195N0023 by Danfoss

The 195N0023 is a low-voltage AC drive produced by Danfoss for the VLT 2800 Low Voltage Drives series. The unit functions as a variable-frequency controller that regulates induction motors in process equipment, allowing speed adjustment and energy savings inside control cabinets and OEM machinery. By modulating output frequency, it supplies the torque profile needed for pumps, mixers, and other automation components that require steady speed control. Its compact role in cabinet-mounted systems makes it suitable for equipment where motor demand changes during normal operation.

The drive accepts a mains input of 200-240 V AC on a single-phase supply and converts it to a variable three-phase output for the motor. Its continuous power rating is 0.55 kW, which corresponds to 0.75 HP under nominal conditions, making it suitable for small centrifugal fans and light conveyors. Communication with supervisory controllers is available through DeviceNet, so setpoints and alarms can be exchanged over a fieldbus connection. A built-in SLCP alphanumeric display supports local parameter entry and status review at the drive. This arrangement allows basic control functions to remain accessible without requiring separate display hardware.

Mechanical layout follows a book-style format, so multiple drives can mount edgewise in shallow panels while conserving cabinet space. The enclosure carries an IP20 rating for protection against accidental finger contact, and conducted emissions are reduced by the integrated EN 55011 Class A1 RFI filter. The electronics are supplied without coating, so the unit is better suited to clean, dry cabinet environments than to high-humidity areas. The narrow mounting profile also helps maintain usable wiring space when several drives are installed side by side.
