Product Description:
The 131U9349 is an AC variable frequency drive manufactured by Danfoss within the VLT FC 102 HVAC Drives series. Intended for building automation, the drive converts fixed-frequency mains power into a variable output that allows controllers to modulate the speed of supply fans, return fans, and chilled-water pumps. By matching motor speed to real-time load demands, it supports energy-efficient air handling and temperature regulation across commercial and industrial facilities.
The unit delivers a continuous electrical output of 18.5 kW, equivalent to 25 HP, so it can power medium-sized HVAC motors. It accepts a supply range of 380–480 VAC with three-phase power, enabling direct connection to standard switchboards. The housing has a protection rating of IP55 / Type 12, which shields the internal electronics from dust and water jets when the drive is wall-mounted outside a cabinet. For electromagnetic compatibility, the integrated filter meets RFI Class A1/B (C1), allowing installation in residential or light-industrial areas without additional suppression hardware. The configuration does not include a brake chopper, so regenerative braking energy cannot be dissipated through an internal braking resistor. The printed circuit boards do not have a conformal coating.
Local interaction is provided through the Numerical Local Control Panel, a keypad that displays setpoints and operating data while allowing parameter changes without external tools. The panel provides direct access to drive status, motor information, alarms, and adjustable operating values. The application software belongs to the VLT HVAC Drive group and provides functions such as proportional pressure control, automatic energy optimization, and fire-mode operation. Language selection is handled by the Standard Language Pack, allowing menus and alarms to appear in several widely used languages.
