The Mk 3 Rudman Regulator
Voltage
controlled bypass regulator with
digital interface.
Easy to use ASCII command structure.
Protect your advanced lead acid AGM batteries from over voltage conditions. Modern AGM type batteries
fail to equalize their charging voltages when charged in a series string. A Rudman Regulator on each 12 volts battery
or block of batteries will protect them from over voltage damage during the last phase of a charge cycle.
The easiest way to maintain a equal charge on any single battery during a charging cycle is to regulate
it's voltage. If all the batteries in your series string are at the same voltage during the Float stage of charging,
then they will be equalized as much as possible. AGM type batteries capacity vary during manufacture, and they
tend to get out of equalization during use during heavy EV cycling. The first battery to "fill Up" has
a higher resistance and then robs the other batteries of the charging current that they need to be totally charged.
Then during discharge the same happens to the first battery to be completely empty. So some batteries get damaged
from over voltage and thermal, and some get damaged from cell reversal and never fully charged. An AGM string has
very little "give" to it while finish charging. A battery bypass regulator gives the string the "give"
it needs to protect the first to get full, and to pass the unneeded power along to the batteries that still are
charging.
