Most data centers provide power source redundancy in order to ensure critical devices have no power related downtime. Many rackmount IT devices, however, are not designed to take advantage of power redundancy. Metered MD Automatic Transfer Switches (ATS) are ideal for single-corded network devices and entry-level servers that are not designed with power redundancy. MD meter of the ATS provides a local 3-digit RMS current measurement with accuracy ± ( 3% of the reading + 5 last digits ) RMS. It helps avoid current overload in a high density equipment environment.
