SP-4004D

0U Single Phase Monitored ATS

Customizearrow_downward
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. PDU reports real-time inlet and circuit-level energy monitoring with 1% accuracy.
