Product Description:
The 131B7009 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 102 HVAC Drives series. It regulates the speed of three-phase induction motors used in air handlers, pumps, and cooling towers so building automation systems can match airflow or water flow to real-time thermal demand. By adjusting motor frequency and torque electronically, the unit reduces energy consumption and helps maintain stable indoor conditions without relying on mechanical throttling. This electronic control also allows connected equipment to respond smoothly as heating and cooling requirements change throughout the day.
The drive delivers a shaft output of 50 hp, equivalent to a continuous electrical output of 37 kW. The input section accepts 380–480 VAC from a three-phase power network, allowing direct connection to common industrial mains without transformers. An enclosure protection level of IP55 / Type 12 keeps dust and water jets away from internal components, so the drive can be mounted in mechanical rooms with limited shielding. Thermal management is handled by integrated heat sinks and forced-air paths sized for the drive’s power class. Vector-based control algorithms regulate the motor output to provide stable operation across changing speed and load conditions.
Electromagnetic compliance is supported by the built-in RFI filter, which attenuates conducted noise on both line and load cables so the installation can meet typical EMC limits for commercial buildings. Local setup is performed through the detachable graphical local control panel, which provides parameter access, trend readouts, and real-time fault logging without external tools. The panel uses the standard language pack, making its menus and operating messages easy to navigate across supported regions. The drive has no brake chopper, so applications requiring rapid dynamic deceleration must use suitable external braking equipment or permit the motor to coast. This arrangement is appropriate for many HVAC loads, where pumps and fans typically slow gradually after the output frequency is reduced.
