parallax power supply 7345ru parts PWM
My 7345 is not charging the coach batteries but does supply 12power to all accessories. The transformer, fan and relays work fine. Think i need a PWM circuit for it. Contacted PP tec support and th...

BFL13, thanks for bringing up those Parallax links again for us ... I've looked at them many times through the years.
You're right, my 7345 unit DOES NOT hold it's terminal output voltage up as those curves' show that it is supposed to ... if it did my AGM batteries would charge up even faster.
The sag shown for the Paramode 4455 better resemblies my 7345's voltage sag versus load performance.
By the way, do you have data yet proving that other (reasonably priced) RV chargers in their boost modes in fact are holding 14.XX terminal voltages under heavy currents?
