E-T-A, Electronic Circuit Breakers Provides Circuit Protection and Remote Switching for Telecom Systems

eta logo.jpg

E-T-A Circuit Breakers has introduced a new remotely controllable electronic circuit breaker for protecting and monitoring systems in the telecommunications industry. It can be used for the negative switching of loads on –48V DC power supply systems.  Major application areas include power distribution systems, exchange and transmission technology, and mobile telephone base stations.

 Y0306eta - E-T-A ESS60T.jpg

The new E-T-A ESS60T Electronic Circuit Breaker is available in a range of current ratings, from 5A up to 60A, to provide circuit protection and remote switching/resetting. Designed for installation in 19″ rack systems, it features an integral ON/OFF button, allowing manual reset, and an LED status indicator. The overcurrent protection capability reliably prevents destruction of electronic components or load lines during switch-on of capacitive loads or through an overload or short circuit. In the event of a short circuit, it is also designed to eliminate short-term high currents which could cause an undesired voltage dip in the power supply or in the power distribution system, thus avoiding consequent system crashes.

The ESS60T features an integral RS232 serial interface to allow re-programming of set overcurrent and undervoltage parameters to match changing circuit conditions. By this means the overcurrent threshold can be adjusted, and the undervoltage threshold can be adjusted between –36V DC and –48V DC to facilitate a priority-based load shedding capability in the event of failure of the mains power. The serial interface also enables ON/OFF switching from a remote location, as well as the ability to remotely reset the load circuit. The ESS60T meets the requirements of the European EMC directive.

E-T-A offers a wide range of power distribution systems, racks and circuit protection solutions for the telecommunications industry, as well as offering racks or sub-assemblies, wired and pre-fitted with circuit breakers, electronic power controllers and other components customised to meet specific requirements.

These products are highlighted in a new 20-page brochure ‘E-T-A Communication’, available free from E-T-A at http://www.e-t-a.com/uk_literature1.html. This covers products used in exchange and transmission technology as well as mobile telephone base stations. It emphasises the complete system solutions and explains the advantages of E-T-A circuit breakers, including their space saving, the ability to ‘hot swap’, and the local/remote re-set capability. Along with descriptions of 20 products it also lists their typical applications.

E-T-A, Modular Power Distribution Rail for Control Cabinets

 eta logo.jpg

Ideal unit for E-T-A 8345 hot-swappable CBEs in telecomms and other industrial applications

E-T-A Circuit Breakers has introduced a new, compact, modular power distribution system suitable for rack mounting to handle currents up to 125A per channel. When populated with E-T-A circuit breakers, it facilitates rapid start-up and re-configuration of complex systems without downtime.

 Y0407eta - X8345_D01.jpg

The E-T-A X8345-D01 Power Distribution System is a 2U-height rail system designed for fitting into 19″/23″ or ETSI racks. Its modular design allows customer-specific and economic configurations in telecommunications and transport industries, for power supplies, switchgear, instrumentation and process control applications. It accepts the plug-in E-T-A type 8345 circuit breakers which can be specified to handle from 0.05A up to 125A each and which offer group signalisation. A complete X8345-D01 module will handle 600A in total. Systems can be extended or re-configured without powering down as X8345 circuit breakers are hot-swappable. Live parts in the plug-in area of the load terminals are protected against brush contact to IP20. 

In combination with the toggle switch, hydraulic-magnetic type X8345 circuit breakers, the X8345-D01 rack is ideal for telecommunications control cabinets. They provide a comprehensive power distribution system to protect wireless or wireline equipment, whether for switching technology, transfer mode systems, network access technology or mobile radio systems.

The E-T-A 8345 magnetic circuit breaker for equipment (CBE) is a fully approved circuit breaker for telecommunications equipment, plant control systems, the rail industry and other applications where reliable protection in a compact package is essential. The 125A maximum rating is 25A higher than the industry norm, allowing designers to increase power output without consuming valuable rack space. The product is fully approved to UL489, UL1077 and EN 60934, requiring the circuit breaker to be fit for purpose after interrupting a short circuit at its maximum specified fault rating. Thus, an extra measure of protection for expensive electrical equipment is assured, reducing costly downtime caused by power interruption.

E-T-A offers a wide range of power distribution systems, racks and circuit protection solutions for the telecommunications industry, as well as offering racks or sub-assemblies, wired and pre-fitted with circuit breakers, electronic power controllers and other components customised to meet specific requirements.

These products are highlighted in a new 20-page brochure ‘E-T-A Communication’, available free from E-T-A at http://www.e-t-a.com/uk_literature1.html.  This covers products used in exchange and transmission technology as well as mobile telephone base stations. It emphasises the complete system solutions and explains the advantages of E-T-A circuit breakers, including their space saving, the ability to ‘hot swap’, and the local/remote re-set capability.

E-T-A, Compact, Electronic, Non-Contact, Level Sensor and Monitor

 eta logo.jpg 

High Reliability even with Aggressive Media

E-T-A Circuit Breakers has introduced a new, tube sensor for non-contact, long-life detection and signalling of MIN or MAX liquid levels. Easily snap-fitted to a tube, the TLS100 features solid state circuitry to provide extremely precise and reliable operation for complex or sophisticated applications in process industries such as food, chemicals and pharmaceuticals as well as with medical equipment.

 Y1114 - E-T-A TLS 100.jpg

The compact E-T-A TLS100 Tube Sensor is a non-contact, capacitive sensor providing reliable limit-value monitoring over a long life span. It is designed to easily clip onto a tube or pipe, enabling monitoring of water and similar low viscosity liquids, aggressive or not. Two mounting lugs also enable additional local fixing for security. The tubes can be of plastic or glass with up to a 4mm wall thickness. Clips can be specified for tube diameters of 10mm, 15mm or 25mm. Even containers with difficult designs can be monitored by means of a simple by-pass tube.

The TLS100 has a micro-controller at its core to control key functions such as switch point, MIN or MAX monitoring and response delay. Adjustment is via a 15-step potentiometer on the body of the sensor. The solid state circuitry ensures extremely precise, reliable operation with minimal maintenance, thanks to the absence of moving parts. Running from a 12V DC or 24V DC supply, it offers a short-circuit and overload-proof plus or minus switching output signal of up to 1A. The supply and signalling lead is optionally built-in or plugged in.
