The Danfoss 131B7535 is a compact and efficient AC variable frequency drive (VFD) designed for reliable motor control in HVAC, building services and industrial ventilation applications. As part of the Danfoss VLT HVAC Drive FC-102 series, it is engineered for fans, pumps, compressors and heating, ventilation and air conditioning systems where energy efficiency and dependable performance are essential.
This drive provides dedicated HVAC functionality in a compact IP20 chassis format. The VLT HVAC Drive range is widely used in building automation systems because it helps optimise motor speed, reduce energy consumption and improve comfort control in ventilation, pumping and refrigeration applications.
With a rated output power of 4.0 kW / 5.0 HP, a three-phase 380–480 V AC supply and a Frame A2 chassis format, the 131B7535 is suitable for HVAC motors used in fans, pumps and air handling equipment. Its built-in RFI Class A1/B filter supports electromagnetic compatibility in suitable installations, while the IP20 chassis design allows straightforward installation inside electrical control panels.
Variable frequency drives such as the Danfoss VLT HVAC Drive FC-102 regulate motor speed by adjusting output voltage and frequency. In HVAC systems, this allows fans, pumps and compressors to operate only at the speed required, helping reduce energy use and improve overall system performance.
The 131B7535 is designed for compact control panel installations in building services, plant rooms and industrial HVAC systems. Its HVAC-focused functionality makes it suitable for applications where reliable motor control, efficient operation and smooth speed regulation are important.
