195N1039 by Danfoss

The 195N1039 is a variable-frequency drive manufactured by Danfoss for the VLT 2800 Low Voltage Drives series. Designed for cabinet installation, it modulates the voltage and frequency supplied to induction motors so that speed matches real-time process demands, which helps reduce energy use and startup stress. This control method allows connected motors to ramp smoothly during speed changes and maintain output that follows process requirements more closely than fixed-speed operation. The drive is suited to industrial automation lines where compact motor control and steady speed regulation are needed across multiple process points.

The unit accepts a supply of 380-480 V ±10% at 50/60 Hz and is intended for three-phase mains, which helps keep current draw balanced across the incoming conductors. Its nominal output is 1.5 kW, equivalent to 2.0 HP, which suits small pumps, mixers, and conveyor sections. A front-mounted built-in display (SLCP) allows local parameter entry, fault acknowledgment, and speed reference adjustment without external tools. The standard configuration uses uncoated printed circuit boards, and system interaction relies on discrete I/O or the keypad because no fieldbus option is installed.

The slim book-style housing lets multiple drives mount edge to edge, which helps conserve panel width in crowded control cabinets. An ingress protection rating of IP20 protects against accidental contact with live parts and is intended for use inside an enclosed cabinet with managed airflow. Conducted emissions are limited by an integrated filter that meets EN 55011 Class A1, which helps nearby instrumentation operate with less interference. The drive is supplied with no application option, so the option bay remains empty and wiring access stays straightforward during installation and service.
