User Manual

MBF, Multi Band Repeater

PRODUCT DESCRIPTION AND USER'S MANUAL

The -48VDC version of the power supply is designed to turn off if the supply

voltage falls below -36V (±1V), not to drain the feeding battery. It will turn on again

as the supply voltage reaches -43V (± 1V).

Back-up battery

Backup Battery

There is a back-up battery installed in connection with the power supply. If there is a

power failure the battery will supply enough power to the Control Module and the

Fibre Optic Converter in the repeater to send information about the power failure.

The backup battery can be switched on and off separately. The switch is placed

adjacent to the main power switch on the power supply.

At delivery the back-up battery is connected.

The battery is replaced by lifting the battery pack out of the crate and disconnecting

the cable.
