The SITOP PSU3400 6EP3134-0TA00-0AY0 is Siemens' high-power 24VDC-to-24VDC DIN rail stabilizer, delivering 260W at 10A for large automation loads in battery-buffered and marine DC systems.

Core Function

Accepting 14-32VDC input, this galvanically isolated converter provides a tightly regulated 24VDC output adjustable up to 28VDC. It ensures stable power to large PLC racks, multiple I/O stations, and drive controllers even as source voltage fluctuates. The wide input range accommodates battery discharge curves in 24V UPS-backed systems.

Technical Specifications

At 93% efficiency, the 42mm-wide unit dissipates approximately 20W at full load with natural convection cooling. Electronic protection covers short-circuit, overload, and reverse polarity. ABS and DNV marine certifications qualify the unit for shipboard automation.

Installation

Snap-on 35mm DIN rail mounting. Screw terminals with dual output connections for load distribution. A signaling relay provides remote monitoring. Up to two units operate in parallel for 520W capacity.
