Author Topic: MSR 2000 repeater power supply  (Read 1071 times)

I have a TPN1191A power supply that I'd like to use as a power source for repeater I'm building ( using two Motorola mobiles).

This power supply came from a MSR repeater;  Can I just connect the AC power to it and get 12 VDC out, or do any of the other connections make a difference? (I believe this supply has a 9 vdc board and a regulator board). 

I'm hoping this is plug and play but if not would like to know if it's possible to use this supply this way and what additional connections need to be made.

Thanks

If they're anything like MSF power supplies, they'll turn right on when you apply AC.  However, the MSF supplies run high (16VDC).  They might cook your voltage regulators over time.
