FC-102P18K

The Danfoss FC-102P18K drive is a high-performance member of the VLT FC 102 HVAC Drives series, designed to deliver reliable and efficient motor control for heating, ventilation, and air conditioning systems. This model offers a power rating of 18 kW coupled with an output amp rating of 37.5 Amps, enabling smooth load management in both constant and variable torque applications. Engineered by manufacturer Danfoss, the FC-102P18K offers resilient construction and advanced control algorithms to optimize energy use and reduce operational costs. Built to stringent industrial standards, the drive’s feature set balances high overload capacity with precise speed regulation for demanding HVAC environments.

The FC-102P18K’s technical specifications include the product code FC-102P18K and the Danfoss alternative part number 131B4249 for straightforward procurement and cross-referencing. The unit’s overall footprint is defined by its dimensions of 480 mm (height) × 242 mm (width) × 260 mm (depth), allowing flexible installation in standard enclosure racks or wall-mounted panels. Its rugged end-product enclosure carries an IP55 protection rating, shielding internal electronics from dust ingress and low-pressure water jets. Core control features support both V/Hz and VFC modes, while integrated DC-link choke and brake transistor options deliver enhanced motor braking performance. The drive’s nominal supply voltage compatibility and UL/CE listings ensure compliance with global safety and performance directives.

In operation, the FC-102P18K leverages its built-in Essential Services Mode to maintain critical system uptime during voltage disturbances, isolating protective functions to safeguard connected loads. This feature set reduces the risk of shutdowns caused by transient spikes or sags, ensuring continuous HVAC operation in commercial and industrial facilities. The drive also incorporates automatic restart and intelligent ramp profiles, which minimize mechanical stress and extend motor life under variable load profiles. Thermal management is achieved through an efficient heatsink design and temperature monitoring circuitry, preserving performance in ambient conditions up to the IP55 design limits. Users benefit from real-time diagnostics and status feedback via the integrated keypad display or optional communication modules.

System integration is streamlined through standard communication interfaces, including Modbus RTU and Bacnet MSTP, enabling seamless connectivity with building management systems and supervisory control platforms. Programming and commissioning are expedited with the user-friendly LCP keypad, supporting parameter cloning and firmware updates in the field. The FC-102P18K is ideal for HVAC applications such as air-handling units, chilled water pumps, exhaust fans, and variable-air-volume systems where precise airflow and pressure control are essential. Its combination of robust protection, advanced control features, and compatibility with Danfoss service tools makes it a versatile solution for industrial automation and commercial building climate control.
