January 2014: Powerstax Strengthens its Transformer Rectifier Offering

Providing wide selection of options that facilitate creation of completely bespoke, high power solutions focused on specific application needs

Suit uncompromising environments Single or multiple outputs

Using proprietary transformer technology Advanced thermal management

8^th January 2014 – Powerstax, specialist provider of highly optimized power sources, has added further scope to the portfolio of transformer rectifier units it offers the market – with numerous value-added and full custom solutions available. Benefiting from the technical expertise it inherited following the acquisition of Drake Power, back in July 2012, as well as the additional engineering resources that Powerstax has since developed in this area, the company can now presents a comprehensive product platform through which performance-enhanced power systems can be defined.

Supporting conversion efficiencies reaching 96% and typical power factors of 0.85 (or as much as 0.99 if extensive power factor correction is applied), these units allow an AC input to be converted into a steady DC output – delivering power levels of up to 500kVA. They are available in either transductor-controlled, thyristor-controlled, or switch-mode configurations. With peak-to-peak output ripple kept to well within a 5% margin (or considerably lower if adequate DC smoothing components are incorporated), industry-leading voltage stability can be realized.

Thanks to their rugged construction, the Powerstax transformer rectifiers are highly suited to power system implementations in the most physically demanding of application settings, where they are exposed to severe weather conditions and extreme temperature fluctuations. Very high mean time between failure (MTBF) figures prolong operational lifespan and enable costly maintenance call outs to be avoided. Sophisticated cooling takes care of heat dissipation – using fan, water or oil-based mechanisms (or a mixture of these).
