Specialty Concepts ASC Charge Controls
The ASC is a solid state regulator that is encapsulated in epoxy. It is ideal for 12 volt photovoltaic systems with one to five solar modules, especially for outdoor and marine use, since it is protected from moisture or sea spray. Low-frequency switching prevents radio interference. A red light indicates charging and flashes when battery is near full. “A” models include temperature compensation to vary the full charge voltage as battery temperature changes. Order this feature if batteries are installed in hot or cold locations. “E” models have LVD. Dimensions: 4.7" x 2.55" x 1.5". UL listed and FM approved. 5 year warranty.

Specialty Concepts Mark III Charge Controls
The Mark III/15 is designed for rugged motor home use as well as small home power systems up to 15 amps. The Mark III/20 will control up to 20 amps. These units features highly efficient charging and low-frequency switching to eliminate radio interference. Digital display metering includes status lights and analog and digital voltage and current readings. They also features adjustable charge set-points and array and battery fuse protection and are designed to flush-mount in a wall cutout. To surface-mount the regulator, order the surface-mount box below. Wiring connections are made to the back of the unit. Dimensions: 7.5” x 4.25” x 2.25”. UL listed. 5 year warranty.

The ASC series of controllers by Specialty Concepts Inc., is a switching shunt type, negative ground voltage regulator for solar battery charging. Basic models available in 12VDC, with 4A, 8A, 12A or 16A PV ratings, and 24VDC, 8A and 16A ratings. The ASC has a simple, low component count, 100% solid-state design and is completely sealed against harsh environments. Standard features: factory preset voltage limits, aluminum surface mount case, lightning protection, barrier screw terminal strip accepts #12 AWG wire, red charging LED and a blocking diode. In addition, models are also offered with a battery temperature compensation sensor suffix A, low voltage load disconnect (LVD) relay-suffix E (includes an LVD-LED), or HVD optimized for sealed batteries suffix S. All are FM approved and UL listed. Five year limited warranty.
