195N0203 by Danfoss

The 195N0203 is a low-voltage AC drive produced by Danfoss within the VLT 2800 Low Voltage Drives series. This compact unit controls induction motors by adjusting supply frequency and voltage to match real-time demand in conveyors, fans, and other motion devices used across manufacturing lines. By integrating the power electronics and control logic in a single housing, the drive simplifies panel design, reduces the number of separate components needed in the enclosure, and supports energy-efficient motor speed regulation in industrial automation.

Electrically, the drive accepts a mains input of 200-240 V AC and is wired for single-phase supply networks, allowing straightforward installation on light industrial power systems. An IP20 protection rating permits mounting inside enclosed switchgear while still giving access to service terminals. The slim book-style housing conserves cabinet width, enabling high packing density when multiple drives are lined up on a DIN rail. Operators interact through a built-in display (SLCP) that presents parameter values, fault codes, and start-stop keys without external modules. The front interface keeps routine setup, local control access, and status checks in one place, which helps simplify day-to-day operation.

The remaining configuration details address standardized process duties rather than communication add-ons or protective upgrades. The unit ships without a fieldbus option, so speed reference and status feedback are handled through analog I/O or the front keypad. A dedicated process designation means the factory settings favor constant-torque loads common in mixers and agitators. The electronics are supplied without a coating, which suits clean, temperature-controlled spaces. The hardware is delivered in a standard build and includes no application option, leaving the configuration focused on the core drive functions.
