Sine wave Filters

Product catalog summary

Company Overview
Sikes Electric Co., Ltd. is a leading provider of electrification, automation, and new energy solutions. The company specializes in energy-efficient and resource-saving technologies, offering systems for frequency inverters, servo motors, power generation, and transmission. Sikes is recognized for its advanced solutions in electromagnetic compatibility, power quality, and power magnetics.

Product Offerings
Sikes designs and produces a range of products including transformers, chokes (reactors), braking units, load banks, harmonic filters, sine wave filters, EMC/EMI filters, power resistors, and energy regenerators. The company is known for its innovation in power conditioning and power grids.

Sine Wave Filters
Sikes' sine wave filters are designed for various servo motors in VSD systems, particularly for inverters or switching power suppliers. These filters convert PWM output voltage to a near-sinusoidal voltage, suitable for 380V-480V networks. They reduce noise, protect sensitive motors, and support long motor cables up to 2,000 meters. Applications include metallurgy, coal, petrochemical, water treatment, and new energy sectors.

Technical Specifications
- Nominal operating voltage: 3×380 to 500VAC ±10%
- Motor frequency: 0-120Hz
- Switching frequency: 2kHz -16kHz
- Residual ripple voltage: THDv <5%
- Efficiency: 98 to 99% at nominal voltage and power
- Overload capability: 150% for 60s, 120% for 60min
- Protection degree: IP30 (IP40/IP54 on request)

Selection and Installation
Selection of sine wave filters requires consideration of network conditions, rated values of loads, and the presence of power factor equipment. Installation involves ensuring proper power supply and over-temperature protection using temperature sensors.

Mechanical Data
Dimensions and weight vary by model, with specific details provided for each filter type. The filters are designed for easy installation and commissioning, optimized for long motor cables and full-load operation.

Partnerships
Sikes collaborates with renowned enterprises such as Siemens, Mitsubishi, Yaskawa, Hitachi, Fuji, Thyssen, and Emerson, leveraging technological advantages and long-term experience.

Descriptions / Beschreibungen ■ Sikes Sine wave filters for various servo motor of VSD systems(esp. for inverters or switching power suppliers), ai designed to change the PWM output voltage of the inverter ar are igned 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...
