Beta Controller - Sea Spec Engines
The BETA CONTROLLER is only offered as an option with
our 70 Amp or 100 Amp Iskra alternators. These uprated
alternators also include a polyvee drive (with a 6 groove flat
belt and pulleys designed for the increased power loading).
These alternators develop the following outputs:
a) 70 Amp Iskra alternator develops: 35 Amps at 'tick over'
increasing to 70 Amps at 2,700 rev/min.
b) 100 Amp Iskra alternator develops: 60 Amps at 'tick
over' increasing to 100 Amps at 1,800 rev/min.
The BETA CONTROLLER is an integrated battery charging
regulator. The controller provides a three stage charging
system enabling a rapid charge rate for batteries:

Installation
The Beta Controller has been designed for mounting off the
engine, in a location away from vibration, water and
condensation. Ideally, as there is a charge mode LED, the
unit should be positioned so it can be seen.
All goods are offered and supplied in accordance with our
'General Terms of Tender Sale'.
A.MODE B.MODE
RED L.E.D ORANGE L.E.D
A mode the first stage is a boost charge, when operating the
LED shows red.
B mode the second stage is where the voltage is at a high
level and the current is between 10% and 95% of the
nominal alternator current, the LED shows orange.
C mode the third and last stage is intended for maintenance
of battery voltage only. When the alternator current drops to a
low level for longer than 2 minutes, the regulating mode is
changed from B to C.
The controller automatically adjusts the charge mode to suit
the load and is set for conventional lead-acid batteries as
standard during production. It can easily be re-set for deep
cycle or gel batteries.
