Product Description:

The 195N1039 is a low-voltage AC drive produced by Danfoss within the VLT 2800 Low Voltage Drives series. It modulates the speed of three-phase induction motors used in process machinery, providing controlled torque and energy savings without mechanical throttling. By converting fixed-frequency mains power into a variable-frequency output, the unit supports pumps, fans, and conveyors that require responsive speed adjustment. Its compact format also allows the drive to be installed in control cabinets where panel space is limited.

This model delivers a nominal output of 1.5 kW, which corresponds to 2.0 HP and supports small to medium motor frames commonly used on auxiliary equipment. The input section accepts a line supply of 380–480 V ±10% at 50/60 Hz, allowing operation when the supply voltage varies within the stated tolerance. A three-phase connection is required to provide balanced input current. The IP20 enclosure guards against contact with internal parts and prevents solid objects larger than 12.5 mm from entering, but a suitable cabinet is required when greater ingress protection is needed. No fieldbus option is installed, so commands and status signals are handled through discrete I/O or the integrated front panel. The internal components use the standard hardware configuration for this model.

An integral RFI filter complies with EN 55011 Class A1, limiting radio-frequency emissions when the drive operates on industrial mains. The slim book-style housing conserves panel width and permits side-by-side mounting with minimal derating when the required ventilation clearances are maintained. Parameter access is provided through a built-in display (SLCP), allowing local configuration and operating-status review without an external interface. The electronics are supplied with no protective coating, making the drive appropriate for clean, climate-controlled installations without significant exposure to moisture or airborne contaminants. The drive has no separate application option and uses a Process profile for proportional-integral speed regulation. This control arrangement supports variable-torque and constant-torque loads while retaining direct access to the drive’s primary operating parameters.
