6EP3437-8SB00-0AY0 SITOP PSU8200 24V/40A 3AC Power Supply 960W | Siemens

The Original New Siemens 6EP3437-8SB00-0AY0 SITOP PSU8200 is a high-performance 3-phase stabilized power supply designed for complex industrial plants and machinery. It delivers a robust 40A at 24V DC with a wide-range 400-500V 3AC input, making it suitable for demanding automation and process control applications. The PSU8200 features Power Boost technology that briefly delivers up to three times the rated current, ensuring reliable system start-up even under heavy loads. With a high efficiency of approximately 94%, it minimizes power loss and heat generation, while the compact metal housing saves valuable cabinet space. This unit is designed for sophisticated solutions and offers maximum functionality for use in complex plants and machines.
