Intelligent -48VDC Power Distribution, Remote Management, Power and Environmental Monitoring

Server Tech -48VDCRugged, Reliable Rack Power Distribution for -48VDC Applications

The Sentry Switched -48VDC Rack Power Distribution Unit (CDU) minimizes the impact of locked-up routers, servers and other network devices for mission critical networks.  CLEC’s, ILEC’s, and ISP’s use Sentry -48VDC CDY’s to manage equipment in remote sites, co-location facilities and network operations centers.  Remote devices that are locked-up can be easily rebooted without the need to send a technician to the site.  Key applications include power distribution and remote management for a cabinet with -48VDC powered switches and high-amp network equipment.

The Sentry -48VDC Switched products provide power distribution and remote power management in a compact 19″ rack-mount enclosure.  other features include always-on technology for the highest level of fault tolerance, grouping of outlets to ensure that multiple supply deices come up at the same time across A and B power feeds, and linking for cost savings and doubling the number of outputs available on a single IP address.

The Sentry switched products for -48VDC feature fused power output protection.  Each low and high current output are individually protected by their own fuse.  A variety of current capacities are available.  Both the low current GMT and high current TPC fuses have a visual indicator when blown.
