   * Available in 4, 8, 12, and 16 amp versions
   * Available in 12 volt and 24 volt (6 volt, 36 volt, and 48 volt on special order)
   * Guaranteed to FULLY CHARGE a COMPLETELY DEAD battery

MADE IN AMERICA WITH A 10 YEAR WARRANTY
Features
  • Recognized by Underwriters Laboratories (UL): Meets all requirements for UL 1741.

    Factory Mutual (FM) approved: For Class 1, Div 2, Groups A, B, C and D hazardous locations

    Canadian Standards Association (CSA) approved: For Class 1, Div 2, Groups A, B, C and D hazardous locations



    Efficient: Over 99% efficiency when charging.

    Full Charging: Ensures that the batteries are always topped off.

    Battery Safe: Charging method maximizes battery life.

    Reduced Maintenance: from healthy charging and reliable operation.

    Temperature Compensation: Remote sensor provides best charging for hot or cold locations.

    High Voltage Shut-off: Shuts off only when battery is full.

    Robust Circuitry: Control function 100% solid state.

    Automatic Load Shutoff: Protects battery from deep discharge.

    Generator Start or Alarm: Includes N/O, N/C, COM voltage free contacts.

    Simple, rugged electronics: low component count and streamlined design ensure long term reliability.

    Maximum environmental protection:Ideal for outdoor mounting

    No Minimum Voltage Required: Can charge a dead battery.

    Lightning protection: Survives most indirect strikes.

    Reverse leakage protection: Prevents power loss at night.

    Terminal Block: for sound and easy wire connections.

    Minimum RF Noise: Low switching frequency lessens electronic noise.



    INSTALLATION INSTRUCTIONS:

    The ASC may be mounted in almost any indoor or outdoor location. The unit should be mounted as close as possible to the batteries to avoid errors in battery voltage reading.
     The ASC may be mounted on the rear of the solar panels using outdoor-type double-stick foam tape. On units with temperature compensation (Option-A), 
    the ASC should be mounted within 10 feet (3m) of the batteries to enable the sensor cable to reach the battery.

    PROTECTION REQUIREMENTS:

    The circuitry of the ASC is encased within hard epoxy resin that offers substantial protection from the environment.

    The unit should not be mounted in direct sunlight or close to any heat generating source to avoid extreme temperature increases. The rear of the unit should not be blocked to allow air flow for adequate cooling.

    The exposed terminal block is made of corrosion resistant nickel plated brass. This will endure most outdoor environments. When the ASC is in an excessively corrosive location, a coating of an oxide inhibitor should be applied to the terminals.

    The optional sensor and cable need to be protected from damage (cuts, impacts, rodents). If the sensor or cable is damaged, the ASC will not operate. (Refer to Options section: OPTION - A)

    When possible, use stranded wire rather than solid wire. Stranded wire is less likely to fail and cause loose connections over time. Consider using wires of different colors to indicate source or polarity. Also, select a wire that offers the appropriate insulation for the condition of the location. (Refer to the U.S. National Electrical Code)

    Select wire of sufficient gauge to safely handle the rated current of the system and to limit voltage drop. The ASC terminals accept up to 10 gauge stranded bare wire (and 12 gauge solid wire). (When using 10 gauge stranded wire, divide the end wires into two equal sections and straddle the terminal screw). An alternative to using larger wire is to use two wires in parallel for each connection.

    WARNINGS

    Electricity, even low voltage electricity, can be dangerous. Installation should be performed by a licensed electrical contractor or other qualified personnel only. The requirements of the U.S. National Electrical Code should be followed.

    Follow all safety precautions of the battery manufacturer. Proper ventilation must be provided for the batteries. Most batteries produce hydrogen gas when charging, which is extremely explosive. Provide adequate battery ventilation. DO NOT expose the battery to open flame, matches, cigarettes or sparks.
