**** Your Repeater Site AC Mains Power fails for what turns out to be a very extended amount of time. A large (but modest) capacity battery bank/system with no LVD (low voltage disconnect) powers the equipment until they run (down) flat and the system stops working (dies). [Of course it's a Friday before a 3 day weekend.] The AC mains power returns at some later time and the "standard" Astron 50 Amp Supply (or similar) tries to deal with charging the depleted/flat parallel battery bank. The battery bank will take all the restored Astron tries (and maybe does try) to deliver for quite some time before what might - can - may - does and/or could happen? s. > Heck my micor repeater is running fine on a 50 amp astron which > is float charging the three gelcell batteries that power the > repeater of course between the batteries I have the Motorola > power supply that takes 12 volts and gives the repeater all the > different voltages that it needs.
