Product Description:
The 195N1079 is a low-voltage AC drive produced by Danfoss for the VLT 2800 Low Voltage Drives series. As a compact frequency inverter, it converts three-phase mains power into variable-frequency output that allows control systems to regulate induction motor speed and torque in automated conveyors, pumps, and material-handling stations within industrial plants. It occupies the lower power range of the series, providing a compact installation option when precise speed regulation is required without the footprint of larger drive cabinets.
The drive accepts a three-phase input of 3 × 380/400/415/440/480 V ±10% and operates at a supply frequency of 50 or 60 Hz with a 3% tolerance, allowing use on common industrial power systems. Under rated conditions, it draws 8.1 A and delivers a continuous output current of 9.1 A to the motor, matching the 1.0 HP mechanical output associated with this frame size. Its electrical efficiency of 96% limits heat generation, while a built-in Class 1A RFI filter suppresses conducted emissions. Five digital inputs support local start, stop, and preset-speed commands, and the integrated Profibus DP interface connects the unit to higher-level PLCs. The IP20 open-chassis enclosure provides basic protection against finger contact in panel-mounted installations. A 20 A upstream fuse is recommended for circuit protection, and the design withstands network fault currents of up to 100,000 A without case rupture.
The inverter provides a continuous output of 0.75 kW, while momentary overload demands are supported by a peak current of 14.5 A for up to 60 seconds. Full-load power loss is 200 W, so cabinet ventilation must remove the resulting heat to keep internal semiconductor temperatures within operating limits. The unit weighs 3.7 kg, which reduces the load placed on swing-out panels and simplifies physical handling during installation. Its compact enclosure is suitable for restricted panel spaces that still require moderate motor power, fieldbus connectivity, and short overload capability.
