The EISC can be powered by an AC voltage in the range of 8–24 V

capable of delivering 12 VA of apparent power. Two auxiliary power

AC Powered with Battery Backup

The EISC can also operate in the AC mode with a user-provided backup

battery supplying power, if the AC source fails. The EISC does NOT

charge the battery, so separate provisions are required for charging.
