The SITOP PSU6200 6EP3333-7SB00-0AX0 is a 120 W 1-phase switched mode DIN rail power supply that provides a stable 24 V DC / 5 A output, widely used as the standard power source for SIMATIC PLC systems, distributed I/O stations, and general industrial automation equipment.

High-Efficiency Power Conversion

Operating at up to 93% efficiency, this power supply significantly reduces heat dissipation inside control cabinets, minimizing cooling requirements and extending the service life of surrounding components. The wide-range input of 85–264 V AC automatically adapts to global single-phase mains voltages. Output voltage is adjustable via potentiometer from 22.2 to 26.4 V DC to accommodate voltage drops in extended DC distribution networks.

Robust Industrial Design

Housed in a rugged metal enclosure, the unit withstands mechanical shock and vibration typical of machine-mounted applications. It delivers full rated power up to +50°C ambient temperature with natural convection cooling, derating to 70% at +70°C. Integrated protections include short-circuit, overload, and overvoltage safeguards. A green DC OK LED and a relay signaling contact (NO, 60 V DC/0.3 A) provide local and remote status monitoring, enabling integration into higher-level control system diagnostics.
