Product Description:
The 134U2979 is a variable-frequency drive manufactured by Danfoss for the VLT FC 280 Midi Drives series. It is designed for installation inside an IP20 control cabinet, where it regulates the speed of three-phase induction motors in light-to-medium-duty automation. By producing an adjustable output frequency from the incoming AC supply, the drive translates PLC commands into controlled motor speed and torque. Its compact design supports conveyor, pump, and fan systems where available cabinet space is limited and consistent motor regulation is required.
This model delivers a nominal shaft power of 0.75 kW, which corresponds to 1.0 HP. It operates from a three-phase 380–480 VAC mains supply, making it suitable for common industrial power systems within that voltage range. The IP20 chassis protects against accidental contact with hazardous internal components, but the drive requires a suitable enclosure where dust or liquids may be present. An integrated EMC Category C1 at 200 V and Category C2 at 400 V RFI filter reduces conducted electrical interference. This filtering helps limit noise transmitted from the switching power stage into the connected supply network and nearby electrical equipment.
A built-in brake chopper controls regenerated energy during rapid motor deceleration by switching that energy to a compatible braking resistor. Motor regulation and communication are handled through a standard control card with Modbus, allowing the drive to exchange commands and operating data with compatible control systems. The power circuit board has a protective coating that guards its conductive traces against condensation and airborne contaminants. The unit has no display, so parameters and operating information are accessed through compatible software rather than a local screen. A preinstalled standard language pack supports software-based configuration, while the baseline electrical arrangement avoids additional adaptation hardware and dedicated mains accessories.
