SITOP RED1200 Redundancy Module EX Input/Output: DC 24/48V/40 A suitable for decoupling two SITOP power supplies with a maximum output current of 20 A each. The SITOP RED1200 redundancy modules are the optimal complement for all 12, 24, and 48-V power supplies to ensure additional protection against power supply failure. The redundancy module decouples two identical 12, 24, or 48-V power supplies, so that in the event of a failure of one power supply, the supply to the consumers is still guaranteed by the second power supply. Through the redundancy modules, identical power supplies can also be connected in parallel for increased performance. No matter the industry or requirement - Siemens offers reliable and efficient power supplies for every system.
