195N1099 by Danfoss

The 195N1099 is an AC motor controller produced by Danfoss and placed in the VLT 2800 Low Voltage Drives series. It is intended to modulate induction motor speed in process-oriented automation lines. The unit uses standard hardware and is delivered without an additional application option or a fieldbus option, so its core feature set can be integrated directly into control cabinets where network interfaces are handled by other devices. This arrangement keeps the drive focused on basic speed control in enclosed industrial installations.

This drive accepts a mains input of 380-480 V AC ±10% 50/60 Hz, allowing connection to common plant supplies without an external transformer. Its continuous power rating of 7.5 kW corresponds to a mechanical output of 10 HP, giving sufficient capacity for medium-sized pumps, fans, or conveyors. A protection rating of IP20 means live parts are finger-safe once the unit is installed in an enclosure, but the cabinet must provide overall dust and moisture protection. The built-in RFI suppression meets EN 55011 Class A1, so conducted emissions remain within industrial limits and additional line filters are unnecessary in most installations. Because the unit is delivered without coating, its printed circuit boards remain uncoated; this supports heat dissipation but requires placement in a clean, temperature-controlled space.

The slim Bookstyle housing lets multiple VLT 2800 units mount side by side to minimize cabinet width, and a built-in display (SLCP) offers local parameter entry and status viewing without an external keypad. The inverter is designed for three-phase operation, giving balanced current draw across supply conductors during acceleration, steady load, and regenerative braking. Its assigned application is Process, which indicates defaults aimed at constant-torque performance and stable speed regulation as operating demands change. Side-by-side mounting can also help conserve panel space when several drives are installed in the same enclosure.
