Product Description:

The 131B9530 is a variable frequency drive built by Danfoss and assigned to the VLT FC 202 AQUA Drives series. Within automated filtration, irrigation, and wastewater plants, it regulates the synchronous speed of induction motors so pumps and blowers deliver only the flow that the PLC demands. By replacing throttling valves with electronic speed control, the device reduces energy consumption and extends mechanical service intervals. Its variable-speed operation also reduces the stress caused by abrupt motor starts and stops in fluid-handling systems.

The drive is rated at 90 kW, giving it sufficient continuous output for large submersible or split-case pumps that move high volumes. Its mechanical output corresponds to 125 HP, a rating commonly used for older equipment in North American installations. It accepts line voltages from 380–480 VAC, allowing one configuration to operate on both 400 V European grids and 480 V North American mains. The drive requires three-phase power, which distributes the electrical load evenly and keeps motor torque pulsation low. A molded housing rated at IP66 / NEMA 4X prevents splashed chemicals, driven rain, and washdown water from reaching the control boards. This enclosure allows the converter to be installed close to the process without requiring a separate protective cabinet.

An integrated RFI filter attenuates conducted noise, helping the installation meet emission limits when motor cables run parallel to instrumentation wiring. Local setup and diagnostics are performed through the Graphical Local Control Panel, which presents parameter groups, trend readouts, and alarm histories on a backlit display with soft keys. The interface provides direct access to operating status and adjustment menus without requiring a separate computer for routine changes. Cable sealing is streamlined by standard cable entries molded into the die-cast base, eliminating the need for custom gland plates. The Standard Language Pack supplies multilingual text strings that make menu navigation accessible to users in different regions without requiring additional software uploads.
