Pulsar IGBT Inverter Technology
The Pulsar IGBT system incorporates the latest in transistorised technology with digital microprocessor control for the efficient heating and melting of ferrous, non-ferrous and precious metals.
The Best Features
Diagnostics and real-time data are incorporated into a sophisticated software-driven touchscreen HMI with menu-driven features to provide the operator with the ultimate real-time and historical information.
The system includes its own integrated deionised closed-circuit water cooling circuit, a water conductivity meter, and a sensitive earth-leakage detection system.
The Reliable Choice
Intelligent fibre-optically fired IGBTs are digitally controlled to provide seamless operator control and system reliability.
Flexibility
Most Pulsar IGBT inverters connect directly to a standard distribution transformer and drive all makes and types of induction furnace bodies, from the smallest 75kW to the largest 750kW. The machine has many standard components across the range, which has significantly reduced the need for variants of the same component type.
Efficient and Simple
The Pulsar IGBT offers near-straight-line performance across the melt cycle, with an operating efficiency of around 98% while maintaining a near-unity power factor. Clearly laid-out instrumentation provides the operator with uncomplicated visual feedback showing the machine's operating conditions. Optional analogue metering can be offered, backlit with LEDs, in addition to the HMI display.
