Siemens 6EP1437-2BA00 Power Supply

Siemens 6EP1437-2BA00 SITOP POWER is a DIN-rail‑mountable, 24 V DC stabilized power supply in the SITOP PSU300S family that delivers up to 30 A for industrial control cabinets and automation equipment. It accepts three‑phase AC mains in the 400–500 V range (50/60 Hz) with a wide-range input specification of 340–550 V, and provides a regulated 24 V DC output suitable for PLCs, sensors, and actuators. The unit is designed for external mains protection because there is no internal mains fuse; use a three‑pole circuit breaker (per IEC 898), for example a 3RV1021‑1DA10 or equivalent, in the mains circuit. Mounting is DIN‑rail compatible, and the standard height is 150 mm; with the 90° mounting bracket fitted (as described for this model and related 2BA variants) the assembly height can reach 180 mm. This 30 A variant is intended for SITOP PSU300S deployments where a robust, stable 24 V rail is required in demanding environments, offering practical use in control panels powering PLCs, relays, and peripheral devices.
