FC-101P45KT4E20H3 by Danfoss

The Danfoss FC-101P45KT4E20H3 HVAC drive from the VLT FC 101 HVAC Basic Drives series is engineered for precise climate control in industrial automation environments. This model delivers a robust 45 kW power rating at a standard 380 V input voltage and a continuous 90 A current rating, making it ideal for medium to large HVAC systems. Utilizing its primary V/f control (Volts per Frequency) method, the drive adjusts motor speed across an output frequency range of 0–100 Hz to optimize performance and minimize energy consumption.

Incorporating a durable IP20 ingress protection enclosure and fan cooling, the FC-101P45KT4E20H3 ensures stability and reliability within an operating temperature range of –10 °C to +50 °C. The drive achieves an efficiency of 95%, reducing operational costs and heat generation. Its overload capacity of 150% for 1 minute supports transient loads, while the built-in LED display with keypad interface provides intuitive local monitoring and configuration.

For seamless integration, the drive supports Modbus RTU and BACnet communication protocols, facilitating centralized control and data exchange in modern building management systems. Wall or panel mounting options simplify installation in tight enclosures. Advanced safety features such as motor overload protection and short circuit protection safeguard equipment and personnel. By combining energy-efficient motor management, flexible installation, and comprehensive safety functions, the FC-101P45KT4E20H3 enhances system longevity and reduces maintenance downtime in demanding industrial HVAC applications.
