TDK mejora sus filtros EMC LeaXield. Minimización de corrientes de fuga a tierra hasta 1 A

/0 Comentarios/en , /por

TDK Corporation (TSE: 6762) anuncia que ha rediseñado y mejorado el filtro de corriente de fuga activa Leaxield ™ de EPCOS, una solución única que es capaz de minimizar las corrientes de fuga a tierra en sistemas de variadores basados en convertidores. LeaXield está diseñado para aplicaciones en unidades de velocidad variable como las de máquinas herramienta, bombas, compresores, sistemas de transporte y otros dispositivos conectables. En estos sistemas, las corrientes de fuga a tierra agregadas pueden hacer que los RCD (dispositivos de corriente residual) se disparen en su umbral. Como resultado, los RCD no son utilizables.

LeaXield está disponible para corrientes de carga de hasta 50 A a una frecuencia nominal de 50/60 Hz y voltajes de fase a fase de hasta 520 V AC. El filtro de corriente de fuga activa se conecta entre el RCD y el filtro de entrada EMC del convertidor en las redes de energía trifásica TN trifásica y no requiere una fuente de alimentación adicional. LeaXield puede utilizarse para corrientes de fuga a tierra de hasta 1 A y puede compensar efectivamente las corrientes de fuga en un amplio rango espectral de 150 Hz a aproximadamente 30 kHz.

LeaXield acopla una corriente de desplazamiento de fase de 180° con una amplitud idéntica a la corriente de fuga de las fases respectivas y la devuelve a la fuente. Esto evita que las corrientes de fuga fluyan a través del RCD y se disparen involuntariamente, lo que aumenta la disponibilidad de la planta.

Gracias a su diseño compacto, LeaXield también es adecuado para la modernización de instalaciones existentes. Como no se requiere una fuente de alimentación externa y el gasto de instalación es mínimo.

Principales aplicaciones:

  • Drivers de velocidad variable basados en convertidor
  • Dispositivos enchufables

 

Principales características y beneficios:

  • Minimización de corrientes de fuga a tierra hasta 1 A.
  • Alta compensación de corriente de fuga en el rango de frecuencia de 150 Hz a 30 kHz
  • Diseño compacto
  • Mínimo gasto de instalación, no se requiere fuente de alimentación externa

TE: BUCHANAN WireMate ITB Modular Poke-in Connectors

/0 Comentarios/en , , , /por

BUCHANAN WIREMATE ITB RELEASABLE POKE-IN CONNECTOR

• Fast and easy termination with reliable poke-in technology (no wire crimping)

• Reduced profile for good lighting effect via ITB application

 

Inverted Thru-Board(ITB) connectors join the BUCHANAN WireMate family from TE Connectivity (TE), specially designed for use in linear and circular LED modules found in all sorts of commercial and industrial lighting systems. The unique headers enable power delivery from the underside of the PCB and LED arrays, eliminating top-surface wire management issues. With their easy-to-use poke-in and wire release features, the new connectors help shorten installation time and provide extra flexibility for reuse and wire replacement. The reduced profile of the connector takes only 2mm in height above the PCB top surface while horizontal wire insertion minimizes space usage beneath the PCB. The connectors are modular in design, available for up to five wire connections and in different colors to help installers avoid mistakes when inserting wires. The connectors conform to the UL 1977 standard for component connectors for use in data, signal, control and power applications.

 

FEATURES

• ITB Wire to Board Connection with Horizontal Wire Insertion

• Wire poke-in design with strong wire retention

• Wire release feature for wire replacement

• Applicable for SMT soldering process

• Applicable wire size: 18-22AWG

• Modular housing design for multi-color combinations

 

KEY BENEFITS

• Reliable poke-in technology (no wire crimping) for fast and easy termination

• ITB application reduces profile for good lighting affect

• Wire release feature enables easy re-work and robust design of release mechanism helps prevent damage during wire assembly and rework • Space saving low profile design

• Lower inventory and production costs with higher connection variations supported by a side by side

 

APPLICATIONS

• Commercial Lighting

• Office Lighting

• Industrial Lighting
