Switch Mode Power Supplies

Power supplies are important links in the energy supply chain of automation systems. Regulated switch mode power supplies are at the heart of every electrical cabinet. 24VDc has emerged as the standard control voltage for the supply of electrical sub-assemblies & systems. Power supplies have proven themselves reliable over many years in the supply of electrical & electronic systems. Of course they carry the CE mark & comply with all valid national & international standards.

They can be put to good use in an industrial environment, in process engineering & in the building sector. They also function reliably under harsh environmental conditions

SALIENT FEATURES OF WEIDMULLER PRO-M SERIES POWER SUPPLY :-

Best in Class by:

• Space saving installation in the cabinet by very small housing and by mountable without any gap (no clearance necessary).
• Robust and Powerful: Wide temperature range from -25°C…+70°C with additional power reserve at standard temperature
