Siemens 6EP1437-3BA00 SITOP modular power supply provides a regulated 24 V DC output at up to 40 A (960 W) for control circuits, PLCs, sensors, and actuators in industrial automation. It accepts 320–550 V AC 3-phase input at 50/60 Hz, is IP20 rated, DIN-rail mounted, and measures approximately 240 × 125 × 125 mm; parallel operation is supported for redundancy. Designed for SIMATIC systems and industrial environments, this high-efficiency switch-mode supply operates from 0°C to 70°C and is available as a phase-out with replacement (SITOP PSU8200); common replacements include 6EP3437-8SB00-0AY0 and 6EP1437-3BA10.
