Product Description:

Included in the VLT FC 280 Midi Drive family is the small variable-speed drive Danfoss 134U2978, which is used in a number of manufacturing processes where reliable motor regulation is required.

This type's 0.55 kW (0.75 HP) rating of power makes it perfect for tiny motor systems that need constant effectiveness, energy efficiency, and accurate speed control. It uses a three-phase input voltage of 380-480 VAC, which is a common industrial power supply, and has an IP20 chassis-style enclosure to be mounted in a cabinet in a secure place. The drive is fitted with a C2-class EMC filter (at 400 V) to enable its compatibility to electromagnetic standards and safe interconnection with industrial networks. An internal brake chopper is also provided that improves braking performance in those applications where quick braking or a load stop is needed.

A coated PCB also helps to further protect the electronics, enhance resistance to dust, moisture, and other environmental contaminants, which enhances long-term reliability. To communicate and integrate, the 134U2978 is Modbus-compatible by default, and it is easy to interface with standard automation systems. With a constant electrical rating of 1.7 A in high overload (HO) mode, which permits momentary overload up to 160 percent for 60 seconds, the drive can effectively manage fluctuations in load. The drive has a broad speed range, 0 to 500 Hz, so it can be flexible with other motor types and applications. With a frame size of K1, a gross weight of 3.04 kg, a net weight of 2.61 kg, and an extremely simple installation process, it is physically small and light. It can be purchased at Wake Industrial with a one-year warranty.
