Product Description:

The 195N1051 is an AC variable-frequency drive manufactured by Danfoss for the VLT 2800 Low Voltage Drives series. As a compact motor controller, it converts fixed three-phase mains power into a regulated output that allows automation systems to adjust induction motor speed without mechanical throttling. The unit is intended for conveyors, pumps, and similar process equipment where precise speed control improves energy use and reduces mechanical wear. Its compact design supports installation in control cabinets where available panel space is limited.

The drive has a power rating of 0.55 kW, allowing it to supply the connected motor continuously under normal operating conditions. Line-side demand reaches an input current of 4.7 A when the controller is fully loaded, while the inverter delivers an output current of 5.2 A. Overall conversion efficiency is 96%, so only a small portion of the incoming energy is dissipated as heat. A three-phase input simplifies connection to standard industrial mains. The IP20 plastic housing is suitable for cabinet mounting in clean areas, while an integral RFI filter attenuates conducted emissions at the source. Adequate cabinet ventilation should be provided to maintain proper operating temperatures around the drive.

The rectifier can draw up to 7.5 A for 60 seconds, and the inverter can supply 8.3 A for the same interval before current limiting becomes active. This short-term overload capacity supports motor acceleration and brief increases in process demand. At full load, the electronics dissipate 110 W, which must be considered when arranging enclosure airflow. Motor leads up to 4 mm² / 10 AWG can be connected to the output terminals, and upstream protection can be provided by a 20 A fuse. Five programmable digital inputs and one relay output provide basic sequencing and status control with a PLC. The drive has a mass of 3.7 kg, making it suitable for wall or panel mounting within an appropriately protected cabinet.
