THE AUTOMATIC SEQUENCING CHARGER™ (ASC™)

The ASC™ is a solid-state charge controller for use in PV systems with currents up to 16 amps. It is available in 12 and 24 volt models (6-, 36-, and 48-volt on special order only). Options include low-voltage load-disconnect, battery temperature compensation, and user adjustable setpoints.

THE ASC™ IS UL Recognized, CSA Approved, AND FM Approved*.

* Approvals may differ for special products.

Temperature compensation is generally recommended for sealed batteries or where batteries are expected to experience temperature variations of more than + 10° from 25°C during periods of charging. A small temperature sensor on a 10 foot lead monitors battery temperature and adjusts the charging thresholds according to battery temperature. The rate of compensation is -5mv/°C per battery cell from 25°C.

The ASC™ can be provided with an auxiliary relay. This relay can be used to protect the battery from low-voltage damage by disconnecting loads or by signaling a standby generator to start or stop battery charging. The relay is rated for 10 amps and provides the common, the normally open and the normally closed voltage free contacts. The relay consumes 30 ma when activated and is activated at 1.92 + .03 volts/cell and deactivated at 2.17 + .03 volts/cell. A separate terminal block is provided for connection.
