PSU Module
The Repeater’s internal PSU Module is a high efficiency 300w switched mode device that converts the
110V AC input to a range of DC voltages (28V, 15V and 6.45V) to power the internal active modules.
The PSU Module has a switch which allows it to be set in the “on” or “standby” position; setting the
switch to standby will disable the repeater.
Note!
In the standby position the PSU module and repeater are still connected to the AC power
supply but the PSU module is not operational. The PSU module on/standby switch is located on the
top of the PSU module.
The PSU Module is fitted with a rechargeable battery pack which will provide the Control Module with
enough capacity to send an alarm in the event of AC power failure. The PSU Module also includes
charging and supervision electronics for the battery backup function. The battery can be switched on
and off. The switch is placed adjacent to the PSU On/Standby switch on the top of the PSU module.
At delivery the back-up battery is connected; the battery is replaced by lifting the battery pack out of
its recess in the PSU module and disconnecting the cable.
The PSU module has four LED Status Indicators, A green LED indicates that
the input power to the PSU is functioning correctly.
Three red LEDs indicate the health of the three output voltages supplied by
the PSU.
