Product Description:

The 131F0719 is a variable frequency drive manufactured by Danfoss within the VLT FC 102 HVAC Drives series. The unit modulates the speed of three-phase induction motors so building automation systems can match fan or pump output to actual heating, cooling, or ventilation demand. By adjusting motor frequency rather than relying on dampers or valves, it helps reduce energy use and mechanical stress in air-handling units, chillers, and similar process equipment.

This drive is supplied with standard cable entries, so line and load conductors pass through metric knockouts that fit common gland plates without extra adapters. Its input section accepts a voltage range of 200–240 VAC, allowing direct connection to low-voltage distribution networks found in commercial facilities. The drive requires three-phase power, which balances current draw across the supply phases and supports steady motor operation. An enclosure rating of IP21 / Type 1 protects the electronics against vertically dripping water and incidental contact when the unit is installed in a conditioned indoor space. Local setup and status review are handled through the front-mounted graphical local control panel, which presents parameter menus, operating data, and fault logs. The unit is intended for dry-room mounting, and the product line includes B, C, D, and E mechanical frames for different power ranges and installation requirements.

An integrated RFI filter attenuates conducted emissions, helping the drive meet typical electromagnetic compatibility limits without external suppression hardware. The control board uses an uncoated PCB, which is suitable for clean indoor environments but should not be exposed to high humidity, corrosive vapors, or conductive contaminants. Because the drive has no brake chopper, the motor and connected load must coast to a stop or use suitable external braking equipment when faster deceleration is required.
