Powerbox supplies the full Premium PSU range of power conversion products, with engineering support and access to custom and semi-custom solutions for railway, industrial and utility applications across Australia.

Designed and manufactured in Barcelona since 1981, Premium PSU is a market leader in railway and industrial power conversion, with over 900 custom designs in its portfolio and more than four decades of engineering experience behind every standard and bespoke product.

The range covers DC/DC converters, single and three-phase DC/AC inverters, battery chargers, IoT-enabled DC-UPS power supplies and AC/DC power supplies from 50W to 72kW, available in chassis mount, DIN rail and rack mount formats to suit rolling stock, control room and field installations. Off-the-shelf products are certified to EN50155 for rolling stock applications, and N+1 redundancy solutions are available for critical installations that cannot tolerate a single point of failure.

Where a standard product does not fit the application, the manufacturer's engineering team develops semi-custom and fully custom power conversion solutions, drawing on a portfolio of more than 900 completed designs to reduce development time and risk.

Powerbox provides local support across Australia for the Premium PSU range, helping engineers and integrators specify the right power conversion product or scope a custom solution for railway, industrial automation and power utility projects, including defence and security installations where demanding reliability and long service-life requirements apply.
