Product Description:
The 131L3112 is a variable frequency drive produced by Danfoss and placed in the VLT FC 102 HVAC Drives series. It belongs to the VLT HVAC Drive product group and is used in ventilation, pumping, and chiller circuits where adjustable motor speed can improve energy efficiency and stabilize process response. By converting fixed utility frequency into a controlled output, the drive lets building automation systems adjust fan or pump duty in response to temperature or pressure signals. This operating method supports smoother control than fixed-speed motor operation in many building-service applications.
It accepts an input supply of 380–480 VAC and is built for three-phase power networks, allowing direct connection to common industrial distribution panels. The enclosure has an IP20 / Chassis rating, so the unit is intended for installation inside a protected cabinet. An integrated RFI filter helps limit conducted emissions, while the A-slot contains the LonWorks MCA 108 interface for connection to a LonWorks-based building management system. A graphical local control panel provides access to operating parameters from the drive itself, and standard cabinet mounting keeps the heat sink aligned with normal airflow paths. The drive also uses a standard language pack and does not include a dedicated line disconnect option.
For control continuity during power interruptions, the D-slot is fitted with the MCB-107 24 V DC backup board, which keeps logic and network communication active until incoming power returns. Cable routing is simplified by standard cable entries, while the B option slot remains empty and no mechanical adaptation is fitted to the enclosure. The brake chopper function is not included, so regenerative energy must be dissipated in the motor or by upstream devices. Printed circuit boards are not conformally coated, all C-category option positions are vacant, and the line option bay is also unused. The drive is supplied with the latest standard software release, and inventory systems identify it with series code 102.
