E-T-A Circuit Breakers designs and manufactures a broad range of electro-mechanical and electronic components and sub-systems for circuit protection, control and instrumentation, including the world’s largest programme of circuit breakers for equipment (CBEs). Alongside examples of systems solutions, the company will be showcasing electronic circuit breakers for the protection of circuits in factory automation systems, as well as flow meters and level sensors for the process industry.  

The E-T-A ESS20 electronic circuit breaker selectively protects individual output circuits from switch-mode power supplies (SMPS). It provides advanced circuit protection for loads such as sensors, actuators, field bus couplers and controls. In combination with an E-T-A power distribution system, Module 17plus or SVS02, the ESS20 offers optimum utilisation of cabinet space, as well as minimising wiring and reducing installation and maintenance costs.

The company offers CBEs with current ratings from 50mA up to 500A. Activation mechanisms include thermal, thermal magnetic, magnetic and magnetic hydraulic. They include high performance products for aircraft, and specialised circuit protection devices for buses, trucks, workboats and pleasure boats. In addition to a wide range of standard products, many of which can themselves be adapted to specific requirements, E-T-A specialises in providing customised solutions. This is a complete service extending from design and prototyping through to full production of sub-systems such as 19" subracks, fully populated and pre-wired with plug-in CBEs. These solutions may be anything, from simple brackets and bus bars to more complex assemblies built and supplied ready to fit and forget. As circuit protection specialists, E-T-A has the expertise and in-depth knowledge of its products to ensure that the most suitable ones are chosen to optimise the design and produce the most cost-effective solution.

Sunon’s Power Motor 4028 Fan (40×40×28 mm) provides increased airflow, static pressure and high temperature endurance, making it the ideal thermal solution for the 1U-2U server market.

Increasingly powerful high-density information technology devices, like rack-mounted server and telecommunication boxes, have resulted in increased temperature outputs from the CPU, chips and RAM.  This has led to a notable increase in demand for more powerful cooling fans.

In the great majority of 1U-2U server applications, thermal management criteria are a major consideration when customers are making their choices.  In rack-mounted applications, the internal area of the box is often so dense that static pressure as well as airflow is a big concern.  A thermal solution must smoothly direct cooling air and powerfully overcome system resistance throughout the confined space.  Furthermore, the majority of servers operate 24 hours a day, generating high temperatures from their CPU, chipset, memory chip and power supply.  As a result, the amount and quality of the thermal cooling directly relate to the life expectancy of the server.  In conclusion, high airflow, high static pressure and long life expectancy are 3 essentials for a server fan.

The PMD 4028 is driven by an unique DC brushless motor that was developed, patented and manufactured by Sunon Research, the R&D engine behind Sunon Group. The series has benefited from the redesign of its electronic circuit, motor and impellers, which has increased the airflow and the static pressure of the new product by around 30%, in comparison with competitive products at 11,000 rpm. In addition, Sunon now launches the 13,000rpm version among competitors, which produces an amazing airflow of up to 23.5cfm at only 51.5 dB(A), temperature endurance at 700C supplied as standard, and a 900C version is also available for customers’ advanced criteria.

Product Features
Expected life:  50,000 hours
Rated Voltage:  12 Vdc
Speed/ Noise level/Air Flow:
13,000 rpm /  1.5 dB(A) / 23.5cfm
11,000 rpm / 45   dB(A) / 18.9cfm
 9,200 rpm / 40.5 dB(A) / 15.3cfm
Temperature Endurance: 700C as standard (900C optional)
Applications: Rack-mounted servers, telecommunication boxes, Industrial PC’s

The FireWire Buccaneer provides a high degree of environmental sealing for FireWire connections using standard IEEE 1394a interfaces with data rates to 400Mbs. Dust & waterproof to IP68 the connector system is ideally suited to industrial or hostile environments where a digital high data rate combined with a robust and secure connection is required.

Originally designed for office bound multimedia type equipment such as camcorders, computers, video cassette recorders and digital audio workstations it has found its way into scanners, web cams, external hard drives and external optical devices. But the ‘real-time’ ability for bi-directional, multi-speed data transfer on the same single network connection provides a truly universal connection for almost any consumer or commercial peripheral application.

This flexibility has now moved from the home into industrial environments where hazards of water and dust are present. The new FireWire Buccaneer connectors meets this challenge. The screw coupling thread ensures a vibration and shock resistant connection, while sealing caps maintain the IP68 rating of the connectors when not in use.

Cables are of over-moulded construction, available in 2m or 4m lengths as standard, they provide secure tamperproof connections between sealed and un-sealed 4 & 6 pole interfaces.

Chassis mounted connectors are terminated with adaptor leads for connection onto PCB’s.

Features include:

Dust & Waterproof to IP68
4 & 6 pole versions
Data rates up to 400Mbps
Cable configurations to 4m length
Panel connector has lead for PCB termination
Screw coupling for secure connection
Temperature range: 0degC to +70degC
Sealing caps to maintain IP68 rating
