Smart Power™

Induction Heating Innovation by Ultraflex

Ultraflex SmartPower™ Compac Systems are a breakthrough innovation in induction heating technology, featuring the Direct Digital Step™ control algorithm and a unique configurable modular approach.
Configurable and field upgradeable power supplies with output power from 50kW to 400kW.
Wide output frequency range – two ranges available from 6kHz to 60kHz and from 40kHz to 200kHz.
Zero downtime can be achieved if an additional module (N+1) is installed in the system.
The latest SiC transistor technology and proprietary digital control algorithms ensure optimal performance and maximum efficiency in a wide frequency range.
Ultra-flexible, wide range of load impedance matching by utilizing multiple transformer ratios and configurable capacitor banks.
Configurable to work with a single or multiple, independently controlled RF outputs from one cabinet.
Can operate with optional heat stations allowing the load coils to be placed remotely.
Durable and reliable design with built-in tuning, safety, and diagnostics features.
