Product Description:
The FC-102P1K1T4E20H1 131F3917 is an AC variable-frequency drive produced by Danfoss for the VLT FC 102 HVAC Drives series. In air-handling units, chillers, and booster pump sets, the drive adjusts induction motor speed so airflow or fluid volume matches real-time demand, reducing energy consumption and limiting acoustic output. Its control system supports common building automation signals, allowing variable-torque loads to connect to centralized supervisory systems without external signal converters. Motor speed can respond to changing pressure, temperature, or flow requirements rather than remaining fixed during periods of reduced demand.
The drive accepts a mains supply between 380–480 VAC, making it compatible with common low-voltage distribution systems. Its power terminals support three-phase power, which is suitable for standard commercial and industrial motor circuits. An integrated mains disconnect allows the inverter to be isolated without requiring a separate disconnect switch in the same panel. Conducted emissions are limited by a built-in filter rated for RFI Class A1/B (C1), reducing the need for additional filtering in compatible commercial installations. The IP20 chassis housing helps prevent accidental finger contact with live components when the drive is installed inside a suitable electrical cabinet. Cabinet placement must still provide the required clearance for ventilation, wiring, and access to the power terminals.
The drive belongs to the VLT HVAC Drive product group and carries the internal code 102. Its platform supports compatible parameter structures and option cards used within the same drive group. Mechanical integration accommodates A, B, and C frames for standard cabinet mounting, allowing the appropriate heat sink footprint and mounting pattern to be selected for the drive size. The control terminals are arranged for direct wiring to pressure transducers, temperature sensors, and building-management networks. These connections support automatic speed adjustment from process feedback while keeping sensor and communication wiring organized within the enclosure. The drive can regulate fans and pumps according to changing system demand, while centralized controls can monitor operating conditions and issue speed commands.
