Product Description:

The 131G9993 is an AC drive from Danfoss in the VLT FC 202 AQUA Drives series. It is intended for variable-speed control of pumps and fans in water and wastewater systems, where adjusting motor frequency helps match flow or pressure to process demand. This approach reduces hydraulic shock and unnecessary energy use while supporting smoother starts and speed changes than fixed-speed motor operation. The drive fits applications such as circulation systems, pumping stations, and treatment equipment that need stable motor control across changing operating conditions. Its control profile is suited to variable-torque loads that do not need constant full-speed operation.

This unit provides 2.0 HP of motor output, which corresponds to a continuous rating of 1.5 kW. It is built for three-phase power, so it is suited to balanced industrial mains used in plant distribution systems. The enclosure has an IP21 / Type 1 rating, which is appropriate for installation in clean indoor electrical areas. A front-mounted graphical local control panel gives local access to operating data and parameter settings, and menu text follows the standard language pack used for this product line. The local interface also allows status review and routine adjustments without requiring a separate external setup tool.

Line isolation is provided by a mains disconnect with a fuse, which allows the incoming supply to be shut off at the unit. Wiring enters through standard cable entries, so the enclosure keeps its standard cable-routing arrangement without additional mechanical changes. The control boards have an uncoated PCB finish, so the drive should be installed away from condensing moisture and other contamination that can affect exposed electronics. The unit has no brake chopper, so braking energy must be handled by the surrounding system rather than by an internal chopper circuit. No additional mechanical adaptation is applied to the housing.
