Product Description:

The 195N2190 is a frequency converter manufactured by Danfoss within the VLT 2900 Industrial Drives series. The unit converts fixed-frequency, three-phase mains power into a variable output that allows automation controllers to regulate motor speed and torque. Designed for machinery that requires moderate power, it drives induction motors used in conveyors, pumps, and general material-handling equipment, and it provides the electrical interface between plant supply networks and equipment requiring adaptable motion profiles.

Operational efficiency is rated at 96%, so only 4% of incoming energy is dissipated as heat, which helps contain the internal temperature rise. Protection is provided by an IP20 housing that shields live parts from fingers and similarly sized objects inside control cabinets. The drive maintains full performance at elevations up to 1000 m above sea level and supports shielded motor cables as long as 40 m without exceeding electromagnetic limits. During heavy acceleration, it can supply a peak phase current of 5.9 A for 60 seconds. Upstream protection must be coordinated with a 20 A semiconductor fuse or circuit breaker to protect the converter during electrical faults.

Continuous operation is supported by an apparent power capacity of 2.6 kVA at 400 V and a steady-state output current of 3.7 A, which correspond to a typical mechanical output of 1.5 kW. The unit draws a nominal mains input current of 3.2 A, a value used when sizing feeders and planning cabinet power distribution. The recommended motor lead cross section is 4 mm² (10 AWG), and total cable impedance must remain within the permitted range to maintain pulse fidelity. Power dissipation peaks at 75 W, so enclosure cooling must remove that heat while keeping the ambient temperature below 45 °C. The drive withstands vibration levels up to 0.7 g and operates at relative humidity levels up to 93%. Its mass of 2.1 kg reduces the structural load placed on the mounting panel.
