Product Description:

The FC-202P15KT2131Z3638 is an AC variable frequency drive produced by Danfoss within the VLT FC 202 AQUA Drives series. The unit modulates supply voltage and frequency so centrifugal pumps, aerators, and filtration blowers can match demand in water-handling installations, lowering energy consumption and mechanical stress. As part of the AQUA platform, it is optimized for wet-process duty and offers dedicated pump functions alongside standard motor speed control.

It operates from an input range of 200–240 VAC and delivers a continuous electrical output of 15 kW, which corresponds to a mechanical output of 20 HP. At rated load, the converter draws 54.0 A and supplies the motor terminals with up to 59.4 A, allowing ample torque during starting or flow transients. Energy is dissipated through an external brake resistor when required. The minimum resistance is 8.7 Ω, the nominal resistance is 10.2 Ω, and the resistor can absorb 1.13 kW of heat. The drive has an estimated power loss of 602 W that must be removed through panel ventilation. The maximum shielded motor-lead length is 150 m, while the maximum unshielded length is 300 m, supporting connections to remotely located pumps without additional reactors.

The apparent power drawn from the mains reaches 21.4 kVA, and the overall conversion efficiency is 0.96, which limits energy losses when the inverter operates near its maximum ambient temperature of 50 °C. Supply conductors may be protected by a maximum pre-fuse of 80 A and terminated with disconnect lugs that accept conductors up to 35 mm². Continuous operation is intended with three-phase power, providing the balanced supply required by the converter. The unit supports line disconnection without loss of encoder feedback, and its cable clamp accommodates the stated conductor cross-section to help maintain an orderly cabinet layout.
