3-phase sinusoidal output filter for a 2.2 kW inverter SinECO-2,2/6 SINECO-2,2/6

Sine filter output – inverter performance optimization

This three-phase sine filter, designed to work with 2.2 kW inverters, is a key element in improving power quality and extending the life of connected devices. Its task is to restore the sinusoidal shape of the voltage at the inverter output, which directly affects the stable and efficient operation of motors and reduces interference in the network. The SinECO-2.2/6 filter has been designed for demanding industrial applications where reliability and minimizing energy losses are a priority.

Construction and application

The SinECO-2.2/6 sine filter is dedicated to drive systems powered by voltage inverters. Its main goal is to eliminate harmonics and improve the power factor, which translates into a number of benefits for the entire system. The chokes, an integral part of the filter, are made in low-loss technology, which minimizes energy losses and reduces device heating. The filter design allows parameters to be adapted to the specific needs of the drive system – both in terms of switching frequency and voltage and current.

Advantages and benefits of use

• Motor and cable protection: Restoring the sinusoidal shape of the voltage limits the degradation of the motor and power cable insulation, extending their life and reducing the risk of failure.
• Reduced energy losses: The filter minimizes additional energy losses in the motor, which translates into lower operating costs and increased energy efficiency of the entire system.
• Noise reduction: Improved power quality affects the reduction of noise generated by the motor during operation.
• Inverter relief: Eliminating parasitic capacitive currents relieves the inverter, increasing its reliability and extending its service life.
• Adaptation to needs: The ability to adapt the filter parameters to specific drive system requirements ensures optimal performance in various applications.
• Durable construction: The filter is designed to operate in harsh industrial conditions – the degree of protection is IP00 (optionally IP23, IP44 or IP54) provides resistance to external factors. Winding material is copper (Cu).
• Easy installation: Installation is done with screws through angle brackets, which facilitates installation and servicing of the device.
• Compliance with standards: The filter meets the requirements of technical standards PN-EN 60076-6 and PN-EN 61558-2-20.

The SinECO-2.2/6 filter is an investment in the reliability and efficiency of the drive system – both for installers looking for proven solutions and for end users expecting long-term and trouble-free operation of their devices.
