Product Description:

The 195N1118 is a low-voltage variable-frequency drive produced by Danfoss for the VLT 2800 Low Voltage Drives series. It converts three-phase mains power into controlled output power that regulates induction motor speed in conveyors, pumps, and similar process equipment. An integrated DeviceNet port allows the unit to exchange set points and operating status with PLCs without requiring additional gateways. The drive also supports rapid deceleration during automated stop commands.

The drive is rated for 1.1 kW of continuous output, which corresponds to a mechanical shaft capacity of 1.5 HP. Under full load, it can deliver up to 24 A of phase current while dissipating 412 W as heat through its aluminum heat sink. Overall conversion efficiency reaches 97%, reducing the energy wasted as heat in ventilation-controlled cabinets. An IP20/NEMA 1 enclosure allows panel mounting in clean electrical rooms, and pluggable terminals accept three-phase input from 3 × 380–480 V AC with a ±10% tolerance. The internal brake transistor works with an external resistor that must have an impedance of at least 40 ohms. Because the drive does not include an integral RFI filter, external electromagnetic compatibility components can be added when required by installation codes. A built-in mechanical brake holds the load at a standstill, while the DeviceNet interface supports standard baud rates for cyclic data exchange.

The dynamic braking network can absorb up to 5.00 kW of regenerative energy, protecting upstream fuses and minimizing deceleration time. On the input side, the inverter draws 24.0 A at maximum load, so the branch circuit requires a 50 A fuse in accordance with the manufacturer’s requirements. Speed control remains stable across a line frequency range of 50/60 Hz with a tolerance of ±3 Hz, allowing operation with either utility standard. The assembly weighs 18.5 kg, which must be considered when selecting enclosure back panels, mounting hardware, and structural supports.
