Good Day All,
First of all thanks to all who have previously posted in the electrical
forum, searching for an answer to my question has been enlightening (even for a retired engineer).
I have recently acquired a used ARS-5 regulator
and when charging
in the initial "Bulk" phase I am getting voltages of 14.8-14.9 (measured by Link 10, analog meter, and a multimeter at the regulator's contacts). Admittedly the batteries (4 Trojan 105s) are fully charged from shore power
(off while testing). Trojan shows a 14.8v spec for charging
on their site, so I'm not really worried about them.
My concern, having read comments alluding to "bulk charge is full field" and tuning/dialing in smart regulators is required due to mfrs. dumbing down their default settings. The ARS-5 brochure shows a 14.6v default bulk setting for FLA batteries, while the voltage is programmable, I am not sure I should or would want to lower it as it would extend charging times.
Is 14.9 volts dangerous for marine electronics or a Danfloss compressor
(I could not find a maximum operating voltage on their site)?
I have replaced the 16ga. harness from my BRS II with the 14ga. for the ARS and all connections are good.
I have a 75A Balmar alternator
, so I am not worried about thermal runaway/over charging (acceptance rates/ Batt temp sensor should handle any issues).
I have not yet run it long enough to assess what happens when it transitions to the absorption phase.
The readings are identical w/wo Bat/Alt temperature sensors.
I am not interested in Mr Sterling's theories.
