JUMO IPC power converter for up to 200A

The new version of these instruments is now able to drive low-voltage heater elements (such as SIC, molybdenum disilicide or infra-red radiators) up to a total power of about 42kW. This power level provides the capability of covering a wide spectrum of the heater elements on the market, for various applications.

The user enjoys the following advantages from the application of this new generation of power converters:

• the elimination of the reactive power component (and the reactive-power compensation network) leads to a considerable reduction in operating costs;
• the “soft” drive method guarantees a long service life for the expensive heater elements;
• the low-voltage heater elements can be operated directly off the electrical supply network, without requiring a matching transformer;
• the RC control function provides continuous monitoring of the resistance, as a protection against overheating of the heater elements in the upper temperature range;
• the voltage reserve provides automatic compensation for aging of SiC heater elements;
• since no transformer with switchable voltage taps is required, there is a significant saving of volume, weight and cost;
• the primary current consumption reduces wiring costs;
• amplitude control ensures compliance with present and future EU standards for harmonics and flicker.
