BETA CONTROLLER
SEA SPEC ENGINES
The BETA CONTROLLER is an integrated battery ch arging external regulator. It
is designed to be used with Beta s 70 and 100am p Iskra alternators.
The system utilises a three
stage charging characteristic which optimises the rapid
charge of battery systems.
The first stage (A mode) is a boost charge, which is indicated by the indicator LED
showing red.
The second stage (B mode) is where the voltage is kept at a high level and where
the current is between 10% and 95% of the nominal alternator current, the LED
shows orange.
The third and last stage (C mode) is intended for maintenance of battery voltage
only. When the alternator current is under a predetermined value for a time greater
than 2 minutes, the regulating mode is changed from B to C mode.
The system automatically adjusts the charge mode to suit the load and is set in our
works for conventional lead-acid batteries. It can easily be re-set for deep cycle or
gel batteries. A more detailed specification can be obtained from BETA MARINE.
