Sine wave filter

Product catalog summary

Company Overview
Shenzhen Sikes Electric Co., Ltd. is a leading provider of electrification, automation, and new energy solutions. The company specializes in electricity solutions, energy-efficient technologies, and power systems, including frequency inverters, servo motors, and power generation and transmission systems. Sikes is recognized for its innovation in power conditioning and power grids, and it collaborates with major enterprises like Siemens and Mitsubishi.

Product Offerings
Sikes offers a range of products including transformers, chokes (reactors), braking units, load banks, filters (harmonic, sine wave, EMC/EMI), power resistors, and energy regenerators. Their sine wave filters are designed for VSD systems to convert PWM output voltage to a near-sinusoidal voltage, suitable for 380V-480V networks, and can support motor cables up to 2,000 meters.

Technical Specifications
The sine wave filters feature a nominal operating voltage of 3×380 to 500VAC ±10%, motor frequency of 0-120Hz, and switching frequency of 2kHz -16kHz. They offer a high efficiency of 98-99% and are designed for continuous indoor operation with a protection degree of IP30 (IP40/IP54 on request).

Applications
These filters are applicable in industries such as metallurgy, coal, petrochemical, water treatment, and new energy. They are used in various applications including ventilators, conveyors, pumps, compressors, HVAC installations, elevators, cranes, wind power, UPS, and EPS systems.

Installation and Protection
The filters require a 230VAC independent power supply for cabinet cooling fans and feature over-temperature protection through dual temperature sensors. The system automatically restarts when the temperature decreases.

Selection and Recommendations
Selection of filters requires consideration of network conditions, rated values, service type, and presence of power factor equipment. The selection table provides detailed specifications for various filter models, including system voltage, motor drive rating, rated current, and insulation class.

Mechanical Data
Mechanical dimensions are provided for different filter types, with all measurements in millimeters.

Sine Wave Filter /Sinusfilter Block schematic / Blockschalt Sine wave filters for various servo motor of VSD systems(esp. for inverters or switching power suppliers), are designed to change the PWM output voltage of the inverter and generate an almost sinusoidal voltage. The passive series is intended for use in 380V-480V network. It enables a very high motor terminal voltage,since the voltage drop at the sinus filter is significantly below the markert standards.They could reduce the noise and to protect sensitive motors in industrial networks,and allow very long motor cables, up to 2,000 m....
