195N1025 by Danfoss

The 195N1025 is a variable frequency drive manufactured by Danfoss and supplied through the VLT 2800 Low Voltage Drives series. It is installed between the mains supply and an induction motor to modulate voltage and frequency, giving precise speed control without mechanical throttling. By matching motor output to process demand, the drive supports smoother acceleration and steadier operation in pumps, fans, and conveyors.

This model delivers 1.5 HP of mechanical output, equivalent to a continuous electrical rating of 1.1 kW. It accepts line power in the range of 380-480 V ±10% 50/60 Hz, allowing the same unit to run on common three-phase grids worldwide. Internally, the converter is wired for three-phase input and output, so balanced current sharing is maintained across motor windings. Its terminals are finger-safe and housed inside an enclosure carrying an IP20 protection rating, which blocks accidental contact with live parts but requires installation inside a cabinet for dusty or splash-prone areas. These electrical limits suit pumps, fans, or conveyors that need moderate torque with low harmonic distortion on the supply.

The mechanical format follows a book-style layout, so several drives can mount side by side with minimal panel depth when multiple units share the same cabinet. A built-in display (SLCP) sits on the front plate and shows setpoint, actual speed, and diagnostic codes without needing external tools. The unit is supplied without an EMC filter, so any electromagnetic compliance must be handled by cabinet-level filters if required by plant standards. The power section is assembled without a protective coating, so the surrounding air should remain free of corrosive vapors. A standard hardware configuration, no application option, and the absence of a fieldbus interface simplify ordering when only analog or hardwired control is needed for process-duty applications.
