Siemens 6EP3321-6SB00-0AY0 LOGO!Power 12 V/1.9 A Stabilized Power Supply

The Siemens LOGO!Power 6EP3321-6SB00-0AY0 is a stabilized 12 V DC power supply rated for 1.9 A output, built for a 100-240 V AC or 110-300 V DC input. It delivers 22.8 W at 81% efficiency, holds output voltage within a 3% tolerance, and carries NEC Class 2 certification per UL 1310 for low-voltage limited-power circuits.

Selection Notes

At 12 V/1.9 A this sits below the 24 V LOGO!Power variants used for standard field I/O — pick it specifically when the downstream load, such as indicator lamps, low-voltage sensors, or small relays, needs 12 V rather than 24 V. The NEC Class 2 certification per UL 1310 lets it wire into low-voltage limited-energy circuits without additional overcurrent protection in NEC jurisdictions. Its 1.9 A/22.8 W rating is a fraction of the higher-current 24 V LOGO!Power units, so move up to a higher-current supply once the connected 12 V load exceeds a few watts, since more current at 12 V draws proportionally more input power than the same wattage at 24 V.

Applications

12 V sensor and indicator circuits, small relay coils, retrofitting legacy 12 V control loops, and LOGO! accessory power.
