195N0019 by Danfoss

The 195N0019 is an AC variable-speed drive produced by Danfoss for the VLT 2800 Low Voltage Drives series. Acting as a compact frequency converter, it regulates motor speed and torque so that conveyors, pumps, or fans in process plants operate only at the rate demanded by the control system instead of running at a constant line speed. By adjusting output frequency and motor voltage to match changing load conditions, the unit supports smoother starts, steadier running under variable demand, and lower energy use than fixed-speed operation at full mains frequency in ventilation, fluid-handling, and material-moving equipment.

Electrically, the drive accepts 200-240 V AC from a single-phase supply, allowing installation on service panels that do not provide three-phase power and making it suitable for smaller utility feeds. Its inverter section delivers 0.55 kW, equivalent to 0.75 HP, which suits small centrifugal pumps, light conveyors, metering equipment, and other modest motor loads. The housing carries an IP20 rating, so only basic finger protection is provided and the unit must be mounted inside a cabinet to shield it from dust and incidental contact. The control setup is optimized for process applications, uses a standard hardware configuration, and has no application option installed.

The mechanical layout follows a book-style format, allowing several drives to be lined up with minimal clearance and a consistent airflow path inside the enclosure. A built-in display (SLCP) presents speed, current, and alarm data, so routine status checks and parameter viewing can be done at the front of the unit without an external programmer or separate keypad module. Conducted emissions are limited by an internal filter certified to EN 55011 Class A1, which supports installation in panels located near control and instrumentation equipment. The electronics are supplied without a coating, so the control panel should remain dry and free of corrosive vapors during storage and operation.
