Product Description:
The FC-202P45KT4131B9048 is a variable frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. The device regulates induction-motor speed by modulating output frequency and voltage, allowing pumps, fans, and blowers in water and wastewater treatment plants to match changing hydraulic demand and reduce energy use. By adjusting motor operation to actual process needs, the drive supports pressure, flow, and level control across pumping applications. Its variable-speed output also reduces throttling losses and limits unnecessary motor operation during periods of low demand.
It accepts three-phase power from 380 – 480 VAC industrial grids. The inverter can deliver up to 45 kW of continuous output power to the connected motor, while pulse-width modulation operates at selectable carrier rates up to 32 kHz for acoustic performance and torque quality. Internal logic samples process data every 5 ms, allowing the controller to respond quickly to changes reported by process sensors. One analog output operates with 8-bit resolution and supports loads down to 500 Ω. The control terminal block includes digital inputs that withstand 28 V DC and two transistor outputs that can source 40 mA each. These connections allow external sensors and relays to exchange process signals with the drive. Drive parameters are grouped under the internal 202 identifier.
The drive maintains full current from 0 °C through 50 °C in ambient air. It functions without derating at altitudes up to 1000 m. Operation is permitted at up to 95% noncondensing relative humidity. Motor leads may run up to 150 m when shielded or up to 300 m when unshielded, providing flexibility in distributed pump stations. The available cable distances allow the drive to be installed away from motors located throughout a water-processing facility. The unit remains serviceable when cabinet ventilation keeps its internal components within the permitted thermal range.
