The SITOP PSU100C 6EP1332-5BA20 is Siemens' NEC Class 2 compliant compact DIN rail power supply, delivering 89W at 3.7A for applications requiring power-limited outputs in hazardous locations and marine environments.

Core Function

With automatic 85-264VAC wide-range input and a fixed 24VDC output, this supply meets NEC Class 2 power-limiting requirements per UL 1310, simplifying compliance in North American installations. ATEX (II 3G Ex nA IIC T4) and marine certifications (ABS, DNV GL) extend its use to hazardous areas and shipboard systems.

Technical Specifications

Operating at 87% efficiency, the unit features electronic short-circuit protection with automatic restart and overvoltage protection. Low no-load losses (0.75W max) suit applications with frequent standby cycles. A green LED indicates output status.

Installation

The 52.5mm-wide plastic housing mounts on 35mm DIN rails. Plug-in screw terminals enable pre-wired installation. Fifty millimeters of top/bottom clearance is required for convection cooling.
