The Siemens 6GT2790-0DD03 is a charging station from the SIMATIC RTLS accessory line, built to charge up to 10 RTLS4083T transponders simultaneously via spring contacts with a magnetic retainer. It's a desktop unit that can also be wall-mounted, and it ships with a power supply unit and a C13 power plug for 100–240 VAC input. The station outputs 5 VDC at up to 6000 mA to the charging contacts.
Form factor and physical fit
The enclosure is molded in Ti-gray PC 10 GF plastic, sized at 298.4 mm wide, 180.6 mm deep, and 83.2 mm high. It's rated IP00, so it's intended for indoor, controlled-environment use — not washdown or dusty areas. The 11 electrical connections include a P1J barrel jack (ID 2.1 x OD 5.5 mm) for the incoming DC supply and 10 spring-contact pads for the transponders.
The 6000 mA maximum draw at 5 VDC is the total budget for all 10 charging slots — each tag pulls its share during the charge cycle. The IP00 rating means the unit has no ingress protection; it's a benchtop or wall-mount station for a clean, dry environment like a tool crib or a technician's bench.
