Product Description:

The 195N1087 is an AC variable frequency drive produced by Danfoss for the VLT 2800 Low Voltage Drives series. Belonging to the broader VLT product group, the unit regulates induction motor speed in continuous process lines, pumps, and general automation. Its compact, book-style design allows installation in crowded control cabinets, while its pulse-width-modulated output provides controlled motor torque. In plants that require stable throughput, the device converts three-phase mains power into a variable-frequency output, allowing motor speed to be adjusted without mechanical throttling. This electronic control method can reduce unnecessary energy consumption when an application does not require the motor to operate continuously at full speed.

Rated at 7.5 HP, the drive can supply induction motors that require moderate mechanical power while maintaining efficient operation. Its continuous electrical capacity is 5.5 kW, which is the maximum output the inverter can deliver without derating at the stated ambient cabinet temperatures. The input section accepts 380–480 V, ±10%, 50/60 Hz utility power and is configured for a three-phase network, so no external transformer is required on a compatible industrial grid. An IP20 protection rating provides finger-safe access but requires the drive to be installed inside a closed control panel. Appropriate panel ventilation and installation clearances are necessary to prevent excessive heat from reducing the drive’s available output. The power input and motor output wiring should also follow the applicable grounding and circuit-protection requirements for the installation.

For electromagnetic compatibility, the integrated filter meets EN 55011 Class A1, reducing conducted electrical noise on supply lines in factory installations. The slim book-style housing supports side-by-side mounting without additional lateral clearance, allowing a high packing density inside the enclosure. A built-in display (SLCP) provides local readings for speed, current, operating status, and alarm codes without requiring a separate keypad. The drive is supplied in a standard configuration with no application option or fieldbus option installed. Its circuit boards do not have a protective coating, so the enclosure should prevent exposure to condensation, conductive dust, and corrosive airborne contaminants. Local controls provide direct access to operating information, while external control signals can regulate the connected motor as part of an automated process.
