources on the remote unit allows for precise monitoring of process parameters. Processing the Digital-iQ™ controller data is simple as graphs and tables are printable, and tabulated data is exportable as excel workbooks.

Multi-level password protection secures data and can easily be created using the digital interface.
