Product Description:

The 131F1135 is a modern variable-frequency drive manufactured by Danfoss and supplied within the VLT FC 202 AQUA Drives series. It is intended for water and wastewater automation, where it governs centrifugal pumps or blowers by matching motor speed to process demand. That operating approach helps reduce electrical consumption, pipe hammer, and bearing wear in continuous-duty municipal and industrial service.

The inverter connects to a three-phase supply at 380-480 VAC and should be protected by a 125 A pre-fuse when the mains option includes a disconnect with fuses. On that supply, it delivers a continuous output of 80 A and permits 88 A intermittently during pump starts. Those current ratings correspond to 45 kW of motor power while the design handles an apparent load of 62.4 kVA for standard pumping and blower duty cycles.

The mechanical format uses the C1 frame, and the enclosure carries an IP55 Type 12 backplate rating for protection in demanding indoor service. During operation, the unit dissipates 843 W of heat, so panel design must allow adequate thermal removal around the drive. Electromagnetic compliance is supported by the built-in RFI Filter, and a graphical Local Control Panel provides clear local commissioning access for operators during setup, routine parameter checks, and status review activities.
