ambient temperature is within the range specified.
Operation Without Batteries
Suitability without Batteries
Suitable for use in power plants with or without batteries.
Loss of AC Power
without Batteries
Loss of ac power causes
•
Controller DC power is lost
•
Controller alarm relays are activated (unpowered)
Recovery from
Loss of AC Power
without Batteries
Restoration of AC power causes
•
Rectifiers return to their configured voltage set point
•
Controller DC power is restored
•
Controller automatically return to its last configuration
Alarm relays reflect actual alarm states
