Meanwell Rsp-500 vs progressive Dynamics 9245c-14.8
Any body familiar with both of these units , whats any pros and cons of each ?
Thanks
I've been wondering about your rsp-750-15 weird voltages and your powermax's weird similar behavior. Every try hooking the voltage sense wires on the Meanwell or have you given up on it?
I am not familiar with the pd9245-14.8, only the standard model which does only 14.4v.
PDs are nice because they are automatic, but with a push button manual override to force it to seek and hold 3 different voltages.
The PD9245 I had for a project would seek 14.56v and would only briefly hold over 40 amps over thick cabling to a hungry healthy depleted Lifeline AGM, on grid power. Other forums report that PD's maximum amperage on generator is well below expectations.
My Meanwell rsp-500-15 seeks at a constant 40 amps and voltage I choose for as long as I choose.
Have never run it on a generator.
40 amps available until voltage approaches my chosen setpoint, then amps taper.
I bet my Meanwell would outperform , to 80% and to 100%, a pd-9245-14.8 in side by side, all factors/variables being equal.
And with battery temperatures more than 20 degrees outside of the 77F range, the meanwell can be adjusted to compensate to prolong battery life.
I have recently acquired battery temperature data showing much higher than expected battery temperatures in my usage. hot ambient temperatures and constant discharge/charging are keeping it 5 to 15 degrees hotter than ambient, always.
40 amps into an initially 87 degree battery for a half hour had me lowering voltages significantly as battery approached 100f, but I choose to at least approach 'ideal' for maximum battery life.
Actual battery temperature data has been an eye opener, and has me rethinking my high amp blasting in high ambient temperatures via alternator or meanwell. Thankfully i can adjust voltage on both and thus indirectly amperage, and as always, i release flatulence, after a healthy garlic clam sauce undercooked pasta meal, in the direction of charging sources marketed 'smart' and 'automatic'.
But the PD is one of the better converters.
