195N1049 by Danfoss

The 195N1049 AC drive is produced by Danfoss and belongs to the VLT 2800 Low Voltage Drives series. As a variable-speed controller for three-phase induction motors, it is used in process automation lines to adjust pump, fan, and conveyor speed according to load demand. By converting a fixed mains supply into an adjustable output frequency, the drive helps maintain torque while reducing energy use and mechanical wear. This supports general industrial duty where stable speed control is needed across changing process conditions. Its compact footprint allows side-by-side installation where cabinet space is limited.

It delivers a nominal mechanical output of 3.0 HP, while its electrical power rating is 2.2 kW. The input range of 380-480 V allows operation on common industrial supply networks, and the tolerated line frequency of 50/60 Hz means the same unit can be used in different regions without hardware changes. Internally, the converter requires a three-phase feed, which helps maintain balanced current draw and smooth motor operation. The standard hardware configuration leaves the control slot without additional option cards, and the drive ships without an integrated RFI filter. External suppression must be added where lower conducted interference is required.

The housing has an IP20 rating and uses a book-style format suited to dense cabinet layouts. A built-in display (SLCP) on the front panel provides local parameter access for the Process application family. Because there is no application option board or fieldbus option, control is handled through the standard terminal strip. The unit also lacks a protective coating, so it is best used in clean, noncorrosive environments. These limits should be considered when the drive is installed in cabinets exposed to moisture, conductive dust, or aggressive air contaminants.
