195N0004 by Danfoss

The 195N0004 is a low-voltage AC drive manufactured by Danfoss as part of the VLT 2800 Low Voltage Drives series. This standalone converter modulates the incoming supply to control the speed and torque of small industrial motors in pumps, fans, and conveyors. By combining the control electronics, power stage, and operator interface in one narrow chassis, the unit fits control panels where space is limited and straightforward setup is important.

For electrical integration, the drive accepts a mains input of 200-240 V AC, which allows direct connection to common low-voltage distribution networks without an added transformer. It operates from a single-phase supply, which helps simplify wiring in small cabinets and auxiliary panels. The mechanical layout uses a book-style format, so multiple units can be mounted side by side while airflow remains available through the heat-sink channel. The enclosure carries an IP20 rating, which helps prevent contact with live parts by fingers and objects larger than 12.5 mm, although the drive still needs installation inside a switchgear cabinet for dust and moisture protection. Parameter entry and status messages are handled through the integrated built-in display (SLCP), so no separate keypad is required.

Electromagnetic compatibility is supported by an integrated RFI filter rated to EN 55011 Class A1, which suits industrial installations where nearby equipment may be sensitive to conducted interference. The unit is supplied in a standard configuration with brake, so it includes a brake chopper for dissipating regenerated energy during rapid deceleration. It is intended for process applications, so its default behavior favors stable speed control rather than cyclic positioning. There is no application option installed, and the drive also ships without a fieldbus option or protective coating.
