Balmar CFII-12/24 Centerfielder II Charge Parallel Controller

Designed for use in applications requiring balanced charge control from two alternators and two regulators on twin engines, the Centerfielder-II makes it possible to utilize the combined output of both alternators to supply optimized charging to a single large battery bank. By monitoring the ignition and field voltages at port and starboard regulators, the Centerfielder-II determines when both engines are running, and directs field current from the master (starboard) regulator to both alternators. By controlling both alternators with the same field source, the Centerfielder-II ensures that alternators can work together in the optimum manner.
