Product description

The Danfoss 130B2444 sits as a sine-wave output filter in the three-phase power path between the frequency converter and the motor. Within the VLT-MCC-101 series, it operates according to the Differential-Mode low-pass principle. The subject of the filtering is the voltage between the motor phases and in particular the switching frequency component of the converter output. The assembly therefore belongs to the electrical output side of the drive system; its function must be distinguished from the infeed of the frequency converter. The assigned version covers a voltage range of 200 to 500 V AC. Input and output are each three-phase, and the frequency specification is 50/60 Hz. The rated current is specified as 10 A at a reference temperature of 40 °C. This temperature condition belongs to the current specification and must be read along with it when classifying the electrical load. The variant 130B2444 also includes a motor power assignment of 4 kW. Current value, voltage and power assignment describe the same filter version. The mechanical version is built as a wall-mounted unit with degree of protection IP20; for this Danfoss sine-wave filter, shipping from Germany to the United States and other international destinations is tied to the respective order. Within the MCC-101 family, this design differs from the larger floor-mounted variants. The housing measures 90 mm in width, 246 mm in height and 205 mm in depth, with a weight of 7.1 kg. The small module width and the greater installation depth determine the spatial arrangement of the individual filter assembly. Electrically, the assignment to the three-phase converter output remains decisive; mechanically, wall mounting, housing dimensions and degree of protection are the described version characteristics. Within this filter series, the order number 130B2444 designates the combination of the 10-A current stage and the 4-kW power assignment.
