Bob, Both power supplies have the same capacity and physical attributes. However, when I compared their respective schematics in the Power Supply Service Manual 6881094E30, I saw that the TPN1185 (Battery Charger) power supply has several connections to the station RF tray that are not used in the TPN1186 supply. J603-5, -6, -8, and -9 have no connection on the TPN1186 supply, but are wired to the RF Tray on the TPN1185 supply. These are AC Fail and overvoltage signals. It would be prudent to ensure that the appropriate interfaces on the CXB station side are wired or programmed to use these signals.
The Power Supply Service Manual 6881094E30 is still available from Motorola Parts for about $20. 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Bob Luttrull Sent: Sunday, August 17, 2008 1:19 PM To: [email protected] Subject: Re: [Repeater-Builder] MSF 5000 CLB and CXB THe one for the CLB is TPN1185A and the one in the CXB is TPN1186B. on the CLB it has a light for BATTRVRT and on the CXB it dose not.

Nevertheless, please advise the model numbers of the power supplies you have. 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] <mailto:[email protected]> [mailto:[email protected] <mailto:[email protected]> ] On Behalf Of Bob Luttrull Sent: Sunday, August 17, 2008 1:05 PM To: [email protected] <mailto:Repeater-Builder%40yahoogroups.com> Subject: [Repeater-Builder] MSF 5000 CLB and CXB HI All I have 2 repeaters one is a MSF 5000 CLB and the other is a CXB. I would like to know if there is a way to use the power supply from the CLB with battery backup in the CXB. I want to use the battery backup on the CXB. I have an new CLB power supply in the box with battery backup. Can it be done? ThankS Bob kd7ikz
