Product Description:
The FC-202P45KT4131F6650 is an AC variable-frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series. It controls induction motors used in pumps, blowers, and aerators so that flow and pressure can be matched to demand in water and wastewater systems. By modulating motor voltage and frequency, it improves energy efficiency, reduces mechanical wear, and communicates with plant PLCs in municipal and industrial fluid-handling applications.
The drive connects to 380–480 VAC three-phase mains and can deliver up to 45 kW of mechanical power. Under continuous duty, it supplies 90 A to motors on 380–440 V networks and 80 A on 441–480 V networks, while drawing input currents of 82 A and 73 A, respectively. Apparent power reaches 62.4 kVA at 400 V and 63.7 kVA at 460 V, providing values for cable and transformer sizing. Its short-term overload capacity permits 99 A for 60 seconds on the lower voltage range and 88 A for 60 seconds on the higher range. A 125 A upstream fuse provides rectifier protection. The inverter carrier frequency can be set as high as 32 kHz to reduce audible motor noise. These electrical characteristics support three-phase pump and blower systems across the drive’s rated voltage range.
Control integration is supported by one 8-bit analog output and digital channels that the controller scans every 5 ms. The logic inputs tolerate up to 28 V DC, and each transistor output can source 40 mA for relays or status lamps. These signal levels allow connection to typical PLC cabinet components without external level shifters. The controller cycle time allows proportional-integral regulators to respond quickly to changes in system pressure and flow. Digital channels can exchange operating states, alarms, and control commands with connected automation equipment. The analog output can transmit a process value or operating reference to an external monitoring device. Plant control systems can use these interfaces to supervise pump operation and report process variables to SCADA platforms.
