The DongAh Elecomm 8,000W compact 2RU-high CWRS-4150A Power Shelf combines the benefits of increased power density with ease of installation and maintenance. The power system may be populated with up to four DRM-440 Rectifier Modules for power scalability up to 8,000W (-54V @ 148A). It also provides an SNMP interface, remote access via Ethernet, and 92% efficient rectifier modules.

The number of rectifier modules, load breaker size and battery breaker sizes are each configurable in this compact 2RU-high modular power system. Two separate AC input ports allow for AC redundancy and smaller input cords. The system is capable of charging and monitoring two separate battery strings.
