Schaefer Complete Product Range is available through Powerbox, backed by a partnership with the German manufacturer spanning more than 35 years. Schaefer designs and builds AC/DC power supplies, battery chargers, DC/DC converters, DC/AC inverters and AC/AC frequency converters from 100W to 7.5kW, with natural convection cooling available up to 2500W for installations where fan cooling is not practical or where reduced maintenance and quiet operation matter.

Several products in the Schaefer Complete Product Range hold type approval for signalling and level crossing applications, recognised by Sydney Trains, ARTC, Queensland Rail and Aurizon. That approval history makes the range a proven choice for rail operators managing compliance-critical power infrastructure, from trackside signalling cabinets to level crossing control systems. Beyond rail, the same engineering standards carry across mining, power utilities, renewable energy and defence applications, where reliable power conversion under demanding environmental conditions, vibration and wide temperature ranges is non-negotiable.

Powerbox provides Australian engineering support across the full Schaefer Complete Product Range, helping specify the right power supply, converter, charger or inverter for a given application and supporting projects from initial design through to commissioning and ongoing technical support. Whether the requirement is a compact DC/DC converter for a signalling enclosure or a higher-power AC/DC supply for an industrial site, the range covers the load.
