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).

Max output load must not exceed 450 W. Combined output current at +3.3 V and +5 V must not exceed 170 W. Ripple and Noise was measured by a 20 MHz bandwidth limited oscilloscope with connected 100 µF electrolytic capacitor and 100 nF ceramic capacitor.
As a power component this PSU is for assembly purposes only and must not be operated in unassembled condition. The final assembly has to comply with the valid EMC and safety standards.
