Product Description:
The FC-102N315T4 is an AC variable frequency drive produced by Danfoss for the VLT FC 102 HVAC Drives series. It converts fixed-frequency mains power into a modulated output that allows building automation systems to regulate fan, pump, and compressor speeds according to real-time heating, ventilation, and air-conditioning demand. By varying motor frequency instead of relying on mechanical throttling, the unit can reduce unnecessary energy use across large commercial or industrial facilities. Its HVAC-focused controls support variable-speed operation in systems where airflow, pressure, or temperature requirements change throughout the day.
The drive accepts a mains voltage range of 380 to 480 VAC at 50/60 Hz, making it compatible with common industrial utility grids. When supplied from 380 to 440 V lines, the inverter draws 567 A continuously and delivers 588 A to the motor terminals. On 441 to 480 V sources, it draws 516 A and delivers 535 A, reflecting the lower current associated with higher supply voltage. The nominal mechanical output is 450 HP, and the synthesized output frequency can be adjusted from 0 to 590 Hz to support various four-pole and high-speed motors. Short overload events are supported at 110% for 1 minute every 10 minutes, while the peak output current reaches 647 A or 588 A for 60 seconds, depending on the line voltage.
The drive provides 315 kW of continuous output and dissipates 6,674 W of heat, which must be considered when providing ventilation for the electrical room. Continuous operation is permitted at ambient temperatures ranging from 0 °C minimum to 40 °C. Above 40 °C, the unit can continue operating with output derating until the enclosure temperature reaches 55 °C. The unit uses a three-phase power input to supply its inverter stage. Its adjustable output is suitable for large HVAC motors that must respond to changing airflow or fluid-demand commands from a building control system. The available operating range also permits the drive to maintain controlled motor performance while accommodating variations in load and supply conditions.
