Product Description:

The FC-202P1K5S2131G9673 is a variable frequency drive manufactured by Danfoss as part of the VLT FC 202 AQUA Drives series. It supports automated pumping and aeration tasks by adjusting motor speed according to process demand. This control can reduce water hammer, conserve energy, and maintain stable flow in water and wastewater systems. The drive belongs to the VLT AQUA Drive product group and carries the series code 202. Its application-oriented controls make it suitable for booster stations, treatment systems, membrane skids, and other installations that require regulated pump operation.

The drive has a rated motor output of 1.5 kW, which is equivalent to 2.0 HP. The input accepts 200–240 VAC single-phase power and draws a continuous current of 15 A. This input demand corresponds to 2.7 kVA when the drive operates at full load. The inverter provides a continuous output current of 7.5 A to the connected motor, supporting controlled torque during changes in pressure or flow. Its conversion efficiency is 0.98, resulting in approximately 30 W of internal power loss at the rated output. The semiconductor bridge and control electronics manage switching losses while regulating the motor current waveform to limit acoustic noise and motor heating.

Operation is permitted at altitudes up to 1000 m without derating and at ambient air temperatures up to 50 °C. The drive complies with the IE2 energy-efficiency classification for low-voltage drives. Upstream circuit protection may use a 30 A fuse, while protective grounding requires a conductor cross-section of at least 10 mm². Shielded motor cables may extend up to 150 m, while unshielded motor cables may extend up to 300 m. Motor cable insulation must be rated for 75 °C to withstand repetitive pulse-width modulation voltage peaks. These cable limits provide the required operating range for installations with either shielded wiring for electromagnetic compatibility or longer unshielded runs where permitted.
