Product Description:

The 131F9757 is a variable-frequency drive from Danfoss's VLT FC 102 HVAC Drives series for fan, pump, and compressor control in building automation. Installed between the mains supply and an induction motor, it adjusts output frequency to match changing load demand. That operating method can reduce energy use in ventilation and water systems while supporting steady process control.

This unit accepts 380-480 VAC on a three-phase line, giving it the electrical input commonly used in commercial HVAC equipment. It includes a Mains Disconnect, so the drive can be isolated quickly during service. The enclosure carries an IP20 rating for touch-safe cabinet installation, and standard cable entries support orderly wiring in control panels.

A Graphical Local Control Panel provides parameter access through a multilingual interface, which helps technicians review settings without external tools. The drive also includes an RFI filter to limit conducted electrical noise, and it is intended for normal cabinet mounting with convection-based cooling. It ships with the latest release standard software, and its uncoated circuit boards suit controlled indoor environments rather than harsh or washdown areas.

Wake Industrial stocks this drive for immediate dispatch when replacement timing is important. Same-day shipping can be arranged when schedules are tight and order processing is completed before the cutoff. Quotations remain active for 30 days, which helps maintenance teams compare budgets and approvals before committing to a purchase. That availability is useful when an HVAC drive failure interrupts airflow, pumping, or compressor operation in an occupied facility during peak demand periods.
