SITOP PSE202U NEC Class 2 redundancy module Input/output: 24 V DC suitable for decoupling two SITOP power supplies Output power limited 100VA the redundancy modules SITOP PSE202U are the optimum supplement for all 24 V power supplies, in order to ensure an additional protection against failure of the 24 V supply. The NEC class2 redundancy module decouples two 24 V power supplies of the same type with a limitation of the output power to 100 VA, so that in the event of a power failure, the supply of the consumers via the second power supply is still guaranteed. In addition, a signaling contact is provided, which can be evaluated by a controller, a PC or control system. The redundancy modules can also be used to connect power supplies of the same type in parallel to increase the power output and provide redundancy at the same time. No matter which industry, no matter what requirements - Siemens offers reliable and efficient power supplies for every plant.This text is machine translated.
