Convertisseur de fréquence Danfoss 131G1413 VLT HVAC Drive FC 102

Product Overview

The Danfoss 131G1413 (FC-102P75KT4E66H2XGXXXXSXXXXAXBXCXXXXDX) is a high-performance 75 kW frequency converter engineered to deliver optimized process control for mission-critical HVAC applications. As a core member of the VLT HVAC Drive FC 102 series, this drive is designed to minimize lifecycle costs through advanced energy optimization and intelligent automation. Capable of controlling multiple high-efficiency permanent magnet motors in parallel, this drive ensures seamless integration into modern building management systems, effectively reducing operational overhead and ensuring compliance with stringent environmental regulations without the need for external cooling or oversized hardware.

Technical Configuration

This 75 kW unit is designed for reliable three-phase operation. It features a robust, modular hardware architecture that eliminates the requirement for external control and conversion equipment by integrating specific functionality for pumps, fans, and compressors. The device includes a graphical Local Control Panel (LCP-102) for intuitive programming and a built-in energy meter compliant with NABERS standards. To ensure electromagnetic compatibility in commercial installations, the unit comes equipped with a factory-integrated RFI Class A2 filter. The drive also includes a Smart Logic Controller, which frequently negates the need for external PLC capacity, simplifying the control infrastructure.

FAQs

How does the Automatic Energy Optimization (AEO) function work?

The AEO function continuously monitors the motor load and adjusts the magnetizing current to the absolute minimum required for the task. This results in an automatic 5-15 percent energy saving compared to standard VFD operation, particularly in partial-load fan and pump scenarios.

Is external cooling required for this drive?

No. The FC 102 is designed for high-temperature resilience, allowing for full-load operation in ambient temperatures up to 50 deg C without derating, which avoids the need for expensive external cooling systems or over-sizing the drive hardware.

Does this drive require external energy metering?

No, the built-in energy meter is NABERS-compliant, providing real-time power consumption data directly to the building management system, which reduces system complexity and installation costs.

Are standard HVAC communication protocols supported?

Yes, both Modbus and BTL-listed BACnet are included free of charge. These protocols allow for quick and easy integration into existing BMS architectures, enabling the transfer of operational data points and setpoints with minimal setup time.

Installation Guidelines and Best Practices

• EMC Compliance: Out-of-the-box compliance with IEC 61800-3 Category C1 is achieved by correctly bonding the motor cable to the motor terminal. Ensure that the motor cable shield is terminated using a 360-degree clamp at both the drive and the motor to maintain the required EMC integrity.
• Commissioning with Smart Start: Utilize the built-in Smart Start guide for the initial setup. This tool provides a step-by-step walkthrough in plain language, significantly reducing commissioning time and ensuring that all critical parameters are correctly aligned with your specific application.
• Maintenance of Uniform Interface: The VLT HVAC Drive FC 102 utilizes a unified interface across the 1.1 kW to 1400 kW power range. If your facility utilizes multiple drives of varying sizes, the programming logic remains consistent, allowing your maintenance team to manage the 75 kW unit with the same efficiency as smaller 3 kW models.
