RD11 series refers to frequency converters for HVAC, as well as pump applications and general industrial applications, including heavy duty start. It can be executed with normal and high overload. The RD11 frequency converter is able to control asynchronous and synchronous motors. Having “booklet” design, this drive series allows for wall-to-wall mounting without compromising performance. Separation of the cooling system prevents air flow through the electronic components, which increases the service life of the frequency converter. The efficient cooling system allows operation at ambient temperatures up to 50 °C. The device has removable cooling fans for easy maintenance. RD11 UNI Drive reduces costs and commissioning time due to built-in elements such as EMC filter, brake interrupter unit, and user-friendly operator panel with potentiometer. The drive has a modular structure and its functionality can be extended by special additional boards. Automatic adaptation to the motor (with or without motor rotation) is available for this series, which makes commissioning quick and easy. The device has a built-in DC link choke (55 kW and more) that reduces harmonic distortion to less than 45% THiD and extends service life of the frequency converter.
