134F2982 Danfoss VLT AutomationDrive FC 360 18.5 kW

Product Overview

The 134F2982 (134F2982) is a high-performance VLT AutomationDrive FC 360 frequency converter, specifically engineered for precision motor control in demanding industrial environments. With a power rating of 18.5 kW (25 HP) and a high overload (H) design, this drive is built to handle heavy-duty startup torques and fluctuating loads typical in manufacturing and process industries. The 134F2982 is an ideal solution for applications such as conveyor systems, mixers, and heavy-duty pumps, providing a balance of compact design and robust electrical performance. Featuring coated PCBs (Class 3C3) and a built-in brake chopper, it ensures high reliability and operational safety even in harsh conditions characterized by chemical moisture or rapid deceleration requirements.

Technical Specifications

Technical FAQs

Can the 134F2982 be used in environments with high humidity or chemical exposure?

Yes. The "C" suffix in the configuration indicates that the PCBs are coated. This provides superior protection against dust, moisture, and corrosive chemical vapors, making it suitable for wastewater treatment or chemical processing plants.

Does this model include a local control panel (LCP)?

No. The "X" in the display position indicates this unit is shipped without a display. For commissioning or local monitoring, an external LCP must be connected, or the drive can be configured via a PC using the Danfoss VLT Motion Control Tool MCT 10.

What is the purpose of the integrated Brake Chopper?

The integrated brake chopper allows the drive to connect directly to an external braking resistor. This is essential for applications with high inertia that require rapid deceleration, as it allows the drive to dissipate regenerative energy safely without triggering a DC-link overvoltage trip.

Engineering & Installation Guide

• Loadsharing Configuration: This unit (D option) supports loadsharing via the DC bus. When connecting multiple drives in a loadsharing setup, ensure that the DC-link fuses are sized correctly and that the voltage potential between the drives is synchronized to prevent circulating currents that could damage the capacitors.

• Cabinet Thermal Management: Since this is an IP20/E20 chassis unit, it must be installed in a protected control cabinet. With an 18.5 kW power rating, the drive generates significant heat at full load. Ensure the cabinet has forced ventilation and maintain a minimum vertical clearance of 100 mm above and below the drive to facilitate proper airflow through the heat sink.

• RFI/EMC Compliance: The integrated H2 RFI filter meets Class A2 standards. To maintain this compliance, motor cables must be shielded and the shield must have 360-degree contact with the ground plate. Ensure the motor cable length does not exceed the maximum specified for Class A2 to prevent electromagnetic interference with sensitive control electronics.
