Voltis PRO taps into high performance VO market

Jul 9, 2014 | UPS & Standby Power

Marshall-Tufflex is reaping the rewards of its continued investment in the voltage optimisation market, as its Voltis PRO system has claimed a number of new installations.

Voltis PRO units (100A, 200A, 300A, 400A) feature automatic neutral-switching, bypass, intelligent control, visual display plus optional remote monitoring – but with the important addition of multi-tap transformers, allowing installers to select the most appropriate tapping on-site.

This high tech approach, combined with easy to install features (multi-tapping, smaller, lighter) have made it popular with specifiers working within the energy management sector. Installations have included aircraft hangers used for maintenance, shopping centres, offices and multi-occupancy accommodation.

Voltis PRO has three pre-programmed tapping settings (for mains at 245V or above, at 240V or at 235V), with the voltage being dropped by ten percent, eight percent and six percent respectively. For incoming mains of 240V and above savings of 10-20% are achievable, depending upon site demands and incoming power profile. Multi-tap transformers also offer customers greater in-use flexibility because tapping settings can be changed at any time if mains voltage levels change significantly.

“These units can optimise a wide range of incoming mains voltage levels,” said Jeremy Dodge, head of marketing and technical services. “The specification process is simple and installations are future proofed by allowing tapping settings to be changed as required. Our automatic bypass delivers peace of mind and improved efficiency. The optimiser will only work when it needs to (saving power on its own operation) and if the supply voltage exceeds acceptable parameters Voltis PRO protects power to site by switching to mains until supply returns to an acceptable level. Intelligent operation further enhances performance by automatically adjusting to supply/demand changes to maximise savings.”
