Product Description:
The FC-202N315T4134G6941 is an AC variable-frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series. In water-handling applications, it regulates induction motor speed so that pumps and blowers deliver only the required flow or pressure. This control improves process stability and reduces unnecessary energy consumption within an automated plant. The drive can adjust motor operation in response to changing system demand, making it suitable for pump stations, water treatment systems, and related flow-control equipment.
This model supplies up to 315 kW of electrical output, equivalent to 425 hp on the motor shaft. It is powered by three-phase mains ranging from 380 to 480 VAC, and the internal power section has an IE2 efficiency classification to minimize conversion losses. The drive’s insulated-gate bipolar transistors can switch at carrier frequencies as high as 32 kHz, allowing low audible noise during motor operation. For rapid deceleration events, its braking chopper diverts up to 26 kW into an external resistor bank. The analog output stage supports loads down to 500 Ω for proportional valve or meter feedback. Digital outputs can sink up to 40 mA for relay coils or indicator lamps.
The braking circuit is protected by a thermostat-triggered 124 A relay and requires external resistors with a resistance of at least 1.2 Ω. The brake connection uses two conductors with a cross-sectional area of 35 mm². Motor leads may extend up to 150 m when shielded or up to 300 m when unshielded, providing flexibility for installations in large pump stations. The control electronics tolerate ambient temperatures up to 50 °C before derating is required. The drive can operate at elevations up to 1,000 m with full output or up to 3,000 m with a staged reduction in current. These installation limits support operation where motors, pumps, and control cabinets must be separated by substantial distances.
