It is common for mission critical data center devices to apply primary and secondary power sources, however some network devices and entry-level servers are not designed with power redundancy. For single corded equipment, Austin Hughes‘ InfraPower Automatic Transfer Switches (ATS) provide dual power sources. If the primary source becomes unavailable, it switches to the secondary power source.
The ATS is bundled with an input preference switch allowing users to set the power source preference to supply the output. Sometimes the manual power input switching function is essential, especially during maintenance in data centers, according to Austin Hughes.
True RMS local AMP measurement is via a digital meter with blue LED display, allowing access to the aggregate load on the circuit. It prevents circuit overloads during equipment installation and allows the user to plan the capacity based on actual real-time current monitoring.
One ATS cost-effectively provides power redundancy to multiple pieces of critical equipment and is available in rack mount models with 8 to 20 IEC outlets.
