Product Description:

The 195N1050 is an AC variable frequency drive produced by Danfoss as part of the VLT 2800 Low Voltage Drives series. This compact converter regulates the speed of small induction motors in conveyors, mixers, and pump skids by modulating the supplied frequency and voltage. By integrating the motor controller, rectifier, and IGBT inverter into one housing, the unit provides precise torque control without external contactors. In factory automation, its primary role is to optimize energy use and provide closed-loop speed regulation for low-power motors.

At the motor terminals, the converter can deliver an output of 0.55 kW under nominal operating conditions. The input bridge withstands a peak current draw of 7.5 A, while the inverter section supplies up to 8.3 A to the motor during transient overloads. The drive has an IP20 enclosure that provides basic finger protection, so installation inside an industrial control cabinet is expected. Overall drive efficiency reaches 96%, helping limit losses during continuous operation. The unit has a true power factor of 0.90, which reduces reactive power demand from the supply. Five programmable digital inputs allow a PLC to select preset speeds or issue start, stop, and jog commands. An integral brake chopper supports shorter deceleration ramps when the connected motor drives a high-inertia load.

Power loss remains limited to 110 W, helping keep the enclosure temperature rise within cabinet ventilation limits. For upstream protection, the feeder can be fused at 20 A. The drive is rated for use on a supply system with a prospective short-circuit current of up to 100,000 A when protected by the appropriate fuse. The assembled unit weighs 3.7 kg, reducing the structural support required for bulkhead or similar panel installation. Rated input and output currents of 4.7 A and 5.2 A, respectively, support continuous operation. Efficient heat sinking transfers thermal energy from the power electronics to the surrounding cabinet air.
