Product Description:

The FC-102P4K0T4Z55H1XGXXOXSXXXXAXBXCXXXXDX is an AC drive produced by Danfoss within the VLT FC 102 HVAC Drives series. It converts fixed-frequency mains power into a variable-frequency output that allows building-management controllers to regulate the speed of fans, pumps, and compressors. This control supports energy-efficient airflow and chilled-water distribution in industrial and commercial HVAC installations. Integrated PID control allows the drive to respond directly to pressure, temperature, or flow signals. Serial communication also enables the unit to exchange operating commands and status data with a building-management system. These functions allow the drive to operate as a standalone actuator and reduce reliance on mechanical throttling devices.

The power section accepts a supply of 380 to 480 VAC, allowing direct connection to common low-voltage distribution panels without a transformer. Operation with three-phase power balances the electrical load across the phases and helps minimize motor torque ripple. The factory-installed filter is rated as RFI Class A1/B (C1) to limit conducted electromagnetic emissions. This filter supports installation in locations where electrical noise must be controlled to protect nearby equipment. Local setup and diagnostics are handled through the detachable graphical local control panel, which displays parameters, operating trends, and alarm codes on a backlit screen. The removable panel also provides direct access to drive settings without requiring a separate computer. The control boards use uncoated printed circuit boards, making the unit suitable for clean, controlled locations where conformal coating is unnecessary. Adequate enclosure protection should be provided when the surrounding air contains moisture, conductive dust, or corrosive contaminants.

The drive includes no brake chopper, so it cannot route regenerative energy to a braking resistor through an integrated switching circuit. During deceleration, excess energy must be absorbed by the connected load or managed through suitable external equipment when rapid stopping is required. Text strings and help menus are provided through the Standard Language Pack, giving users access to the drive’s standard interface languages. The electronics carry Series Identifier 102, which corresponds to the FC 102 product platform and its supported option architecture. The drive includes current standard software functions for control, monitoring, alarms, and communication with compatible adapters. Its enclosure and integrated controls support direct use in HVAC systems that require variable-speed operation across changing airflow, pressure, or water-flow demands.
