Product Description:

The 131B0953 is an all-around frequency converter designed and engineered mainly by the engineering company Danfoss for sophisticated servo applications and industrial systems. Featuring a simple enclosure, this electrical module has a protection grade of IP 20 and is suitable for general motor control and monitoring. Unlike other servo drives, Danfoss drives such as the 131B0953 are typically easier to install and maintain. It can operate even without an encoder and can facilitate motion control on board. To function as intended, this servo unit must be connected to an appropriate power supply. Depending on the application, this electrical device can operate at either 50 or 60 hertz.

At nameplate conditions, the 131B0953 can achieve a power rating of 2 HP, or approximately 1.5 kilowatts. To maximize the potential of this compact drive, the supply must have a terminal voltage of 380 to 480 VAC. Like other Danfoss modules, this product employs a robust set of filters for compensating harmonics. As part of the FC-301 series, this product has an alternate model code of FC-301P1K5T4E20H2XGXXXXSXXXXAXBXCXXXXDX. Considering its enclosure type, this module can prevent the intrusion of small objects and accidental finger touch. Aside from accidental finger touch and harmonic compensation, this compact module also incorporates mechanical-vibration monitoring, allowing it to detect vibration trends during acceleration or transient periods.

When operated at a terminal voltage supply of 380 to 480 VAC, the 131B0953 can draw a maximum input current of 3.7 A continuously. For a brief period of time, the input current can achieve a peak value of 5.9 A. To accommodate these current ratings safely, the minimum cable cross section must at least be 4 square millimeters.
