Product Description:
The FC-102P15KT4E55H1 is a variable frequency drive manufactured by Danfoss for the VLT FC 102 HVAC Drives series. In HVAC automation, the unit modulates the speed of centrifugal fans, pumps, and compressors to match airflow or water circulation to real-time demand. Variable-speed operation can reduce energy consumption when equipment does not need to run at full capacity. Controlled acceleration and deceleration also limit mechanical stress on motors, couplings, belts, and connected equipment.
This model supplies 20 HP of mechanical output and accepts a mains input range of 380–480 VAC, allowing connection to common industrial power systems without a transformer. It operates with three-phase power, which provides balanced current draw across the supply conductors. The inverter has a continuous electrical power rating of 15 kW for variable-speed ventilation and pumping applications. Its IP55 / Type 12 enclosure protects internal components against dust and water jets, allowing wall mounting in suitable mechanical rooms without a separate cabinet. The protected housing supports installation near indoor air-handling units, cooling towers, and hydronic distribution equipment where airborne contaminants or occasional water exposure may occur.
Electromagnetic compatibility is supported by an integral RFI Class A1/B (C1) filter that attenuates conducted electrical noise. When the drive is installed with the required grounding, shielding, and cable practices, the filter helps limit interference with nearby electrical and control equipment. HVAC control functions include automated belt monitoring, which can detect operating conditions associated with a broken or slipping fan belt. The built-in sleep mode can stop the motor when system demand falls below the configured threshold and restart operation when demand returns. The drive’s thermal path removes heat from the power electronics during continuous operation, while its control algorithms regulate motor speed in response to commands from a building management system.
