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...

The Paramode 4455, a follow up to the 7355 in the product line, has these voltage curves which show the sag under load.

The 7355 literature tried to say there was a flat top over the range and no sag, but we do see the sag, same as they show for the Paramode.

The little graph shows the no load flat top while charging a battery (not what I have seen!) but below in the table, they give "no load" and "full load" voltages where the full load is lower (The Sag in other words)
I owned a Paramode for a while and can confirm it sagged exactly as shown in the curves and similar to my 7355.
I question whether there is enough resistance from inside the unit, then along the 7355's fairly short #10 wires to the DC panel to create that amount of sag we see at the panel. I have not measured that, so Salvo's case has not been disproved and there is no reason to question his own measurements.
