Product Description:
The 132N8591 is a variable-frequency drive manufactured by Danfoss within the VLT FC 202 AQUA Drives series. It belongs to the VLT AQUA Drive product group and is designed to regulate induction motor speed in water and wastewater pumping stations, clarifiers, and aeration blowers. By adjusting output frequency, the unit helps match pump and fan flow to process demand while reducing energy use in fluid-handling automation systems. It is suited to applications where pumps and fans must respond smoothly to changing demand across a process line.
The drive is rated at 125 HP, or 90 kW, which allows it to supply full torque to large centrifugal pumps without external step-up gearboxes. Its input range of 380–480 VAC is compatible with regional utility systems, and the internal rectifier converts that supply into a DC link for IGBT modulation. The inverter is built for three-phase power output, so it is not intended for single-phase loads. A factory-installed mains disconnect with fuse provides local isolation and protects upstream wiring during service. The design does not include a brake chopper, and the printed circuit board is uncoated, so environmental protection depends on the enclosure. Standard cable entries on Adaptation A simplify conduit routing, while Adaptation B remains in the stock mechanical layout.
The backplate has an IP66 / NEMA 4X backplate rating, which helps seal the electronics against hose-directed water and corrosive mist often found near chlorination or filtration equipment. Operators interact through a graphical local control panel that provides on-site access to setup menus and real-time pump data. Electromagnetic compatibility is supported by the built-in RFI filter, which reduces conducted noise on the motor leads. The controller is supplied with the latest standard software release, and it uses the baseline AQUA feature set without a dedicated software option. Menus are presented through the standard language pack for straightforward local operation.
