PROmax - switched-mode power supply

Powerful power supply for machines and systems
PROmax offers diverse solutions for demanding automation
Let's connect.


Power supplies for large systems and machines are particularly challenging. Failures caused by device defects impact on the entire production line and can result in high costs.


Our powerful and durable PROmax switched-mode power supply units are

designed for particularly demanding requirements. Continuous overload of up to 20 % or transient peak loads of 300 % are easily handled by PROmax.


High boost capability and full power are also made possible over a wide temperature range. Our switched-mode power supply units can be used around the world and are also suitable for confined spaces thanks to their low width.

Intensive torque loads at high cabinet temperatures place special demands on the power supply for large machines. Our PROmax delivers the power needed for overloads, even at high temperatures.

Product advantage


High boost capability for all industrial systems

Whether in large machines, power or process systems, thanks to their high boost capability, space-saving housing geometries, wide temperature range and comprehensive approvals, our PROmax switched-mode power supply units are suited for universal use anywhere in the world.

Space-saving width

Thanks to a very small width and direct side-by-side fitting, minimal space is required on the DIN rail.


Continuous output powers of up to 120 % at temperatures up to +45 °C and high output peaks up to 300 % ensure safe operation even at the limits of the performance range.

Robust and reliable supply

MTBF values of more than 500,000 hours and a wide temperature range of -25 °C to 70 °C ensure reliable system supply. Start-up temperatures of -40 °C make the PROmax particularly robust.
