195N0028 by Danfoss

The 195N0028 is a low-voltage AC drive produced by Danfoss within the VLT 2800 Low Voltage Drives series. Intended for process automation tasks, the unit varies motor frequency and voltage so that flow, pressure, or conveyor speed can be matched to real-time demand. By operating from a single-phase supply, it brings variable-speed control to small pumps or mixers in installations where three-phase power is unavailable. Its compact footprint also helps conserve control-panel space in smaller electrical enclosures, making it suitable for compact industrial equipment that still requires adjustable motor speed.

Electrically, the drive accepts 200-240 V AC on a single-phase circuit and can deliver up to 1.0 HP, which corresponds to a nominal 0.75 kW output rating. A protection level of IP20 helps prevent accidental contact with live parts after the unit is installed inside an enclosure. Torque remains linear across the adjustable speed range through internal PWM control, supporting stable centrifugal and positive-displacement loads. Because the unit is supplied without an application option and without coating, it is intended for clean electrical rooms where additional protective treatment is not required.

The slim book-style housing keeps the drive compact in a control cabinet, and a built-in display (SLCP) provides parameter entry and operating status feedback. The display also allows local access to settings and status messages at the drive. A hardware build described as standard with a brake includes an internal brake chopper so regenerated energy can be dissipated during rapid deceleration or vertical load control. Conducted emissions are limited by an integrated RFI network that meets EN 55011 Class A1, allowing the drive to operate near other electrical equipment with reduced interference. No fieldbus option is installed, so commands are handled through analog inputs or digital terminals.
