What it is and where it fits
The Siemens 6GT2898-0AC81 is a wide-range AC/DC power supply from the SIMATIC RF600 family, purpose-built to power SIMATIC RF identification readers directly at the process. It takes a single-phase 100–240 V AC input and delivers a regulated 24 V DC output at 3 A, with a rated range of 0 to 3.9 A for transient headroom. The IP67 rating means the entire enclosure — including the Mini-Change® input connector and the two M12 output connectors — withstands washdown and dust ingress, so this supply mounts right on a conveyor frame or near a read station without a separate cabinet. Free convection cooling keeps it silent and maintenance-free.
Key ratings and what they mean for your line
The 3 A continuous output at 24 V DC is sized to drive up to two SIMATIC RF600 readers directly, as stated in the suitability note. The 90% efficiency keeps heat dissipation low in a sealed IP67 enclosure — important when the supply is mounted in a warm zone near motors or drives. Output is short-circuit proof with permanent protection, and overvoltage protection clamps at Uout nom +20% typ. Galvanic isolation between input and output is SELV/PELV per EN 60950, so the 24 V DC side is safe to touch and compatible with standard industrial sensors and PLC inputs. EMC compliance to EN 61000-6-3 and EN 55011 Class B means it's suitable for residential and light-industrial environments without additional filtering — a plus when the supply shares a panel with sensitive RF readers.
Lifecycle and sourcing reality
For a BOM line or a line-down replacement, the 6GT2898-0AC81 is a straightforward drop-in for any SIMATIC RF600 installation. The wide input range (100–240 V AC, 50/60 Hz) means it works globally with no voltage-selector switch.
Mounting and integration notes
Mounts via four M5 screws through its 85 mm × 175 mm × 35 mm footprint — no DIN rail, so plan for direct panel or machine-frame attachment. The Mini-Change® input connector accepts a pre-wired cable (ordered separately for EU, US, or UK plug types). Two M12, 4-pin, A-coded female outputs feed the readers. Operating temperature range of -25 to +75 °C covers most factory-floor conditions; storage and transport range extends to -40 to +85 °C. Class II (protective insulation) means no earth connection is required on the input side.
