    The Balmar MC-618H - Features That Matter:


    Announcing Integration with the SG200 Battery Monitor (You need an SG200 to utilize these new features)
    • Monitor Alternator/Regulator Activity from the SG200
    • Setup Regulator from 2″ Color Display or the Smartphone App
    • Advanced Programming from the Smartphone App
    • All the Same Regulation Features as the MC-614
    • New Carbon Foam AGM Battery Profile
    • Improved High Temperature Alternator Control
    • Protects Lithium Batteries below Freezing Temperatures

    Balmar has upgraded its legendary MC-614 Voltage Regulator to communicate with the SG200 Battery Monitor!  Same great features as ever only better and easier to program. Now you can see how the New MC-618 Regulator is directing your alternator charging activity from either the SG200 2″ Color Display and/or the optional Bluetooth® Smartphone App.  Basic setup functions can be accomplished from the SG200 Color Display, Smartphone App or the traditional on-regulator programming tool.  Advanced Programming functions are available and easily configured from the Bluetooth® Smartphone App.

    Monitor your Alternator’s Performance with Real-Time Data

      • Charging Stage
      • Compare Actual Voltage against Target Voltage
      • Monitor Field Output Percentage
      • Set Maximum Field Percentage
    Alternator Temp Sensing:

    When the optional alternator temp sensor is used the MC-618 will protect the alternator from over heating and the demand being placed on it.

    Other external regulators simply cut the alternator field output by 100%, when they are over heating. As such, competitors regulators will ping-pong back and forth off the high temperature limit;

    100% Output > Drop to 0% > Back to 100% > Drop to 0%, on and on and on

    This antiquated method of temp sensing digs into alternator performance and becomes very, very annoying. In contrast the MC-618's processor decreases alternator current in small increments until the optimum output is attained to maintain the temp at a safe level. As the alternator cools or accepted current drops off the output increases to maintain the highest output possible at all times.

    Dual Battery Bank Temp Sensing:

    With the optional battery temp sensor the MC-618 not just monitors the house bank for battery temp, but can also monitor your starting battery too.

    Belt Manager / Amp Manager:

    The Balmar regulators allow you to set the maximum field potential for current limiting the alternator to allow for better alternator cooling, longer alternator life or belt constraints. This is really one of the most useful features out there. For instance if you want to upgrade your alternator but can't afford the serpentine conversion right now, no problem buy that 165A alternator and simply reduce its output to handle your single 1/2" belt. When you finally install your pulley kit revert to a higher alternator output. Do want to maximize alternator life because you sail or venture far off the grid? No problem, buy the next size up alternator and reduce its maximum potential by 10% or 20%. Your alternator will barely break a sweat.

    Remote Voltage Sensing:

    The MC-618 features an additional non-current carrying positive remote voltage sensing wire so it can sense the actual delivered voltage at the batteries as opposed to the back of the alternator. When the regulator negative and regulator volt sense wires are fed directly to the bank being charged charging performance can be increased by 20%-40% or more when compared to self sensed alternators. The volt sense circuit allows the regulator to compensate for voltage drop between the back of the alternator and the battery bank.
