Product Description:

The FC-102N110T4E20H4XGCXXXSXXX is an AC variable frequency drive manufactured by Danfoss for the VLT FC 102 HVAC Drives series. The unit converts fixed mains power to a variable output frequency so ventilation fans, pumps, and other HVAC loads can match real-time demand instead of running continuously at full speed. By integrating drive control into a standard cabinet, it supports energy-efficient air-handling and chilled-water loops commonly found in industrial automation and building management systems.

The drive is compatible with a 380–480 VAC supply, and the input must be balanced because the topology is designed for three-phase power. Within this range, the inverter can deliver a continuous mechanical output of 110 kW, equivalent to approximately 150 HP, making it suitable for large air handlers and cooling towers. The chassis has an IP20 chassis enclosure, allowing installation in clean switch rooms where protection against water jets is not required. Standard cabinet mounting on A, B, or C frames positions the heat sink for ducted airflow. The lack of an integrated mains disconnect means that external isolation hardware must be installed to disconnect incoming power when required.

Operator interaction is handled through a graphical local control panel that provides parameter entry and live operating readouts without additional programming tools. Field wiring passes through standard cable entries, allowing the use of common metric glands and conduit fittings. Circuit boards have a coated PCB finish that protects electrical traces from humidity and airborne contaminants commonly found in plenum spaces. The drive does not include a brake chopper, so deceleration energy must be dissipated through motor and load losses or managed by a suitable external braking solution when the application requires faster stopping. This arrangement is appropriate for fan and pump loads that typically slow over a controlled ramp rather than requiring rapid regenerative braking.
