Jim, If you'd like to have the complete instruction/service manual for the TPN1105A/TPN1106A Power Supply/Battery Charger/Battery Protection & Alarm system, you can order it from Motorola Parts for about $7. Ask for Part Number 6881104E92. If you plan to use, repair, or adjust a TPN1106 power supply, you really should have this manual.
You mentioned that your power supply is different. What is its model number? Look for a "TPNxxxx" number stamped somewhere on the chassis. I have a collection of Motorola power supply manuals, and I may be able to help. 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Friday, December 14, 2007 3:34 AM To: [email protected] Subject: [Repeater-Builder] Re: power supply / battery system for repeater site I want to thank all that helped guide me to Motorola TPN1105/TPN1106 schematics, back in July 2007. Although, these above schematics are not the Motorola Micor power supply, that I have. They are similar. I have a Motorola Micor power supply, with the float/equilize slide switch for an battery option. I understand from reading a MSR-2000 manual, the power supply can be set for Nicad or Lead-acid batteries. I was mostly interested in a battery cut-off circuit, so the power supply doesn't over charge the battery. Although, from reading the emails, a over discharge circuit should also be used. Does Xantrex or http://www.newmarpower.com/ have a cut-off & a over discharge circuit? My batteries are awaiting for the properly controlled charger, with as much details. Thanks & 73's, Jim Kh6jkg
