CUI’s Second Generation of Digital Point-of-Load Modules Dynamically Set Optimum Stability in Real Time as Conditions Change

CUI Inc announced the release of its second generation digital point of load dc-dc modules for distributed power architecture applications. The NDM2P series is the latest addition to CUI’s Novum® Advanced Power product line, which focuses solely on the design and development of leading edge power platforms. The modules offer true cycle-by-cycle compensation, autonomously balancing the trade-offs between dynamic performance and system stability. With this feature, designers are able to bypass the traditional practice of building-in margins to account for factors such as component ageing, manufacturing variations, and temperature, which inevitably lead to higher component cost and longer design cycles. With the NDM2P’s self compensation feature, the module is able to dynamically set optimum stability in real time as conditions change. With the addition of these second generation modules based on Powervation’s digital IC, CUI continues to be the only module manufacturer in the industry to offer a full portfolio of self compensating digital POL modules.

Offering efficiencies above 93% at half load, the NDM2P series is initially available in three compact DIP configurations; a 12 A version measuring 0.825 (L) X 0.500 (W) X 0.286 (H) in., a 25 A version measuring 1.01 x 0.54 x 0.32 in., and a 50 A version measuring 1.215 x 0.79 x 0.36 in. SMT and SIP versions will be available as well. Additionally, to support dual layout needs, the modules are footprint nested.

The NDM2P series is available with an input range of 4.5~14 Vdc and a programmable output range of 0.6~3.3 Vdc. Features include active current sharing, voltage sequencing, voltage tracking, synchronization and phase spreading, programmable soft start and stop, as well as a host of monitoring capabilities. All features are dynamically programmable via PMBus commands or a simple, easy to use GUI.

“This is our second generation of fully-featured digital modules based on the Powervation technology,” said Mark Adams, CUI’s Senior Vice President. "The NDM2P is our highest performance family to date, targeting customers that value high efficiency and fast transient response in an extremely compact module design."

Engineering samples are available immediately for select customers.

Biasi Develops ActivA Unique Boiler Range Biasi UK has developed ActivA, a new range of high efficiency A rated condensing boilers boasting a unique heat exchanger. The launch of ActivA is further testimony to the company's commitment to strengthen its position in the UK domestic gas boiler market. At the heart of ActivA is a newly developed pre-mix condensing heat exchanger that is manufactured in a corrosion resistant, pressure moulded aluminium. Its sectional construction means it can be easily adjusted for different boiler outputs and its 'multipass' design ensures very low resistance for both combustion and water passage. This unique heat exchanger carries a five year guarantee. Designed to provide outstanding heating performance at an affordable price for almost all types of domestic properties, the compact range boasts some of the smallest boilers available - at just 700mm high x 400 wide and only 290mm deep - thereby allowing installation in cupboards. As well a

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as

SMOKE SPILL INDUCTION MOTORS

STANDARDS AS 1668, AS 1359, BS 7349, BS 4999, BS 5000, IEC 34, IEC 72. GENERAL Western Electric Smoke Spill motors are designed to meet the requirements of Bitish and Australian Standards. AS 1668. 1 states that the objectives of Smoke Control are:         a) to vent smoke from the fir-affected compartment: and         b) to reduce the spread of smoke to fire isolated exits and other compartments.   In general Smoke Spimm motors are required to continue to operate driving extraction fans in a building, in the case of a fire. Usually these motors operate air circulation fans as part of the normal operation of the building, however if a fire occurs they must continue to operate for a period of time to extract smoke and\or dangerous fumes from the building and allow rescue services some assistance in rescuing any occupants still in the building. it is expected that hte fumes being extracted will be at high temperatures, well above normal ambients
