Product Description

The FR-HEL-H75K is specifically engineered for Mitsubishi’s 400V class inverters, such as the FR-A840 or FR-F840 series, with a power rating of approximately 75kW. It is connected to the DC bus of the inverter to suppress harmonic currents generated by the rectifier circuit. By smoothing the DC current, it reduces the thermal stress on the DC bus capacitors and improves the overall power factor of the system.

Product Parameters

• Model Name: FR-HEL-H75K

• Voltage Class: 400V AC Class (typically used for 380V–480V systems)

• Applicable Inverter Capacity: 75 kW (100 HP)

• Inductance: Specifically tuned for 75kW ripple suppression

• Rated Current: Sized to handle the full load DC current of a 75kW inverter

• Cooling Method: Natural air cooling

• Enclosure Rating: IP00 (Open type, intended for installation inside a control cabinet)

• Standards Compliance: Designed to meet international electromagnetic compatibility (EMC) guidelines and harmonic suppression standards (like IEEE 519).

Product Advantages

• Harmonic Reduction: Significantly reduces the Total Harmonic Distortion (THD) of the input current, helping facilities meet utility requirements and preventing interference with sensitive electronic equipment.

• Power Factor Improvement: By smoothing the input current peaks, it improves the input power factor, potentially reducing electricity costs and allowing for smaller upstream fuses and cables.

• Inverter Longevity: Reduces the “ripple current” that flows into the inverter’s DC bus capacitors, which minimizes internal heating and significantly extends the lifespan of the drive.

• Compact Integration: Designed with a footprint that matches industrial cabinet layouts, allowing for efficient mounting near the associated inverter.

• High Reliability: Features a robust copper-winding and iron-core construction with no moving parts, ensuring a maintenance-free service life.

Important Considerations

• Heat Generation: Like all reactors, the FR-HEL-H75K generates heat during operation. It must be mounted vertically with sufficient clearance for air convection to prevent overheating.

• Proper Wiring: Ensure the DC reactor is connected to the correct terminals (typically P1 and P+ on Mitsubishi inverters). The shorting jumper between these terminals on the inverter must be removed before the reactor is connected.

• Voltage Drop: A small voltage drop occurs across the reactor. While usually negligible, it should be considered in applications where the input line voltage is already at the lower limit of the inverter’s tolerance.

• Weight and Safety: This component is heavy (due to the iron core). Ensure the mounting plate or DIN rail is rated for the weight and that it is securely fastened to avoid vibration-related damage.

Product Applications

The FR-HEL-H75K is essential in heavy industrial applications where large motor drives are used, including:

• Water & Wastewater: Powering high-capacity centrifugal pumps and aeration blowers where power quality is strictly monitored.

• HVAC Systems: Used in large-scale chillers and cooling towers in commercial buildings to prevent harmonics from affecting building electronics.

• Manufacturing Lines: Protecting drives in metal stamping, paper mills, and glass manufacturing where high-duty cycles are common.

• Infrastructure: Used in tunnel ventilation fans and lifting equipment where long-term reliability and grid stability are required.
