Product Description:

The 134F2994 is a Frequency converter used in motor speed control, particularly in HVAC, pumps, and fans, to improve energy efficiency and process control. A power output of 3.0 horsepower is generated by the FC-360H2K2T4E20H2BXC frequency converter, which has a rating of 2.2 kW.

The converter has an RFI Class A2 filter built in to make sure it meets the standards for electromagnetic compatibility. The control card is compatible with Profibus, which makes it possible for automated devices to engage in straightforward communication with one another. The 134F2994 frequency converter has a brake chopper that allows the user to decide how hard you brake. Standard software and a language pack that simplifies the process of setting up the converter are included in the package. The PCB is coated, which gives it extra safety. The converter has options for load sharing on the mains that allow processes to run in parallel. The design of the enclosure does not have any blind cover display options, and the cable entries are normal. Adaptation B is not part of the setup. The frequency converter belongs to the series of VLT® AutomationDrive FC-360.

To function properly, the frequency converter requires a three-phase supply power that ranges from 380V to 480V AC. The 134F2994 frequency converter weighs 2.86 kg when it is fully loaded and 2.5 kg when it is empty. For the EU, the ECCN code is Y901, and for the US, it is 3A999.a. The frequency converter is compact, and the chassis enclosure has international protection of 20. The setup makes it possible for demanding automation processes to run consistently. Standardized features built into the frequency converter make installation and setup easier.
