SINGLE-PHASE 20A ATS PDU DISTRIBUTES AND MONITORS NETWORK-GRADE POWER IN REAL TIME: This metered PDU provides real-time local reporting of the total load level via its built-in digital current meter. Ideal for network IT applications, small computer rooms and other equipment rack applications, the PDUMH20HVATS features eight C13 and two C19 200-240V outlets for connecting equipment. Outlets are factory-programmed for sequential turn-on at 250-millisecond intervals when the PDU is first energized to prevent inrush-related equipment interaction at startup. SWITCHES FROM PRIMARY TO SECONDARY POWER SOURCE IN MILLISECONDS: Dual 12-foot (3.7-meter) power cables with C20 inputs connect to separate primary and secondary mains circuits, backup generators, UPS systems or utility power grids, including out-of-phase sources. Dynamic solid-state automatic transfer switching (ATS) allows the PDU to switch to the secondary source within 2-5 milliseconds, should the primary source fail or become unstable, to ensure your connected equipment operates without interruption. An on-board ATS processor constantly evaluates the power quality of both input sources. It prevents switching if the secondary source is unavailable or of lower quality than the primary source. DIGITAL LOAD METER HELPS PREVENT POTENTIALLY EXPENSIVE OVERLOADS: A digital ammeter reports the total load for all connected equipment. Monitoring amperage helps ensure load levels remain well below maximum capacity with no danger of overload that could lead to costly downtime or damaged equipment. Maintaining proper load levels, even while adding new equipment, can keep your TCO (total cost of ownership) low. MOUNTS INTO 1U OF RACK SPACE: Use the included mounting hardware to install the all-metal housing into 1U of space in an EIA-standard 19-inch rack. TAA-COMPLIANT FOR GSA SCHEDULE PURCHASES: The PDUMH20HVATS is compliant with the Federal Trade Agreements Act (TAA), which makes it eligible for GSA (General Services Administration) Schedule and other federal procurement contracts.
