Description
The Siemens 6EP1437-3BA10 is a SITOP PSU8200 Industrial Power Supply, a high-performance 3-phase switched-mode power supply designed for demanding industrial automation applications. This power supply delivers a stabilized 24 V DC output with a rated current of 40 A, providing a maximum output power of 960 W. It features a wide input voltage range of 320–575 V AC (3-phase) with active power factor correction (PFC) for efficient energy usage. The compact metal housing with IP20 protection is designed for standard DIN rail mounting. With high efficiency (typically ≥ 91%), excellent dynamic overload capability (150% for 5 seconds), and comprehensive protection features including short-circuit, overvoltage, and overtemperature protection, it is ideal for supplying reliable DC power to PLC systems, drives, sensors, and actuators in harsh industrial environments.
