Powerstax has added capabilities and customised solutions to its suite of transformer rectifier units. The move is supported by the technical expertise that the company has gained following the acquisition of Drake Power in July 2012, as well as the additional engineering resources that Powerstax has since developed. The company says it is now offering a comprehensive product platform for performance-enhanced power systems.

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

Thanks to their rugged construction, the Powerstax transformer rectifiers are 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. High mean time between failure (MTBF) figures prolong operational lifespan to avoid costly maintenance call outs. Heat dissipation challenges are handled by using fan, water, or oil-based mechanisms (or a mixture of these).

Among the many industrial tasks for which the power sources may be employed are electro-chlorination, electroplating, impressed-current cathodic protection, electrophoretic paint deposition, electrocoagulation and various other electrochemical processes. Anything from 1 to 18 outputs can be specified, with a choice of fixed or regulated output options. Compliant with the BS EN 60146 standard, these power solutions support an operational temperature range from -25℃ to +55℃.
