Product Description:
The FC-202P18KT6131L1789 is a variable-frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. It receives three-phase utility power and produces a modulated output that allows centrifugal pumps and fans to track real-time demand in water and wastewater installations. By integrating voltage, current, and frequency control in one enclosure, the product functions as the primary speed regulator within an automated process loop. This arrangement allows a connected control system to adjust motor speed in response to changing flow or pressure requirements.
The power section supports a continuous apparent load of 26.9 kVA at 575 V, establishing the transformer and switchgear capacity required upstream. Steady-state input demand is limited to 24 A, while the inverter can supply 27 A of motor current without exceeding its thermal limits. Short bursts can reach 30 A to cover acceleration peaks, and a 50 A coordination fuse provides fault protection. Conversion efficiency is 0.98, so approximately 2% of incoming energy is converted to heat during operation. The mechanical power rating of 18.5 kW supports midrange pump duties commonly found in municipal water facilities. At full load, the resulting heat output must be considered when selecting cabinet ventilation and maintaining adequate clearance around the drive.
The output frequency can be adjusted up to 590 Hz for applications that require high-speed motor operation. Full performance is maintained at ambient temperatures as high as 50 °C when the installation altitude does not exceed 1000 m. The design tolerates a line-voltage imbalance of 3.0% and operates at relative humidity levels up to 95% without condensation. Motor leads may extend up to 150 m when shielded or 300 m when unshielded, providing flexibility for installations with remote pump rooms. Total internal losses are 370 W at full load, so cabinet airflow must remove this heat to keep the power semiconductors within their operating temperature limits.
