The Siemens 6EP3322-6SB10-0AY0 LOGO!Power supply converts a 100-240 V AC (or 110-300 V DC) wide-range input into a stabilized, adjustable 15 V DC output rated at 4 A. It reaches 88.4% efficiency, provides 40 ms buffering time on power loss, and snaps onto a 35 mm DIN rail in an IP20, Class II enclosure for direct control-cabinet mounting.
The output voltage is adjustable from 10.5 to 16.1 V via an onboard potentiometer, so this unit covers applications that need slightly above or below the nominal 15 V rail, not just a fixed 15 V. It supports parallel operation of up to two units to increase available power, which matters if a load exceeds the single-unit 60 W rating. The 40 ms power-loss buffering time is a spec to check against downstream PLC or relay hold-in requirements before assuming ride-through on brief mains dips.
Sized for LOGO! logic modules and small 15 V DC loads such as relay coils, sensors, or signal circuits in control cabinets, machine builds, and building-automation panels where DIN-rail mounting and a wide 100-240 V AC input range are needed.
