The Siemens 6GT2898-0AA00 is a wide-range voltage supply built for the SIMATIC RF600 system, designed to power RFID readers directly. It takes a 1-phase AC input from 94 to 264 V (or DC from 120 to 353 V) and delivers a regulated 24 V DC output at up to 3 A, with a rated range of 0 to 4 A. The output is SELV/PELV isolated per EN 60950, so it's safe to run to readers in the field without extra isolation barriers. Efficiency is 90 %, and the unit relies on free convection for cooling — no fan, which means no moving parts to fail in dusty or washdown environments. The enclosure is IP65, so it's rated for hose-down and outdoor installation — you can mount it directly on a machine frame or near the reader, not just inside a cabinet. It fastens with four M5 screws, and the input comes pre-wired with a 2-meter Euro plug cable. The output side uses two M12 4-pin A-coded female connectors, which is the standard connection for SIMATIC RF600 readers. That means you can plug in two readers without additional junction boxes.
The 3 A output at 24 V DC is enough to power two typical SIMATIC RF600 readers simultaneously — the suitability note confirms it's designed for direct connection of two readers in Europe. The voltage tolerance is ±2 %, which keeps the reader supply stable even if the line voltage sags or surges within the 94-264 V AC window. Short-circuit protection uses a constant-current characteristic, so it doesn't latch off on a momentary overload; it just holds the current steady until the fault clears. That's important for a reader line — you don't want a power supply that needs a manual reset every time a cable gets pinched. The free-convection cooling means you need to keep the mounting surface clear of obstructions — no stacking or boxing it in.
