The Siemens 6GT2898-0AC20 is a SIMATIC RF600 wide-range power supply that takes 100 to 240 V AC single-phase input and delivers a regulated 24 V DC output at 3 A. It's built for the RF600 reader family, with two M12 4-pin, A-coded female output connectors so you can hook two readers directly without a separate junction box. The unit includes a US plug with a 2 m connecting cable and a separate power supply cable/connector.
Rated output is 24 V DC at 3 A, with a rated range of 0 to 3.9 A — meaning it'll handle a steady 3 A load and tolerate peaks up to 3.9 A before the short-circuit protection kicks in permanently. That permanent short-circuit protection (not auto-recovery) is a deliberate choice: if the load goes short, the supply locks off until you clear the fault and recycle power. No guessing whether the breaker tripped. The IP67 rating means the whole cast housing — screws, M12 connectors, and all — is dust-tight and can handle temporary immersion in a meter of water. It's also Class II (double-insulated), so no ground wire needed — just the live and neutral. Galvanic isolation between input and output is SELV/PELV per EN 60950, which means the 24 V side is safe to touch and won't pass a fault from the mains. That's critical when you're wiring readers near operators or in wet areas.
Where you'd use it
This supply is purpose-built for SIMATIC RF600 RFID readers — the description says it's for use directly at the process, and the IP67 housing, M12 connectors, and four M5 screw mounting all point to a machine-mounted installation, not a control cabinet. You bolt it to the machine frame near the reader, plug in the readers, and run the mains cable back to a panel. Free convection cooling means no fan to clog with dust.
Safety approvals per EN 60950, UL 60950, and CAN/CSA 22.2 No. 950, 3rd Edition. EMC meets EN 61000-6-3 and EN 55011 Class B.
Physical fit and connections
Dimensions are 175 mm deep, 85 mm wide, 35 mm tall — about the size of a thick paperback. Mounting is via four M5 screws through the flanges. The input side has a US-style plug with a 2 m cable; the output side has two M12 4-pin, A-coded female connectors. If your panel or machine frame has the footprint, it bolts on directly — no DIN rail adapter needed.
