Product Description:
The FC-102P37KT4E20H1TXCX is an AC variable frequency drive manufactured by Danfoss for the VLT FC 102 HVAC Drives series. It regulates the speed of induction motors used in air-handling units, pumps, and chillers. This control allows building automation systems to adjust airflow or fluid volume according to real-time demand rather than operating connected equipment continuously at full speed. The drive can also provide controlled acceleration and deceleration, reducing mechanical stress on motors, belts, valves, and other connected components.
This unit delivers a continuous output of 37 kW to the motor terminals during normal operation. For installations that use imperial ratings, this output corresponds to 50 hp. The input section accepts a line voltage of 380–480 VAC and operates with three-phase power, allowing connection to common industrial electrical systems without a transformer. Its open-chassis enclosure has an IP20 chassis rating, so the drive is intended for installation inside a control cabinet that limits dust exposure and accidental contact. An integrated electromagnetic filter meets RFI Class A1/B (C1) requirements, helping reduce radio-frequency interference that could affect nearby instrumentation and communication circuits. The unit does not include a mains disconnect, so power isolation must be provided elsewhere in the electrical installation.
The built-in Safe Stop function rapidly disables the motor output when the connected safety circuit opens. Long-term reliability in humid or lightly contaminated electrical rooms is supported by a conformally coated PCB, which protects circuit traces from moisture and airborne particles. The drive has no local control panel, so parameter entry and diagnostic access require a remote network interface or an optional pluggable keypad. Cabinet mounting keeps the open chassis protected while allowing ventilation around the heat-producing components. Remote access also allows the building control system to monitor operating status, issue speed commands, and retrieve diagnostic information without direct interaction at the drive.
