MRW-5450V4V-B1

450 Watt

  • Silent due to regulated fan
  • High efficiency up to 86 %
  • 2 power inputs

The mini-redundant MRW-5450V4V-B1 has been developed for server and storage systems. In case one power supply rack fails, the other one takes over the full load without any interruption. The subsequent exchange of the defective power supply rack during operation ensures a very high system availability. Separate mains supplies allow supply from different mains networks (UPS).
