Product Description:

The 195N0055 is a low-voltage AC drive produced by Danfoss for the VLT 2800 Low Voltage Drives series. The unit converts single-phase mains power into a variable-frequency output that allows small induction motors to operate at controlled speeds in conveyors, pumps, or packaging machines. Its purpose in an automation cell is to match motor speed to process demand, reduce energy use, and limit mechanical wear while occupying minimal panel space. Because it targets motors below one horsepower, the drive simplifies retrofit projects where a three-phase power supply is not available.

The motor output is rated at 0.55 kW, providing sufficient capacity for fractional-horsepower machines. On a single-phase input, the typical line demand is 15.2 A, while the controller can tolerate a momentary input current of 24.3 A during ramp-up. The inverter delivers a rated output of 6.8 A to the motor terminals and can supply 10.8 A during short overloads without tripping. Conversion efficiency reaches 95%, which limits heat dissipation to the documented power loss of 94 W at full load. A true power factor of 0.90 keeps upstream wiring currents close to the real-power requirement. A 20 A upstream fuse protects the supply against internal faults.

The drive uses an IP20 open-frame enclosure intended for installation inside a switchboard, and it weighs only 2.0 kg, easing DIN-rail or backplate mounting. Motor leads up to 4 mm²/AWG 10 can be connected to the output terminals without auxiliary adapters, allowing the existing conductor size to be accommodated directly. When the recommended fuse class is applied, the design can withstand a prospective short-circuit current of 100,000 A. This fault-current capacity supports installation on power systems with substantial available current, while the enclosure still requires the protection of a suitable cabinet. The compact housing also helps preserve wiring space around adjacent control equipment and terminal blocks.
