Product Description

Siemens SITOP PSU8200 power supply identified by MPN 6EP3437-8SB00-0AY0, a three phase primary switched mode unit built for stable 24V DC bus distribution in automation panels, PLC enclosures, and control cabinets. The nameplate confirms a three phase AC input rated 400 to 500V at 50 to 60Hz and a regulated 24V DC output at 40A, giving a maximum output of roughly 960W. The unit mounts on standard DIN rail and carries a TESTED mark along with UL, CE, EAC, and DNV GL certification markings on the label.

Serial number YSU/R5A93HBTA is printed on the nameplate along with the manufacturing origin, Siemens AG Osterreich, made in Romania. This listing is offered as Surplus Untested inventory, so functional testing has not been performed on this specific unit and no manufacturer warranty applies. Buyers matching this exact catalog number for spare inventory, panel replacement, or maintenance sourcing can use the confirmed MPN and nameplate ratings above to verify fit against their existing SITOP PSU8200 installation.
