I need to know what the voltage should be for a battery backup system for the MSR2000 repeater, can anyone help me on this, I do not have a manual for it. And does anyone know where to get these batteries??

Thanks!!

Is it a 30 watt unit or a 100 watt unit?

13 volts for most of them, DuraComm maks a isolator switch that works well with the standard MSR. without the backup battery supply.

The radio runs off 13.8 volts.
Some stations have the battery revert power supply and have the retecangular red & black jacks on the pannel with the coax conns.

The battery revert has a relay in it to transfer the 13 volts to the radio from the battery. Look for a part number on the power supply and a relay in the ps.

Both stations use the feroresonate transformer in the power supply and add two extra boards and the relay for battery revert.
