Product Description:

The FC-202P15KT6131G2337 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. Designed for pump and fan duties in water and wastewater facilities, the unit converts fixed-frequency mains power into a modulated output that lets controllers match motor speed to real-time flow demand. An embedded control platform manages torque regulation, monitors feedback, and communicates status through the standard drive keypad or optional fieldbus interfaces, allowing acceleration profiles to be adjusted without additional hardware.

Electrical capability is anchored by a continuous power rating of 15 kW, equivalent to 20 HP, delivered to the motor terminals from a three-phase power supply. At nominal load, the semiconductor stage reaches an efficiency of 0.98, and the drive therefore meets the IE2 energy efficiency class for system-level savings. The inverter can modulate the carrier frequency up to 32 kHz, allowing low audible noise during operation with standard induction motors. Two differential analog inputs with 0.5 % full-scale accuracy are digitized at 10-bit resolution, enabling proportional feedback from pressure or flow transmitters. One analog output supports loads down to 500 Ω, while digital outputs source up to 40 mA for relay coils or opto-isolators.

Ambient air may reach 50 °C without derating, and continuous operation is possible at altitudes up to 1000 m. Above this altitude, the thermal model permits operation at up to 3000 m with current reduction. The unit tolerates noncondensing relative humidity of up to 95 %, while conformal-coated boards resist moisture in pumping stations. Motor leads may extend 150 m when shielded or 300 m when unshielded, accommodating deep-well or distributed pump layouts. The unit accepts a maximum pre-fuse rating of 40 A and protects downstream windings through adjustable overcurrent, ground-fault, and phase-loss monitoring.
