Product Description:

The 195N2189 industrial AC drive is produced by Danfoss and belongs to the VLT 2900 Industrial Drives series. This variable-frequency device modulates the voltage and frequency supplied to a three-phase induction motor so that plant operators can adjust shaft speed in line with process demand. By replacing mechanical throttling with electronic control, the drive supports energy-efficient operation of pumps, fans, and material-handling equipment in automated production lines. Its compact enclosure allows installation inside standard control cabinets.

During continuous operation, the drive draws an input line current of 2.6 A, a figure that rises to 4.2 A for up to 60 seconds when the application demands brief overload torque. The inverter converts this supply into a motor phase current of 3.0 A, delivering up to 2.0 kVA of apparent power at 400 V. Heat produced by the IGBT stage is limited, and overall conversion efficiency reaches 96 %, so only a small portion of the incoming energy is dissipated as waste heat. The electronics are housed in an IP20-rated frame, providing finger-safe protection and enabling mounting inside ventilated electrical panels. Five programmable digital inputs and one analog output support local sequencing and feedback to higher-level controllers without extra interface modules.

During startup or braking events, the unit can supply 4.8 A of output current for 60 seconds, supporting motor acceleration without tripping the drive. Protection coordination is simplified by a recommended upstream fuse rating of 20 A and a tested short-circuit withstand rating of 100,000 A. Heat rejection under full load is 55 W, which can be removed by the normal airflow inside the cabinet. Terminals accept 4 mm² (10 AWG) conductors for both motor and mains leads, keeping wiring consistent across the installation. Despite its metal chassis, the drive weighs only 2.1 kg, so it adds little mass to a control enclosure.
