Upgraded power supply system now protects against hour-long power failures

Siemens has upgraded its Sitop PSU8600 power supply system with the addition of new supplementary modules to transform it into an uninterruptible direct current (DC) power supply. To achieve this, the new DC UPS module UPS8600 uses the energy stored in BAT8600 battery modules to keep the system up and running in the event of a power failure, and it extends the previous bridging times enabled by the buffer modules from just minutes to hours. The PSU8600 has up to 36 outputs capable of being adjusted between 4 and 28 volts, and all of these can be buffered in the event of a power failure. To maximize buffering time for important loads, it is also possible to selectively shut down certain outputs. The Sitop PSU8600 is particularly suitable for use in applications which place stringent demands on reliability and simple integration, such as the automotive, food or pharmaceutical industries, and in the field of plant and special-purpose machinery building. The enhanced availability with the new UPS8600 makes the power supply ideally suited also for process applications such as in the chemical, oil or gas industry.
