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.

Expected life:  50,000 hours
Rated Voltage:  12 Vdc
Speed/ Noise level/Air Flow:
13,000 rpm /  1.5 dB(A) / 23.5cfm

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

Arcolectric has some 40 years experience in the design and manufacture of neon and filament indicators. Now, with mains rated LED’s becoming more commercially viable, the opportunity is here for this expansive range to use a technology that is inherently more reliable.

These new mains LED versions offer flicker free illumination and are adaptable enough to operate from 230Vac to 110Vac. The standard colour options include red, yellow, green, blue and white. It's often been difficult to achieve pure white or blue colours with neon or filament lamps in the past but these LED's will provide a bright,
clean light.

The extensive range includes a great many options; snap and screw fixing to panel, mounting hole diameters from 5.8 to 14.0mm, bezels sizes from 6.7 to 18.3mm diameter, round and square lens shapes, protruding and low profiles, chrome bezels and pre-wired or 2.8, 4.8 and 6.3mm terminals.

The ranges will carry internationally recognised approvals from Semko and UL laboratories.

Crydom the leading manufacturer of Solid State Relays (SSR’s) has launched a completely new range of microcontroller based devices. The MCTC is a self contained temperature controller in a single industry standard panel mount package.

The series combines all the necessary functions to accurately regulate temperature. With a simple set up procedure, they provide accurate control for designers for heater and cooling loads of up to 90A AC.

The MCTC requires a non-regulated low drive current DC source (10-32Vdc, 32mA max). The devices have an internally compensated thermocouple input, set to accept J or K types. Five available temperature ranges offering heating control over 37°C to 590°C and an inverse function for refrigeration down to –73°C. Setpoint adjustment is achieved by either low voltage dc or 4-20mA inputs. There is also separate enable/disable input to switch the load.

Integrated zerocross burst firing and proportional derivative control avoids setpoint overshoot. Operators can easily see the controller’s status with separate LED indication for setpoint condition and output status. Load voltage switching can be either 280Vac or 480Vac suitable for both single and three phase systems. Connections are simple screw connections both control and load side. The industry standard package makes it suitable for Crydom’s range of heatsinks.

           Single-Phase High Performance EMC Filters
Simplifies Panel Building and Industrial Control Systems

Schaffner Ltd the market leader in EMC components and systems announce the introduction of the FN 2412 series of DIN Rail mounting EMC Filters. This new family of high performance single-phase filters are will fit industry standard TS 35 DIN rails and offer a simple to use, time saving, cost effective solution to conducted EMC suppression for panel builders and control cabinet manufacturers. The extensive range of current and voltage ranges available mean that even special applications can now be protected with an off the shelf solution.

A sophisticated mounting system provides a simple and time saving snap-in mounting of the filters onto TS 35 DIN rails. The innovative shaping of the DIN-rail mounting bracket as well as its material guarantee low-impedance connection to the HF ground ensuring an optimal (asymmetric) filter effect, which has previously only been available by using traditional bolt-down chassis mounting methods. The FN 2412 filters have been designed, electrically and mechanically, to meet the requirements of industrial equipment and control cabinets.

With models available off the shelf for rated currents from 8 to 45 A the correct FN 2412 EMC filter will typically ensure system conformity to Class A limits for Industrial and Residential environments. Owing to the high saturation resistance, this high attenuation performance is available even with very aggressive noise sources and under full load. Schaffner’s specially designed “Touch-Safe” connection terminals make accidental touching of live conductors impossible ensuring maximum safety when in use.
 
These new filters are designed for a maximum continuous operating voltage of 250 VAC and there is also a standard version FN 2412H available for higher operating voltages up to 520 VAC. All models are safety agency approved to UL, CSA and ENEC and are RoHS compliant.

Andrew Kotas, Marketing Manager of Schaffner Ltd. comments “these are our first Din Rail mounted EMC filters which we hope will provide our customers with even more convenience and flexibility when having to provide EMC suppression on their systems. While effective EMC protection is required to meet international noise emission standards it can also improve system reliability and reduce expensive downtime caused by external conducted interference damaging internal components”

The FN 2412 range of EMC filters are also available in chassis mounting form for applications where Din Rail mounting is not possible. Designated FN 2410 these noise suppression components are available for the same voltage ranges (250 VAC and 520 VAC) and for an extended current range up to 100 A.
