These highly efficient rectifiers offer a range of output voltages and power levels.

Easy to install and compact, these robust, reliable rectifiers are convection cooled and are available with temperature compensation, internal low voltage disconnect (LVD) and alarm card with relay outputs.

They can be used as standalone power sources or can be operated in parallel to provide redundancy or higher output ratings.

Choose from a range of internal options including load disconnect, current indicators, alarm and control interface and auto float/boost. Custom configurations can be specified and additional features can be added.

New Zealand made to guarantee design, manufacture and process integrity. Our robust proven conversion topology utilises only the highest specification components, ensuring unparalleled reliability benefits.
