Product Description:

The 131L9866 frequency converter is one of Danfoss Automation's most efficient and popular products. It is part of the VLT FC 101 product series designed to be used for motor control in heating, ventilation, and air conditioning systems. It can also be used for the control of flow or pressure systems. The converter has a small IP20 housing design that makes it perfect for customers who have very little installation space and require the highest level of motion control for their systems. This product is an air-cooled device that requires ambient temperature levels less than 45 degrees Celsius. Applications that feature multiple units of this product can install them side by side with a minimum distance of 80 millimeters allowed above and below the product for easy heat dissipation. Although the 131L9866 comes with factory-determined configurations, customers are allowed to adapt the operation of the unit to specific applications using parameter instructions.

The 131L9866 produces significant radio interference during its operation, which is significantly reduced by the interference filter built into the unit from the factory. The temperature inside any motor connected to this product is monitored by the converter to prevent overheating. High temperatures are immediately detected and signaled to the operator through a specific error code. The 131L9866 is not delivered with a control panel; however customers can use its serial interface to connect it to a PC through which command instructions can be sent.

The 131L9866 converter is unique for its ability to deliver high performance while significantly saving energy by up to 50 percent in typical applications. The energy-saving capacity of this product is due to its ability to constantly adapt its operation to the requirements of the connected motor in real time.
