Convertisseur de fréquence Danfoss 132L6122 iC2-30 5,5 kW

Overview

The 132L6122 (132L6122) is a high-efficiency iC2-30 Frequency Converter Air Cooled designed for precision motor control in diverse industrial environments. This compact drive, part of the next-generation Danfoss iC2 series, supports three-phase power inputs ranging from 380-480 V AC and provides a steady 12.0 A output, equivalent to 5.5 kW (7.5 HP). Engineered to replace complex motor starters in applications such as material handling, fans, and pump systems, the 132L6122 integrates a built-in brake chopper to handle regenerative energy during rapid deceleration. Its air-cooled design and IP20/Open type protection rating make it an ideal choice for cabinet-mounted installations where space optimization and reliable thermal management are critical for reducing system downtime.

Hardware Configuration & Model Breakdown

The technical identity of the 132L6122 is defined by its specific configuration string: IC2-30FA3N04-12A0E20F4+ACBC. Each segment represents a critical performance parameter:

• Standardized Power Conversion: The 3N designation signifies a Three-phase output, providing balanced torque for industrial induction motors.

• Voltage Dynamics: Optimized for 04 (380-480 V AC) mains, allowing for global deployment across various power grids.

• Braking Efficiency: The +ACBC suffix indicates an Integrated Brake Chopper, allowing for the connection of external resistors to manage kinetic energy without tripping the drive.

• EMC Suppression: Equipped with a F4 (C4 Category) filter, the unit is designed for use in industrial environments where electromagnetic compatibility is managed at the system level.

Technical Specifications

Technical FAQs

Does the 132L6122 require an external brake chopper?

No. This model is factory-equipped with an Integrated Brake Chopper (+ACBC). You only need to connect a suitably sized external brake resistor to the designated terminals if your application involves high-inertia loads or fast ramps.

What is the maximum ambient temperature for reliable operation?

The 132L6122 is designed for operation up to 50 deg C. However, for optimal longevity and to avoid automatic current derating, it is recommended to maintain a cabinet temperature below 45 deg C with proper ventilation.

Can this drive be used in a residential area?

The F4 (C4 category) EMC rating is intended for industrial networks. If installation in a residential (Category C1 or C2) environment is required, additional external RIF/EMC filters must be installed to prevent interference with other electronic equipment.

Engineering & Installation Strategy

• Airflow Clearance: To ensure the Air Cooled system functions efficiently, maintain at least 100 mm of clearance above and below the drive. For side-by-side mounting, refer to the manual for specific zero-clearance distance requirements to prevent thermal hotspots.

• Cabling Precision: Use shielded motor cables to maintain EMC compliance. Ensure the shield is grounded 360 degrees at both the drive and the motor end to minimize high-frequency noise interference with nearby PLC or sensor signals.

• Brake Resistor Protection: When using the integrated chopper, ensure the brake resistor is equipped with a thermal switch. This switch should be interlocked with the drive's enable circuit or the main contactor to prevent fire hazards in the event of a chopper short-circuit.

Engineering Advantages

The Danfoss 132L6122 excels in simplicity and robustness. Its 3.1 kg frame houses a high-torque control algorithm that provides excellent shaft performance even at low speeds. The IP20 enclosure is designed for high-density side-by-side mounting, significantly reducing the required cabinet footprint. Furthermore, the iC2 series utilizes enhanced coating on the printed circuit boards (PCBs) to resist humidity and dust, ensuring a long service life in demanding industrial sectors like textile manufacturing and woodworking.
