You're referring to the TPN1106A power supply, which is part of the "C29" option on Micor stations. It can be adjusted for either nickel-cadmium or AGM/VRSLA batteries, and it is designed to transmit an alarm tone over the air when AC power fails and another alarm tone when the voltage has dropped to the cutoff point at which the repeater will be shut down. Of course, the float voltage must be adjusted for the specific battery chemistry used.
The entire manual for this unique power supply and Battery Protection and Alarm system is available in Publication 6881104E92, still a bargain at less than $6 from Motorola Parts. Just the schematic is available here: <www.repeater-builder.com/micor/pdf/tpn1106a-schematic-and-9.6v-reg.pdf> 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Maire-Radios Sent: Monday, January 29, 2007 2:59 PM To: [email protected] Subject: Re: [Repeater-Builder] Micor base/repeater on battey backup? There is a power supply that is made to take in 12V and it has the place for the battery. It is a Motorola power supply made for the repeater. ----- Original Message ----- From: twoway_tech <mailto:[EMAIL PROTECTED]> To: [email protected] <mailto:[email protected]> Sent: Sunday, January 28, 2007 10:12 PM Subject: [Repeater-Builder] Micor base/repeater on battey backup? I seem to recall the Micor base and repeaters have a wierd power supply voltage (around 15VDC). Has anyone had any luck running them off of 12VDC battery backup? My boss has a Micor repeater and we never could get it to work with batteries becuse of the power supply voltage it was looking for. Any Ideas? Thanks, Jordan
