Siemens 6EP1436-3BA00 Modular Power Supply Unit

Siemens SITOP modular 6EP1436-3BA00 is a 24 V DC, 20 A stabilized power supply designed for DIN-rail mounting in industrial control cabinets. It accepts a three-phase input of 400–500 V AC and delivers a regulated 24 V DC at up to 20 A, equating to roughly 480 watts of output power. As a member of the SITOP modular family, it is intended for reliable, modular use in automation environments and is listed with an optional substitute model 6EP3436-8SB00-0AY0 for certain configurations. The unit is housed with an IP20 enclosure appropriate for indoor electrical cabinets and is commonly used to power automation controllers, sensors, and actuators that require a stable DC rail. Notably, the 6EP1436-3BA00 has no built-in incoming fuse, so external overcurrent protection and proper wiring practices must be followed according to system design. Efficiency is typically around 90 percent, contributing to lower heat generation in crowded control panels. This model is sized to deliver a steady 24 V output while maintaining regulation under load changes, making it suitable for applications such as CNC machine tooling, packaging lines, and other factory automation tasks where a robust 24 V supply is essential.
