Lou, The HPN1004A power supply looks to be identical to the TPN1136A power supply, which was offered as an accessory to the Maxar and Moxy mobile radios when used as base stations. The front panels of the two power supplies have the same switches, indicators, and connectors, and the ratings, cabinets, and heat sinks are the same.
I have the manual for the TPN1136A power supply, which was offered in two versions. Version 1 has a TLN5274A regulator board, on which are two M9170 transistors. The chassis and heat sink contain three other transistors: Two M9244 and one M9677. Version 2 has a TLN5274B regulator board, on which are two M9642 transistors. The chassis and heat sink contain two other transistors: one M9639 and one M9807. I am providing the above information because I believe that your HPN1004A power supply may have identical innards as the TPN1136A. Let me know if either of the versions matches what is in your power supply, and I'll scan the schematic and parts list for that version and send it to you. 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Lou Aiken Sent: Saturday, September 08, 2007 1:15 PM To: [email protected] Subject: [Repeater-Builder] Motorola HPN-1004 A Power Suupply I want to make a modification to one of these things. Can anyone tell me where to get a copy of the schematic. It will save me a couple of hours if I don't have to draw it from scratch.
