195N1098 by Danfoss

The 195N1098 is a low-voltage AC variable frequency drive manufactured by Danfoss and supplied within the VLT 2800 Low Voltage Drives series. It is used in industrial automation to regulate the speed and torque of AC induction motors that drive conveyors, pumps, and similar process equipment. By adjusting output frequency relative to the incoming mains supply, the unit supports precise motor control, lower energy use, and reduced mechanical wear on connected machinery. This helps the motor start and stop more smoothly while keeping process speed closer to the commanded value.

This model is rated for 10 HP, which is equivalent to 7.5 kW, so it can handle medium-sized loads in auxiliary process duties. The accepted mains range of 380-480 V ± 10% 50/60 Hz supports installation on common international power systems, and the drive uses a three-phase input to keep conductor current balanced. An enclosure rating of IP20 helps protect against accidental contact with live parts while leaving the chassis vented for convection cooling. This version has no application option card, no fieldbus expansion, and no conformal coating, so it is intended for standard cabinet installations that do not require added communication functions or extra surface protection. Because cooling is passive, the drive depends on cabinet airflow and clear vent paths rather than a sealed housing.

The enclosure uses a book-style format, which allows multiple units to mount side by side while using minimal cabinet width. A built-in display (SLCP) provides local access to operating parameters and status information without external tools. The hardware is standard with brake, which means an integrated brake chopper is included to support rapid deceleration of high-inertia loads. This arrangement is useful where braking energy must be managed during short stopping times or repeated deceleration cycles. The unit is supplied without an EMC filter, so any required RFI suppression must be added externally.
