195N1109 by Danfoss

The 195N1109 AC drive is built by Danfoss for the VLT 2800 Low Voltage Drives series. As a book-sized controller, it modulates the frequency and voltage supplied to three-phase induction motors used in process automation. This allows pumps, fans, and conveyors to run at speeds that better match real-time demand while reducing wasted energy and mechanical wear on the driven system. Speed control through the inverter also helps smooth starting and stopping on loads that do not need full motor speed at all times.

This model delivers a continuous power rating of 11.0 kW, which suits medium-duty machinery that needs solid output in a compact drive package. The motor rating is also expressed as 15 HP, which is the common imperial equivalent for the same output class. The input window of 380-480 V ±10% 50/60 Hz allows operation on common industrial mains, and the unit is wired for three-phase supply so input current is shared more evenly across the line conductors. This operating range gives the drive flexibility in facilities that use either 50 Hz or 60 Hz utility power. A protection category of IP20 helps guard against accidental contact with live internal parts, so the drive is intended for installation inside an enclosure or electrical cabinet.

Physical configuration supports tight cabinet rows through the slim Bookstyle housing, which leaves room for cooling airflow between adjacent units. Its narrow enclosure shape is useful in panels where several drives must be mounted side by side without wasting space. Operators interact locally through a built-in display (SLCP), and the screen shows frequency references, status messages, and basic fault information without requiring a separate keypad. The drive is supplied without an EMC filter, so any radio-frequency suppression is handled by an external filter selected for the installation. Internally, it uses the Danfoss Standard configuration, so the I/O arrangement and thermal behavior follow the baseline setup used for general process applications.
