SP-4004A
Prepared for the Unexpected with ATS
Add power redundancy to your system with Automatic Transfer Switching (ATS). Our ATS PDU continually monitors your primary power source and instantly switches to a secondary source when it detects an outage, without loss of power to your equipment. ATS automatically switches back to primary source when power is restored. Report real-time inlet-level energy monitoring and outlet-level power metering with 1% accuracy. Remotely switch 24x to 36x individual outlets for complete control of your equipment.

Automatic Transfer Switch (ATS)
Automatic transfer switch PDUs have dual inlets. The second inlet acts as the backup power source to provide power redundancy to equipment with only one power supply.
Outlet Current Meter
Current (A) is measured at each outlet
Outlet Switching
Each outlet is equipped with a relay to allow for manual or automatic switching. Sequential outlet sequencing built-in to minimize inrush current.
Relay Health Monitor
Proprietary firmware keeps track of key relay health indicators to alert the user of potential failures. Additional relay failure detection circuit allows for alerts when a failure occurs.
