Product Description:
The FC-202N200T4134F4178 is an AC variable frequency drive produced by Danfoss as part of the VLT FC 202 AQUA Drives series. It belongs to the VLT AQUA Drive product group and carries the 202 series identifier used for dedicated water and wastewater controllers. The unit converts fixed mains power into variable-voltage, variable-frequency output so induction motors in pumps, blowers, or aerators can run at the speed required by process demand, saving energy and extending mechanical service life in automated fluid-handling systems.
The drive has a rated motor output of 200 kW, while an input range of 380–480 VAC allows direct connection to common industrial power systems. It operates on three-phase power, and its efficiency meets the IE2 classification to limit conversion losses. The power module can switch at frequencies up to 32 kHz, allowing acoustic noise and motor heating to be balanced for the application. Four digital inputs, expandable to six, and one configurable analog output allow the drive to accept level, flow, or pressure references and transmit feedback for PLC monitoring. The built-in thermal relay trips at 170 A during a 40% duty cycle to protect the inverter from excessive current. Dynamic deceleration requires an external brake resistor with a minimum resistance of 2.0 Ω. Shielded motor leads may extend up to 150 m, while unshielded leads may extend up to 300 m without exceeding the stated electromagnetic compatibility limits.
For regenerative applications, the brake channel handles up to 78 kW at a 40% duty cycle and dissipates excess energy through an appropriately sized external resistor. Continuous service is permitted at ambient temperatures up to 50 °C, with full-load operation supported from 0 °C and reduced-load startup possible down to -10 °C. Installation at elevations up to 1000 m requires no reduction in current or carrier frequency. The drive tolerates up to 95% noncondensing humidity, allowing operation in damp pump rooms when suitable installation practices are followed. Its control electronics remain stable during line-supply fluctuations, and the programmable inputs and outputs keep process signals local to reduce cabinet wiring.
