![]() ![]() ![]() That +10VDC supply is also fed aside to initiate the creatig of a +5VDC supply. That supply then feeds into the U1 3 term regulator with its 10VDC output as the ( YELLOW ARROW PATH ). The 10 VDC supply is derived from the YELLOW transformer winding, as it initially passes as AC down the ( GREEN ARROW PATH) until it reaches the DC rectifier diode D5 and transitions out of it as a DC supply. The unit is using a conventional no frills power transformer that generates a basic 15VDC main supply from the BLUE transformer winding, That divides on down to a 5V logic supply BUT is being interlocked with having a +10VDC supply presence. From what has been told to me by your post, see if this info fits your unit.Īlso I can differentiate even further, by knowing if your back up battery is using 3 cells or a 9 V battery.
