195N1100 by Danfoss

The 195N1100 is an adjustable-speed AC drive produced by Danfoss and placed within the VLT 2800 Low Voltage Drives series. The unit modulates the frequency and voltage supplied to induction motors so machinery can match torque and speed demands in process automation cells. Designed for cabinet mounting, this book-format controller provides a compact way to add variable-speed motor control on 380 to 480 V production lines. This type of control helps match motor output to changing loads in fans, pumps, and conveyor systems.

It is rated for 10 HP, equivalent to 7.5 kW, so it can start and regulate pumps or conveyors without derating under normal conditions. The power terminals accept 380-480 V ± 10% at 50/60 Hz, allowing connection to common three-phase industrial supplies. The unit includes an internal brake chopper to dissipate regenerated energy during deceleration, which helps control overvoltage during rapid stopping. Its built-in RFI filter meets EN 55011 Class A1, reducing conducted emissions on the line supply, and the housing carries an IP20 rating that protects against finger contact while relying on the cabinet for additional sealing. The printed circuit boards are uncoated, and no application option or fieldbus plug-in is installed, so the base configuration remains focused on standard speed control.

The book-style footprint lets several drives sit close together on DIN rails while maintaining airflow between units. Parameters are set through the built-in display (SLCP), which provides status readouts and local access to operating values without external tools. The local interface also allows quick review of drive status during routine setup and operation. Because the unit uses a three-phase supply, it matches the motor circuits commonly found in factory equipment. Danfoss designates it for process duty, so it is suitable for flow, pressure, and mixing applications that benefit from adjustable motor speed. With no extra option cards installed, the base unit handles core drive functions in a simple cabinet layout.
