195N1004 by Danfoss

The 195N1004 is a low-voltage AC drive manufactured by Danfoss and assigned to the VLT 2800 Low Voltage Drives series. Designed for compact panel installations, it uses a book-style enclosure that measures only 75 mm in width, allowing dense side-by-side mounting. That narrow format helps conserve panel space when several small drives are installed in the same enclosure. A built-in SLCP display provides local status and access to operating parameters. By modulating the output frequency delivered to a connected three-phase induction motor, the unit enables speed regulation in process automation lines.

For electrical sizing, the drive carries a power rating of 0.55 kW, which is equivalent to 0.75 HP, so it suits small pumps, fans, or mixers. With a rated output current of 1.3 A, it matches motors whose full-load current falls in that range. The input network may supply 380-480 V ± 10% 50/60 Hz; internal rectification and IGBT switching then create a variable output for the connected three-phase load. The enclosure is classified as IP20, so the unit requires cabinet installation for protection against moisture and debris. An EN 55011 Class A1 RFI filter limits conducted emissions, and full torque is available up to 1000 m altitude without derating.

In plant environments, the converter can produce an apparent power of 1.1 kVA while operating at ambient temperatures up to 45 °C. Mechanically, it resists sinusoidal vibration up to 0.7 g, which suits pump skids and conveyor frames. The aluminum chassis weighs 2.1 kg and measures 200 mm high by 168 mm deep, so it fits shallow control cabinets. The standard design omits conformal coating and fieldbus expansion cards, keeping the hardware focused on basic speed-control duties. This version is suited to general-purpose installations that use the drive inside a protected enclosure.
