What this power supply does and where it fits
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.
Key ratings and what they mean for your installation
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. Operating temperature range is -25 to +55 °C, and storage/transport range is -40 to +85 °C. The free-convection cooling means you need to keep the mounting surface clear of obstructions — no stacking or boxing it in. The IP65 rating covers dust ingress and low-pressure water jets, so it's fine for food-and-bev washdown zones as long as the M12 connectors are properly torqued.
