The SITOP PSU100D 6EP1322-1LD01 is Siemens' 100W ultra-flat DIN rail power supply, delivering 8.5A at 12VDC in a 30mm-high housing purpose-built for shallow control cabinets.

Core Function

Accepting wide-range 100-240VAC input (90-264V), this stabilized supply provides adjustable 10.8-13.2VDC output. It powers 12V automation equipment, LED lighting, small motors, and control circuits in installations where the 30mm height is the critical design constraint. The 87.5% efficiency minimizes heat buildup in confined spaces.

Technical Specifications

Electronic short-circuit and overload protection with automatic restart. The unit withstands 1.25× rated input overvoltage for 500ms. With an MTBF of 700,000 hours at 40C, it delivers long-term reliability. BIS certification (R-611003204) supports deployment in the Indian market.

Installation

Wall or DIN rail mounting in a 97×30×129mm footprint. Screw terminals accept 0.75-2mm wiring. The flat profile enables installation in distribution boards and compartmentalized enclosures where every millimeter of height counts.
