The new A2000 series 19” rack mount configurable AC-DC power supply range provides multi output “custom” power solutions without the normal customisation costs and extended lead times.

Designed to deliver advanced market-leading versatility, the A2000 employs a modular construction using standard products from the Powerstax range. Over 46,000 possible output configurations, up to 12 isolated and adjustable outputs with total power up to 2,000W are available, enabling power supply designers to meet special and unique power architecture requirements with greatly reduced design time and costs.

In a convenient and compact 2U high 19“ rack mount package 350mm deep, the A2000 provides up to 2000 watts regulated single or multi-output dc supplies from a universal mains supply of 90-253Vac. It is possible to individually margin, enable, parallel or stack the outputs to provide literally millions of power solutions.

Additional features include zero load operation and fully floating outputs that have standard voltage ranges from 1.45V to 28V and include a 5V Bias supply at 50mA. Designed for EN61000-3-2 compliance and meeting Class B conducted emissions the A2000 series is ideal for the communications, industrial, instrumentation and test & measurement markets.

The innovative Powerstax design and topology allows rapid mainstream production turnaround of configured units, CE marked, in a matter of weeks. This enhanced flexibility together with lower design costs and improved lead times extends the appeal of rack mounted configurable power supplies for non-standard and custom applications.

The industry standard full brick size package 116.8 x 61 x 12.7mm (4.2 x 2.4 x 0.5 in) has a comprehensive range of innovative features and functions expected of Powerstax DC-DC converters. These include single wire connection, automatic current sharing parallel connectivity for true N+1 redundancy and high typical efficiency of 87% whilst an extended operating temperature range of -20ºC to +100ºC with no derating above 85ºC minimises power dissipation and helps simplify thermal management.

The versatility of the F351 is enhanced by a full range of in-built protection functions such as over-voltage, under-voltage and short circuit protection complemented by remote shutdown, thermal monitoring voltage and fixed frequency operation with external synchronisation features.

Fully isolated, with low input and output ripple, adjustable output voltage and designed to meet EN60950 and CE mark requirements, Powerstax also offers rapid design and development of non-standard and custom solutions from its own ISO9001 In-House facilities for applications not met by the standard range of F351 modules.

Available now, the F351 series provides flexibility, extra functionality and a scarce 12V input Step-Up dc-dc conversion that enables system designers to meet the rigorous demands of applications in Telecoms, Transportation, Industrial control and Distributed Power Architectures.

The Powersave is ideal for thyristor controlled rectifiers or transformer/rectifiers with motorised output control used in plating and electrophoretic painting processes.

It electronically maintains an average constant current density over a complete range of loads. Not only does this promote energy efficiency and help save costly electricity, but also means that it is easy to get the optimum results from a wide variance of work loads, whether the process is continuously changing on conveyor systems or if the component size and load density varies.

The Powersave helps speed production and improves versatility as once installed and calibrated, further adjustment should not be required provided the other parameters of the process remain reasonably constant.

By employing the “positive slope” principle of straight line relationship between current density and applied voltage the Powersave automatically predicts the slope of voltage increase or decrease which needs to be set to counter rise or fall in surface area and/or environment. With loading from 10% to 100%, accuracy of control of 5% for repeat identical work and 10% repeat accuracy on work with a different configuration can be achieved. This not only increases overall efficiency and precision in the process but helps reduce material waste and decreases time and costs due to possible re-work.

A very compact package, measuring 188 x 110 x 70mm, the standard Powersave units operate on 110V or 240V 50 Hz single phase supply with alternative electrical supplies available upon request.

The Powersave can be factory fitted to new rectifiers and power supplies or retro-fitted to existing equipment as part of the Preventive Maintenance Plans and On-site Service packages available via Powerstax plc.

Powerstax plc announces the introduction of the new ZTAH terminal adaptor providing a simple, quick and cost effective way to connect a standard pin half brick dc-dc converter without PCB mounting.

Supplying an option for screw and clamp connections to PCB pin type half brick modules, makes the ZTAH adaptor ideal for use during bench testing, design work and for industrial applications. Measuring 43mm x 55mm, the Powerstax ZTAH adaptor fits without difficulty within the industry standard half brick dc-dc converter footprint (61.0mm x 57.9mm).

At just 11.6mm high, the low profile ZTAH fits snugly on the top of the converters by either solder fit or alternatively, with a special pluggable option. The single sided adaptor does not hinder the conventional mounting of the converter module and permits units either to be cold wall mounted or employ an appropriate Powerstax heatsink fixed in the usual manner.

With maximum 24A output power rating, the two rows of 5mm pitch “Screw and Clamp” terminal blocks accommodate 1.5mm2 (26-16AWG) wire and provide an easy and repeatable way for system designers to carry out development and test functions whilst industrial field engineers can integrate, install and replace modules with just a screwdriver.

Available now, the simple design ensures a cost effective solution for those requiring a straightforward and re-useable interface for half brick DC-DC Converter with industry standard pin configurations.

Available in 2 industry standard sizes, the Powerstax MM range provides 1,000W, 600W and 400W power output, with 46,656 possible output configurations from up to 12 isolated outputs. The full user configurability of the MM series offers a flexible and cost effective solution to your exact medical power requirements.

Incorporating, universal input, Class B Conducted Emissions and 12mm Creepage, the MM range has Low leakage current of <300uA current with an optional Ultra Low leakage version of less than 150uA.

The modular design of the Powerstax MM series provides power outputs ranging from 1.45 to 28V that have individually controlled signals that offers literally millions of power solutions from the isolated and adjustable outputs.

The MM range has both series and parallel capability and can be stacked for up to 2000W output power. Zero load operation and Dual fused versions are also available.

Each Powerstax MM unit comes complete with 3 year warranty and are CE marked, EN60601-1, UL2601-1, IEC601-1 approved and fully compliant to EN61000-3-2.

Providing an unparalleled solution for system designers in a wide range of medical, laboratory and dental applications including drug infusion and chemical analysis equipment.

Effective from 19th May 2005, the change of name marks another milestone in the Company’s development after a period of rapid evolution and growth.

“The Powerstax plc name refreshes our branding and strengthens the Company's international identity with a name that is distinctive, memorable and relevant to a high-tech power conversion company” said Chief Executive Officer, Tim Worley. adding “We received a very positive reaction to the proposed name change from our customers, visitors to Electronica 2004 and from our EMEA and US sales channels. Keeping the same strong colour schemes and product branding has allowed us to demonstrate continuity and make the important point, that only the name has changed”.
