Features Description
Deep Discharge Prevention
Prevents deep-discharge of the standby batteries by disconnecting the load
when the standby battery-voltage drops below 19 +/- 1V DC. A deep-
discharge can cause permanent damage to standby batteries. Preventing this
condition allows standby batteries to recharge for continued operation after
extended power outages.
Battery Backup
Provides battery power to the load when the AC input of the power supply
falls below the rated level. The voltage at the load remains within the
specified range during these switching-transitions.
Battery Boost
Boosts standby battery voltage to maintain a constant 22 VDC when the
voltage drops below the 22 VDC level.
Short-Circuit Protection
Provides a shut down on the load side of the power supply when the load-
current exceeds the maximum level.
Automatic Retry
Restores output to the load when operating conditions return to nominal
levels. This feature restores voltage levels at the load following conditions
such as over-current and AC restore.
Battery Impedance
Provides a trouble warning when the impedance of the battery reaches a level
that could prevent proper system operation.
Battery Supervision Battery presence and low battery voltage supervision
Ground Trouble Detection Ground Trouble Detection
General Trouble Relay All troubles are reported over the common trouble contacts.
5.25 Amp Power Supply
