Specialty Concepts ASC-12/8-F > 8 Amp 12 Volt PWM Charge Controller
Options: Adjustable Set Points
Manufacturer Part Number: ASC-24/16 F
The ASC photovoltaic battery charge controller is ideal for 1-4 solar panel systems. This unit offers unsurpassed protection to your batteries from overcharging. This rugged unit holds the record for high reliability since 1981. The standard ASC is UL recognized and is FM approved for hazardous locations. The ASC is also CSA approved for Canadian markets.
The ASC will allow maximum array current to flow into the battery through a blocking diode, lighting the "CHARGING" light (LED), until the battery voltage reaches the charge termination set-point. At this point, a shunt transistor will turn on, shorting out the solar array, turning off the "CHARGING" LED and halting any further battery charging. When the battery voltage drops to the charge resumption set-point, the shunt transistor will turn off and charging will resume. The result is that when battery capacity is low, charging will be continuous. As the battery charges up, current will pass into the battery for shorter and shorter periods, until at full charge, it will pulse current into the battery to achieve and maintain full charge.
For Larger Arrays:
The ASC can be wired in parallel to sub-arrays. This method provides the added reliability of independent, redundant charge controls and allows for sequential charging.
ASC F Model - Adjustability:
The ASC may be ordered with the adjustment pot available to change the charging set-points if required. Load disconnect set-points are also adjustable for units with E-option (LVD / Gen. start).
