Product Description:

The 131U1496 is an AC variable-frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series. This water-oriented drive platform regulates centrifugal pumps, blowers, and other fluid-handling motors used in industrial processing and municipal treatment plants. By converting fixed mains power into a controllable output waveform, the unit allows automated systems to match motor speed to real-time demand. Adjusting motor speed can reduce unnecessary energy use when pumping or airflow requirements fall below the maximum operating level. The drive also supports controlled acceleration and deceleration, reducing abrupt mechanical stress on connected pumping equipment.

This model delivers a continuous output of 3.0 kW, which corresponds to 4.0 HP. It connects to supply grids rated at 380 – 480 VAC and operates with three-phase power, so it is not intended for a single-phase supply. The power section uses an uncoated PCB, meaning the circuit boards lack conformal varnish and should be installed in a clean, dry enclosure. Adaptation A uses standard cable entries, simplifying gland-plate preparation and conductor routing during installation. Adaptation B is not included, which allows the drive to retain its basic physical configuration. The accessory positions identified as A, B, C0, C1, and D do not contain optional modules. The mains input section also omits an additional harmonics module, allowing external line-conditioning equipment to be selected separately when required by the installation.

User interaction is handled through a graphical local control panel, which provides access to operating data, parameter menus, and drive status information. Conducted electrical noise is attenuated by an integrated RFI filter, helping limit interference transferred through the mains connection. The drive has no brake chopper, so a braking resistor cannot be connected directly through an onboard chopper circuit. Applications with significant regenerative energy must therefore use an appropriate external arrangement or rely on a deceleration profile that prevents excessive DC-bus voltage. The product belongs to Series 202, placing it within the corresponding generation of the VLT AQUA drive platform. Its standard cable entries and unoccupied accessory positions leave room for installation-specific components elsewhere in the control enclosure.
