The Siemens SITOP PSU6200 6EP3433-7SB00-0AX0 is a 3-phase power supply accepting 400-500 V AC (or 500-550 V DC) input and delivering a stabilized 24 V DC/5 A, 120 W output with 91.2% efficiency. Output voltage is adjustable from 24 to 28 V, and the unit tolerates -30 to +70°C ambient with natural convection.
The 400-500 V AC/500-550 V DC input rating lets this supply connect directly to a 3-phase drive DC-link bus as well as standard 3-phase mains, which single-phase SITOP models can't do. SEMI F47 compliance (voltage-sag ride-through) is specific to this variant and matters for semiconductor-fab-adjacent installations with a defined dip-immunity requirement. The 150% overload capability for up to 5 s/min covers momentary inrush loads - contactor coils, solenoid banks - without oversizing the base 5 A rating.
Fits control cabinets fed from 3-phase 400-500 V distribution or a drive DC-link, supplying 24 V DC logic and I/O power where SEMI F47 ride-through or marine classification (ABS/DNV) is a project requirement.
