Siemens 6EP3344-0SB00-0AY0 SITOP PSU100E 48V 5A 1AC Power Supply

The Siemens SITOP PSU100E 6EP3344-0SB00-0AY0 is a single-phase AC power supply rated 100/230 V AC input and 48 V DC/5 A output, delivering 240 W at 92% efficiency with a 30 ms buffering time on power loss. Output voltage is adjustable from 48 to 54 V via potentiometer, and two units can be paralleled for higher power.

Selection Notes

The 48 V/5 A output and 240 W rating fit loads that a standard 24 V SITOP supply can't serve directly - DC motor brakes, some sensor/actuator networks, or auxiliary control circuits specified at 48 V. Two units can be connected in parallel to raise available power beyond 240 W, which is the path to take if a single 5 A output is undersized rather than switching to a different SITOP series. The 85-132 V and 170-264 V dual input range auto-covers both 120 V and 230 V mains without a selector switch.

Applications

Used where 48 V DC is the plant standard - telecom-adjacent equipment, some conveyor brake circuits, or auxiliary control loops - fed from single-phase 100-230 V AC mains.
