Description
The dual AC 2 power module provides surge protection for the library power
system and monitors the primary AC input power to determine whether it is
present and of adequate voltage. If the primary AC input fails or drops too low,
the dual AC 2 power module handles the failover to the redundant, secondary
AC input until the primary input is restored.
Each dual AC 2 power module includes both primary and secondary AC power
connectors, two breaker switches, and a convenience outlet rated at 2 amps.
LEDs indicate the status of the primary and secondary AC inputs and the
overall dual AC 2 module.
