195N0037 by Danfoss

The 195N0037 is a low-voltage AC drive produced by Danfoss in the VLT 2800 Low Voltage Drives series. As a variable-frequency inverter, it regulates the speed of small induction motors used in pumps, mixers, and other continuous-process equipment on factory floors. By modulating output frequency and voltage, the unit allows precise adjustment of motor torque to match changing load requirements, improving energy efficiency and helping protect mechanical components in industrial automation tasks that require consistent throughput.

Its output stage is rated for 1.1 kW of continuous mechanical power, which corresponds to 1.5 HP at the motor shaft, so the controller suits fractional-power motors commonly used on auxiliary plant equipment. The input section tolerates a supply window of 200-240 V AC, allowing the same model to operate on global low-voltage networks without tap changes. Cooling air circulates across a slender book-style housing that simplifies dense side-by-side mounting inside panels. An internal conduit shields live parts, yet the overall assembly carries an IP20 rating, which allows finger-safe access while still requiring installation in a clean, closed cabinet.

Control interaction is handled through a built-in display (SLCP) that shows speed, current, and alarm codes without requiring an external keypad. The core electronics use a standard hardware configuration, and no application option card is installed, which keeps parameter sets straightforward for general-purpose use. For installations that rely on analog or hard-wired control, the unit has no EMC filter, so external line filters must be added where conducted emission limits apply. The drive is intended for process applications and is supplied without coating, making it suitable for clean indoor switchrooms.
