December 14 | Company News | Press Officer
Powerstax features in the Daily Telegraph’s just published list of 1000 of Britain’s Brightest Businesses. According to the newspaper “The list is a celebration of the 1,000 mid-sized companies which have weathered the economic storm and are set to be the foundation of the UK’s recovery”.
The list identifies 1,000 Private and Alternative Investment Market-listed companies, from farming to IT firms; restaurants and retailers; to construction groups and professional services. The snapshot focuses on companies and partnerships with sales of between £5m and £500m. Many are growing quickly, others are doing so more slowly, often sustained over many years. It means young gazelles sit alongside long-established companies that have found new ways to grow.
The research was compiled with the help of NESTA, the innovation agency, which identified fast growing companies, and business information specialist Dun & Bradstreet (D&B), which verified the information. To read the full article go to Telegraph-1000-Britains-Brightest-Businesses
Tim Worley, CEO of Powerstax comments; “We are proud to have been included in the Daily Telegraph’s list. It’s rewarding to have our investments in UK design and international sales come to the attention of NESTA and the mainstream media. There is no doubt the market is very tough and our success is down to a great deal of hard work, really understanding our customer’s needs and working in close partnership with them to deliver high-efficiency power conversion systems on budget and on time.”

260 watts in 1U without fans for OEM solutions
Increased reliability – reduced noise

(pdf format 458k)
Powerstax, one of Europe’s leading value-added power solutions manufacturers, announces the availability of a convection cooled option for its N-03751-PFC Series of ultra-compact AC-DC switching power supplies. The N-03751-PFC Series is designed for outdoor and semi-sealed industrial applications and low noise office environments and its low profile will suit 1U rack mounted systems.
The new convection cooled option delivers 260 watts of output power across all output voltages and eliminates the fans and fan controllers required to cool conventional power supplies. The convection cooled option reduces costs and frees-up valuable system real-estate. As the Powerstax N-03751-PFC does not require forced air for full 260W operation, the system designer no longer has to be concerned with channelling air over the PSU, simplifying thermal design. Removing the fans also significantly increases system reliability and reduces audible noise of end products, making them ideal for office environments.
Where an end system may be used in different environments, customers can simplify system level design by specifying the convection cooled Powerstax N-03751-PFC and if required substituting the forced-air cooled version which offers the same very compact, low profile 5×7.7×2.3mm (3.3x5x1.5”), packaging, connectors and layout, saving design time and costs.
“Powerstax power supplies are inherently reliable.” Says Tim Worley, CEO of Powerstax plc. “Since the reliability of a power supply is in many cases degraded by the reliability of its cooling fan, the introduction of this range of compact convection cooled power supplies offers our customers a very real increase in reliability with added packaging and cost benefits. Convection cooled power supplies reduce overall system power consumption and cooling requirements and are not susceptible to failures due to dust clogging fans or airborne contamination of their circuit boards.”
The synchronous rectification technique of the Powerstax N-03751-PFC Series delivers exceptionally high efficiency, up to 93% in some models and all models feature active current sharing allowing up to four power supplies to be operated in parallel for high output power applications. An optional active OR-ing mosfet board is also available for N+1 redundant applications. Both 5V standby and 12V auxiliary outputs can be wired OR-able when the main output is disabled.
The Powerstax N-03751-PFC Series has a very compact footprint of 3.3” x 5.0” (83.8mm x 127.0mm) and low profile of 1.5” (38.1mm) suitable for use in 1U racks, an active PFC input over the range 90–264 VAC, an operating temperature range of –25ºC to +50ºC and meets a full range of international agency requirements, including RoHS, UL, DEMKO, CE Mark and FCC Class B. Output is protected against overvoltage, overpower, short circuit and over temperature.
September 2011 Extensive Range of MIL Spec Power Modules available from Powerstax
Comments Off
MIL COTS converters for vehicle and mobile applications.
View complete range at DSEi 13th-16th September, London ExCel Stand N9-349.
Powerstax, one of Europe’s leading application-rich power solutions specialists, announces the availability of its PX range of competitively priced, high reliability MIL standard DC:DC converters and pre-regulator, filter and hold-up modules.
Tim Worley, CEO of Powerstax comments; “Our PX range of power modules offers designers one stop shop for complete board level power solutions.”
The Powerstax PX range of DC:DC converters contains more than 40 products including single, dual and triple output versions with output power up to 30W. All models have an ultra-wide DC input range of 16-40V and output voltages which may be selected as combinations of 5V, ± 12V, ± 15VDC. The converters employ fixed high-frequency (400kHz) switching technology with an on-board input EMC filter and built-in soft start circuit. All modules have output short circuit and overload protection.
The Powerstax PX series pre-regulator module operates up to 50W and can extend a DC-DC converter’s input voltage range while inhibiting supply rail surges and spikes. The pre-regulator offers three operating modes: Normal mode operation occurs between 16V to 40V input voltage when the module is operating in a steady transparency state. Voltage mode is deployed when the bus voltage falls below 16V putting the voltage regulator module into BOOST mode and raising its output voltage to 20V. Should the input voltage drop below 10V the voltage regulator module will safely shut down. And finally surge and spike suppression mode may be used when the input voltage goes above 39V. The pre-regulator module output voltage is then clamped at 38.5VDC and can withstand the maximum 80V/50ms bus voltage surges and up to 600V/20?s spikes.
The Powerstax PX series switching regulator modules provide an extended input voltage range to allow extra low voltage outputs from the output of one of the PX series DC:DC converters. Input voltage range is 4.5 – 32VDC with outputs of 2.5, 3.3 or 5VDC as standard.
Providing a hold time 10?s/?F the Powerstax PX series hold-up module provides an alternative solution to reduce the amount of capacitance needed by charging the hold up
capacitor at high voltage (typical 38VDC) while limiting the input current. This provides enough time to facilitate an orderly system shut-down in the event of a brown-out or complete power failure.
The final modules in the PX series are two EMC filter modules which meet the requirements of MIL-STD-461D, CE102 levels of conducted power line noise.
All PX series modules have an operating temperature range from -55 to +105 ºC, employ proven SMT technology offering high reliability, low noise and high power density
Typical applications for the Powerstax PX series include Mil and aviation systems and high reliability industrial applications. Powerstax provides standard and custom power solutions for defence, homeland security, shipboard and ground systems and mobile/vehicle mounted wireless and radar systems, telecomm infrastructure and security systems.
