Harmonic Filters

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 resource-saving systems, focusing on frequency inverters, servo motors, power generation, and transmission.

Product Offerings
Sikes offers a range of products including transformers, chokes (reactors), braking units, load banks, various filters (harmonic, sine wave, EMC/EMI), power resistors, and energy regenerators. Their passive harmonic filters are designed to reduce harmonic current distortion in power electronics with six-pulse rectifiers, suitable for non-linear three-phase power supplies.

Technical Specifications
The passive harmonic filters feature:

Nominal operating voltage: 3×380 to 500VAC ±10%
Operating frequency: 50Hz (60Hz on request)
THDi: <10% or <5%
Nominal power rating: 3.7kW to 630kW
Efficiency: 98 to 99%
Overload capability: 1.6x rated current for 1 min
Ambient temperature range: -25 to +40℃
Protection degree: IP30 (IP40/IP54 on request)

Applications
These filters are applicable in DC fast chargers, HVAC installations, fan and pump applications, industrial automation, robotic equipment, AC and DC motor drives, and equipment with front-end six-pulse rectifiers.

Technical Standards
The products comply with standards such as CEI EN 60831-1/2, IEC 831-1/2 for capacitors, and CEI EN 60439-1, IEC 439-1 for equipment. They are designed for continuous indoor operation.

Selection and Installation
Proper selection involves collecting network conditions, rated values, service type, and harmonic values. Installation requires attention to power supply and over-temperature protection, utilizing temperature sensors for fan control and filter disconnection when necessary.

Corporate Philosophy and Values
Sikes emphasizes support, professionalism, innovation, and integrity. The company aims to be a reliable partner, providing high-quality solutions for electromagnetic compatibility, power quality, and power magnetics, while actively contributing to international standards in power electronics.

Passive Harmonic Filter / Passive harmonische Filter Block schematic / Blockschalt ( THDi <10% ) Descriptions / Beschreibungen ■ Sikes passive harmonic filter is designed for almost any kind of power electronics with front-end -six pulse rectifiers. The filter can efficiently reduce the harmonic current distortion to required level. Typical applications:non-linear three-phase power supplies where potential risk is high due to thermal and electrical overload caused by harmonic currents. ■ Passive harmonische Filter ist für fast jede Art von Leistungselektronik mit Front-End--sechs Pulsgleichrichter...

■ Supply: to be made directly on line inductance or fuses supply. Three-phase + earth cable entry from the upper or bottom side for cabinet; The termination of a NC contact of max 5amps 250VAC for the remote indication of the running of the equipment are provided by means of a terminal board. ■ Over temperature protection: it is achieved by means of two temperature sensor. The first one has a lower activation threshold and controls the cooling fans located on the roof of the cabinet. The second one probe disconnects the filters when the temperature exceeds the maximum limit allowed. Restart from...
