The A46/A46F is a completely automatic, solid state, constant voltage Battery Charger built to carry continuous and intermittent loads up to 80% of its maximum rated output capacity. It automatically senses the Battery and Load conditions and delivers the necessary amount of charge. Once the Battery becomes fully charged, the output current will automatically decrease to a very low Trickle Charge to prevent overcharging of the Batteries. The A46/A46F is designed and built to charge Flooded Lead-Acid or Nickel-Cadmium Batteries containing a specific number of cells. However, it is not suitable to charge sealed Valve-Regulated Batteries since these require output filtering such as a Power Supply (see our model A12B for this type of application). The front panel Float/Equalize switch is provided to manually initiate a periodic equalize charge to optimize Battery longevity. This operation can also be achieved automatically by selecting one of our Electronic Equalize Timer options; either by itself or combined in our Digital C.A.P. (Combined Alarm Package) System that incorporates several Alarm contacts and status LED's. Other discrete Alarm packages are also offered in lieu of the integrated C.A.P. System when limited Alarm monitoring is sufficient for your requirement. The A46/A46F
