Product Description:

The FC-202P1K1T4134F6401 is an AC variable frequency drive produced by Danfoss as part of the VLT FC 202 AQUA Drives series. It is intended to regulate centrifugal pumps, blowers, and other water-handling motors by modulating the stator frequency rather than using mechanical throttling. By converting fixed-frequency three-phase mains into a variable output, it enables flow, pressure, and energy consumption to remain proportional to real-time demand in industrial automation systems that manage treatment basins, cooling towers, and irrigation loops.

The drive accepts a supply between 380 to 480 VAC and uses three-phase power, matching common industrial mains. Its power section delivers 1.1 kW of continuous output, equivalent to 1.5 HP, and the branch circuit is safeguarded with a 10 A pre-fuse. Motor conductors can be run in copper up to 4 mm², while the detachable disconnect terminal accepts cables as large as 6 mm². Control terminals provide an analog output range of 0/4–20 mA with 8-bit resolution. The output can drive loads with a minimum resistance of 500 Ω for proportional speed or process feedback. Four standard digital inputs are provided, and each input presents 4 kΩ of impedance. A single digital output is available for status signaling to external devices, such as relays, alarms, or supervisory controllers.

For frequency-based signaling, the terminal block supplies a pulse stream rated to 32 kHz with 12-bit resolution and supports a minimum load resistance of 1 kΩ. This output suits modern flow meters and PLC high-speed counters used for process monitoring and closed-loop control in water-treatment and pumping systems. Each digital input withstands 28 V DC. The transistor output can provide 40 mA to actuate indicator lamps without exceeding its rating.
