195N1123 by Danfoss

The 195N1123 variable frequency drive from Danfoss belongs to the VLT 2800 Low Voltage Drives series. In plant automation, this compact unit regulates the speed of three-phase induction motors so equipment can follow changing load demands with smoother acceleration and reduced mechanical shock. The 195N1123 installs in switchgear cabinets as a stand-alone controller or as part of a coordinated drive system, making it suitable for pumps, fans, conveyors, and other machinery that benefits from controlled motor speed. Its compact cabinet-oriented design also helps it fit applications where panel space is limited and a simple low-voltage drive platform is preferred.

Its continuous mechanical output is rated at 20 HP, which corresponds to an electrical power rating of 15.0 kW. The drive accepts a supply of 380-480 V ±10% 50/60 Hz and is intended for a three-phase grid, allowing it to operate on common industrial power systems with balanced input loading. The enclosure is rated IP20, so it provides finger-safe protection against contact with live internal parts but is still meant for installation inside a control cabinet. This arrangement suits enclosed panels where surrounding equipment and wiring are already protected from open access.

The mechanical layout uses the Bookstyle format, which helps maintain airflow when multiple drives are mounted side by side in a cabinet. Local setup is handled through the built-in display (SLCP), which shows parameter numbers, setpoints, and fault codes without requiring an external keypad for basic access. The configuration is standard, meaning the unit is supplied without coating, without an application option, and without a fieldbus board, while an integrated cable-length-dependent RFI filter supports category A1 or B compliance. The dedicated application setting is Process, which suits steady speed control duties in continuous manufacturing lines where predictable motor response and straightforward operator access are useful.
