A series of frequency converters for heating, ventilation and air conditioning systems, as well as for pumping equipment and general industrial applications, including heavy-duty starting.
Thanks to the compact design, this series of converters allows wall-to-wall installation without compromising performance. The separated cooling system prevents air from passing through the electronic components, which extends the service life of the frequency converter. The efficient cooling system allows operation at ambient temperatures up to 50 °C. The device has removable fans for easy maintenance.
RD11 reduces costs and commissioning time thanks to built-in elements such as an EMC filter, a brake interrupter unit, and a convenient control panel with a potentiometer. The frequency converter has a modular structure, and its functionality can be expanded with special optional boards.
