Product Description:

The FC-102P15KT4E55H1XGXXXXSXXXXAXBXCXXXXDX variable frequency drive is manufactured by Danfoss for the VLT FC 102 HVAC Drives series. Within the VLT HVAC Drive product group, this model uses series code 102 and is installed in building automation panels to regulate the speed of centrifugal fans, pumps, and compressors. By converting fixed line power into a variable output frequency, the unit allows process controllers to match motor torque and speed to real-time thermal demand. This operation can lower energy use and reduce mechanical wear in equipment that does not need to operate continuously at full speed.

Its continuous mechanical output is 15 kW, which is the maximum load the inverter can handle continuously without derating. For applications that use imperial units, the corresponding output is 20 HP, placing the drive in the midrange for HVAC service. The power stage accepts line supplies from 380–480 VAC and requires three-phase power, allowing direct connection to common 400 V distribution systems. Control electronics and bus capacitors are housed in an enclosure rated IP55 / Type 12, which protects internal components against dust and water jets. A brake chopper is not fitted, so regenerated energy must be managed through the motor or suitable external equipment. The standard configuration maintains a consistent control architecture for integration with building management systems. Its variable-frequency output supports gradual acceleration and deceleration, which can reduce pressure surges in pumps and limit abrupt mechanical loading in fan systems.

Adaptation A provides standard cable entries with metric gland openings that align with typical HVAC enclosure plates. A front-mounted graphical local control panel provides local start and stop commands, parameter transfer, and trend functions. Conducted emission control is handled internally by an RFI Class A1/B (C1) filter, reducing the need for additional line-filtering components in compatible installations. The electronics use uncoated printed circuit boards, making the drive suitable for controlled indoor cabinets where tropical varnish is unnecessary. The local interface gives operators direct access to operating values and drive settings without requiring a separate display. Standard cable access also supports organized routing of line, motor, and control conductors while maintaining the enclosure’s protective performance when suitable glands are installed.
