Internal Power Supply
The internal power supply of the Elite-RS Panels meets UL 864, 9th edition and provides a 5.25 Amp,
off-line switch-mode power-source for operating FACP functions as well as charging the standby batteries.
The 5.25 Amp power supply can operate at 120 or 240 VAC. A jumper connection is provided on the power supply to
switch between these operating voltages. Connecting the jumper provides 120 VAC operation and removing it
provides 240 VAC operation.
Reference Appendix C, Calculations to determine load current limitations of the 5.25 Amp power supply.
Features of the power supply include:
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 voltage when the battery voltage drops due to a low-battery condition.
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 battery depletion.
Status
The AC input to the power supply is supervised by the Elite-RS Panel.
The control panel provides an LED status display for normal and fault conditions.
Normal conditions occur when the power supply is operating in an acceptable
range. Fault conditions occur when the power supply is not operating in an accept-
able range.
