Charge regulators ARS-4 and MC-612
Start delay and soft voltage ramp A time adjustable start delay and soft voltage ramp ensure minimal engine and belt fatigue. 4-step charge characteristic At the end of the bulk phase, the batteries are charged during 36 minutes at high voltage. This additional step in the charge curve is used to bring the battery as quickly as possible to a 80-90% recharged state. The normal absorption period starts after this “fast charge“ phase. (see advanced charge curve on page 1) All time and voltage values are adjustable ARS-4: system time and voltages. MC-612: all time and voltage values individually. Lower output amperage setting The field current can be programmed to reduce the output (MC 612 only), or be reduced to 50% with a switch (both models). These features can be used when engine reserve power is limited or in case of chronic belt slippage. Three protections against overheating A high current can cause overheating. Three temperature sensors can be wired to a MC 612 regulator: 2 for the batteries and 1 for the alternator. (ARS-4: alternator sensor only) Temperature compensation Batteries get hot when charged at high rate. Temperature compensation (the charge voltage decreases with increasing battery temperature) is a must in case of high rate charging to prevent thermal runaway. One of the two battery temperature sensors of the MC 612 is also used for temperature compensation. Voltage sense: measuring the charge voltage directly on the battery Some voltage drop is inevitable in case of high currents. The result will be a lower voltage at the battery terminals, and therefore also a lower charge current. The voltage drop can be compensated for by increasing the output voltage of the alternator. Voltage sense is needed for this feature. (available on MC 612 models only) Alarm and advisory information Dash lamp: over voltage, under voltage and temperature alarms. MC 612 only: additional
marine terminal for status information. Easy to install, and back up internal regulator (6-series alternators only) A cable harness for easy installation is included. The 6-series alternators have an internal constant-voltage regulator that does not need to be removed when connecting an intelligent external regulator. The internal regulator remains available as a back up if ever the external regulator would fail.
More current on board Duo Charge
For charging a second battery, independently from the main battery. The Duo Charge is suitable for both 12 V and 24 V systems, has 4 built-in battery programs and a battery temperature sensing option. The maximum output is 30 A.
Centerfielder
For the highest charge current. The Centerfielder enables two alternators to work together to supply a balanced charging current to a large battery bank. Suitable for both 12 V and 24 V systems.
