FC101P30KT4E20 Danfoss VLT HVAC Basic Drive 30 kW

Product Overview

The FC101P30KT4E20 (FC101P30K) is a dedicated VLT HVAC Basic Drive engineered for high-capacity motor control in professional ventilation, heating, and cooling systems. Delivering 30.0 kW (40.0 HP) of power, this frequency converter is optimized for driving large-scale centrifugal fans and pumps in commercial infrastructures like shopping malls, airports, and industrial complexes. The FC101P30KT4E20 is designed to maximize energy efficiency, boasting a 97.0% efficiency rating. By replacing traditional dampers or valves with variable speed control, it significantly reduces operational energy costs and mechanical wear. Its IP20/H7 enclosure is built for centralized cabinet installation, providing a compact footprint for high-power applications where thermal management and reliability are paramount.

Technical Configuration

The FC 101 HVAC Basic series features a robust hardware architecture tailored for long-term performance. It includes built-in functions such as the VVC+ (Voltage Vector Control) for superior motor shaft performance and a Sleep Mode to further enhance energy savings during low-load periods. The unit is equipped with a specialized cooling system that utilizes a forced-air heat sink to maintain stability even at 40 deg C ambient temperatures. It supports large-gauge wiring with terminals accommodating up to 50 mm2 (1 AWG) cables, ensuring secure high-current connections. Additionally, the drive integrates an automatic energy optimizer (AEO) and a flying start feature, allowing it to pick up a spinning fan without tripping, which is essential for large-scale HVAC ventilation loops.

Technical Specifications

Technical FAQs

Does the FC101P30KT4E20 include an integrated harmonic filter?

Yes, the VLT HVAC Basic series includes built-in DC link reactors that significantly reduce harmonic distortion (THDi) in accordance with IEC/EN 61000-3-12 standards, protecting the local power grid and sensitive equipment.

Can this 30 kW drive be used in high-temperature environments?

The drive is rated for full performance at 40 deg C. It can operate up to 50 deg C, but the continuous output current must be derated to 103.5 A to prevent internal thermal overload and ensure component longevity.

Is it possible to use this drive with permanent magnet motors?

The FC 101 series is primarily designed for high-efficiency asynchronous induction motors. While it provides excellent control for these motors, for PM motor applications, verify the specific software release or consider the VLT HVAC Drive FC 102 series.

Engineering & Installation Guide

Thermal Clearance and Cabinet Airflow: Given the 1015 W typical power loss at full load, the FC101P30KT4E20 requires significant airflow. Maintain a minimum of 200 mm clearance above and below the drive for vertical convection. Ensure the cabinet ventilation fans are rated to handle the heat dissipation to keep the ambient temperature within the 40 deg C nominal range.

High-Current Termination: For the 115.0 A continuous load, use high-quality copper conductors. Ensure the terminal screws are tightened to the torque specifications provided in the manual (approx. 4.5 Nm for this frame size) to prevent hotspots caused by high contact resistance, which can lead to terminal block failure.

Motor Cable Length and Shielding: To ensure EMC compliance and protect motor windings from dV/dt voltage peaks, use shielded cables. If the motor cable length exceeds 50 meters, the installation of an output dV/dt filter is recommended to prevent premature insulation breakdown in the 30 kW motor.
