195N1133 by Danfoss

The 195N1133 is an AC variable-frequency drive manufactured by Danfoss for the VLT 2800 Low Voltage Drives series. It is intended for panel installation, where it regulates motor speed instead of running a motor directly across the line. This method helps improve process consistency, reduce mechanical stress during operation, and lower power draw in equipment such as conveyors, mixers, pumps, and other continuous-duty industrial machines. The drive is suited to applications that need controlled acceleration and stable motor operation throughout normal production cycles.

The inverter supplies up to 18.5 kW of mechanical output, which corresponds to a nominal rating of 25 HP. It accepts 380-480 V with a ±10% tolerance at 50 or 60 Hz, allowing operation on common industrial mains without requiring a separate voltage conversion stage. Operation on a three-phase grid supports balanced current draw and stable torque response at the motor shaft. The enclosure has an IP20 rating, so it is intended for installation inside a ventilated electrical cabinet where fingers are protected and airflow remains unrestricted. This arrangement suits indoor control panels where the surrounding enclosure provides the main barrier against dust and moisture.

A Bookstyle form factor lets multiple drives share cabinet space with minimal side clearance, which helps when panel width is limited. The front-mounted built-in SLCP display provides direct parameter access without external tools, making routine setup and adjustment straightforward at the drive. The unit is supplied without an EMC filter on the input side, which suits installations where conducted emissions are managed elsewhere in the cabinet system. It is delivered in a standard hardware configuration with no application option, no fieldbus interface, and no conformal coating. This layout supports basic motor-control duties in enclosed cabinets that rely on standard ambient-air cooling.
