Product Description:

The 195N1059 is a variable frequency AC drive manufactured by Danfoss for the VLT 2800 Low Voltage Drives series. Installed between the mains supply and a three-phase induction motor, it modulates output frequency to control shaft speed, allowing tighter process control and reduced mechanical wear. The device is intended for light-duty automation such as small conveyors, fans, and pumps. It connects to supervisory systems through the built-in DeviceNet interface for parameter downloads and real-time diagnostics.

Its power stage is rated at 0.55 kW, a level suited to fractional-horsepower machines that require regulated speed control. During continuous operation, the input line draws 4.7 A and supplies the inverter section, which delivers a nominal motor phase current of 5.2 A. Conversion efficiency reaches 96%, so only 4% of the electrical energy becomes heat under the stated operating conditions. The drive has a true power factor of 0.90, which helps keep reactive power demand low. Five digital inputs accept start, stop, and preset speed commands, while a single relay output can transmit operating status to auxiliary equipment. The integrated EN 55011-1A filter attenuates radio-frequency interference and reduces conducted emissions on the supply lines.

The drive is housed in an IP20 open-type enclosure, so it must be mounted inside a switchboard that provides suitable protection against accidental contact. During overload events, it can supply up to 8.3 A for 60 seconds without tripping. The recommended upstream fuse rating is 20 A, and the short-circuit withstand capacity is 100,000 A. Thermal planning should account for 110 W of power loss at full load, and the three-phase terminals accommodate RFI-filtered cabling routed through the cabinet. The unit weighs 3.7 kg, which makes it easier to position and secure during panel assembly.
