Luso Electronics Distribution today announced availability of a series of highly compact AC-DC switching power supplies that deliver up to 260W of power and eliminate the fans and fan controllers required to cool conventional power supplies, thereby saving cost and freeing up valuable component space. Removing fans and related components and circuitry is also a significant advantage in increasing MTBF and reducing noise in end products.

Manufactured by N2Power, the 260W power supply is essentially the ‘Convection Cooling Option’ from the company’s XL375 series of highly compact AC-DC switching power supplies, which is suitable for a myriad of applications including as industrial automation, telecommunications, gaming systems, security and surveillance systems, and network servers.

The Convection Cooling Option power delivers 260W across all output voltages –eight models are available in the family featuring output voltages from 12V to 56V. “These power supplies deliver high flexibility in power system design,” said David Zelkha, managing director of Luso Electronics. “Engineering teams can design in both convection- and fan-cooled power supplies that use the same very compact and low-profile 3.3 x 5 x 1.5in packaging, connectors and layout, saving both time and cost.” The power supply’s very low profile packaging means it is also ideally suited to 1U product designs.

All models in the series offer Active Current Sharing to allow up to four supplies to be operated in parallel for high-output applications. The Active OR-ing Mosfet Board option is available for N+1 applications. Both 5V standby and 12V auxiliary outputs can be wired OR-able when the main output is disabled. In addition, synchronous rectification delivers exceptionally high efficiency of up to 93% in some models.

N2Power supplies meet a full range of international agency requirements, including RoHS, UL, DEMKO, CE Mark and FCC Class B.

Avnet Abacus, one of Europe’s leading interconnect, passive, electromechanical and power distributors, has announced that it will make its debut at Embedded World in 2012, demonstrating embedded power solutions for diverse applications as Smart metering, LED lighting, energy harvesting, Information systems, digital imaging and wireless LAN systems. The company will also have CAN-bus interface and sensor products on display for the first time.

The emerging markets mentioned above require much more than single component approach. In solid state lighting, for example, it is important to support the LEDs with the latest, high reliability driver IC circuitry, passives and connectors in order to maximize the benefits of moving away from older, inefficient filament & fluorescent technology. Applications for energy harvesting, are so new that many approaches are currently under evaluation and designers need to see a complete systems picture before deciding on which technology is most appropriate.

Comments Alan Jermyn, VP European Marketing at Avnet Abacus: “We have paired exciting new, enabling technology from companies such as Cymbet and Enpirion with passive and electromechanical products from the industry’s leading names to ensure that designers looking to develop energy- and cost-efficient embedded systems can access a full package of parts designed to work perfectly together. Embedded World 2012 is the perfect opportunity for us to showcase our technical and applications capabilities, and we will also take the opportunity to feature products only recently launched.”

Photon Power Technology has extended it range of Fanless Power Supplies from the highly respected Taiwanese manufacturer, Magic Power. New models include the 400W MPI-U400 series and the 220W MPI-822H 1U ATX Power Supply. Using thermal management techniques gained over many years, Magic Power now offers an extremely comprehensive range of Fanless ATX and single output power supplies in 1U format ranging from 60W to 300W.

All models are fully compliant and feature high efficiency fanless design for higher system reliability and lower noise. Based around a thermally efficient U-channel measuring only 198x98x41, the MPI-U400 series features an active PFC to meet IEC61000-2 /3-3. Other features include remote voltage sense, adjustable output (+/-10%) and universal input. A UPS charger module is also available for systems where battery backup is required. The MPI-400U series is available in 12V or 24V versions and will provide 400W continuously at temperatures up to 50°C and will operate at full power up to 70°C with additional fan cooling.

The MPI-822H builds on Magic Power’s impressive array of 1U Fanless ATX/ITX Power Supplies and offers full ATX compatibility. To keep up with the latest industry demands, the MPI-822H consumes less that 0.5W when on standby. Again using a thermally efficient U Channel design, the MPI-822H will operate up to 170W convection cooled and 200W with fan cooling. The active PFC ensures continuous operation from 96V to 264VAC supplies and meets EN61000-3 for line harmonics and EN 55022 class B for EMI. The MPI-822H joins an extensive range of Fanless ATX power supplies for both industrial and medical applications ranging from 60 Watts to 300 Watts with both AC and DC input versions available.

Photon Power Technology Ltd is the authorised UK distributor for Magic Power Technology Co Ltd and as such is able to assist with any “design in” projects for both standard and custom power supply requirements.

Recognising the growing need for innovative, easy and high efficiency power solutions in the latest equipment designs, Farnell has announced the signing of exclusive agreements with industry-leading manufacturers Linear Technology and Wuerth Elektronik to stock new power conversion products and evaluation kits.

Farnell will offer Linear Technology’s LT3573, 74,75 and LT3748 isolated monolithic flyback switching regulators that significantly simplify the design of a flyback converter as they do not require a third winding or optoisolator and can sense the output voltage directly from the primary side flyback waveform.  The regulators are suitable for use in a wide range of applications in the industrial, medical, communications, and lighting markets.

The introduction of more than 50 new, off-the-shelf flyback transformers with several different output voltages from Wuerth Elektronik complements the existing range of over 2400 products that Farnell already offers from the German headquartered manufacturer. The speed and ease with which new designs can be developed using the new Wuerth transformers is aided by the availability of 2.5W, 7W, 10W, 12W an d 30W evaluation kits that Farnell will also stock to support its customers.
