Product Description:

The 134F3028 is an AC variable frequency drive produced by Danfoss for the VLT FC 360 Automation Drives series. In an automation cell, it converts fixed-frequency mains power into a controlled waveform that adjusts motor speed and torque according to real-time process commands. This variable-speed operation can reduce energy consumption in pumps, fans, and conveyor systems while eliminating the need for mechanical flow-control devices. The drive can also respond to changing production requirements without requiring manual adjustments to the connected motor or driven equipment.

The drive accepts a three-phase input of 380–480 VAC and can deliver up to 15 kW of electrical power, which corresponds to approximately 20 HP at the motor shaft. It supports normal overload operation, allowing 110% current during short starts without requiring output derating. A built-in brake chopper dissipates regenerative energy during abrupt deceleration, helping protect the DC link from excessive voltage. The IP20 chassis protects against contact with internal components but does not provide protection from water. Installation inside a properly ventilated enclosure is therefore required to shield the drive from moisture and excessive contamination.

Electrical integration is simplified by standard cable entries on the housing, which provide organized routing for power and control conductors. The printed circuit boards have a protective coating that helps guard the control electronics against dust, humidity, and airborne contaminants inside industrial panels. When several inverters share a common DC rail, the load-sharing option allows deceleration energy to be distributed among the connected units. Conducted emissions toward the power supply are limited by the built-in RFI Class A2 filter, supporting operation within general-purpose industrial limits. Control functions are handled by a standard control card, and the standard language pack provides the available user text. The unit is supplied without a display, leaving the display slot available for a compatible interface when local operation or parameter viewing is required.
