The Danfoss VLT FC 102 HVAC Drives series is a family of variable frequency drives developed for heating, ventilation, and air-conditioning applications, with built-in control functions tailored to pumps, fans, and compressors.
The series is designed to simplify commissioning and reduce external hardware requirements by integrating application-specific functionality, Smart Logic Controller capability, and multiple HVAC communication options for building-management connectivity. Available supply classes include 3 x 200-240 V, 3 x 380-480 V, 3 x 525-600 V, and 3 x 525-690 V versions, with power coverage extending from 1.1 kW to 1400 kW depending on the voltage range and configuration. The platform also incorporates integrated DC chokes and RFI filtering to reduce harmonic distortion and electromagnetic interference, while enclosure options up to IP66 and optional coated circuit boards support use in harsher operating environments. The FC 102 series is intended for HVAC installations that require energy-efficient variable-speed control, compact installation, safety functions such as Safe Torque Off and Safe Maximum Speed, and operation at ambient temperatures up to 50°C without derating.
