Product Description:

The FC-102P4K0T4Z55H1XGX1XXSXXXXAXBXCXXXXDX is an AC variable frequency drive produced by Danfoss for the VLT FC 102 HVAC Drives series. Designed for fan and pump applications, it converts fixed-frequency mains power into a variable-frequency output for regulating motor speed. This control allows building automation systems to stabilize duct or pipe pressure, adjust airflow or fluid flow according to demand, and reduce energy consumption in climate control equipment.

The drive accepts 380–480 VAC through its three input terminals, allowing direct connection to common industrial power distribution systems within that voltage range. It operates with three-phase power, which provides balanced current delivery to the connected equipment. Radio-frequency interference is attenuated by an integrated filter rated for RFI Class A1/B (C1), helping reduce conducted interference near building-management wiring and other sensitive control circuits. A factory-installed mains disconnect isolates incoming power from the inverter when electrical access is required. Local operation is provided through a graphical local control panel with a display and keypad for editing parameters, viewing operating trends, and acknowledging faults. These controls also provide direct access to drive status information without requiring a separate operator interface.

The drive is supplied with standard cable entries, allowing conductors to pass through compatible metric cable glands without additional entry adapters. Option slots A, B, C0, C1, and D are unoccupied, leaving the base control arrangement available for the stated fan and pump functions. The unit has no brake chopper, so regenerative energy must be managed by another suitable part of the drive system. The drive uses uncoated printed circuit boards, making installation in a clean, dry enclosure important where moisture or corrosive airborne contaminants may be present. A standard language pack provides multilingual text for menus, operating messages, and fault information. Status words and operating parameters remain available to higher-level controllers through the drive’s standard control structure. Adaptation B is disabled, so the corresponding parameter behavior remains unchanged from the base configuration.
