The FLEPCHER's BC115 SLA charger is designed to ensure that the public address system batteries are always charged to minimise unanticipated events. It integrates with the majority of today's mainstream systems. It includes a 24V DC current controlled battery charger with a 15A capacity and innovative switching power technology, which can charge batteries up to 80Ah to 150 Ah. Depending on the battery capacity, the charging current and voltage will vary during the charging process. Three charging-stage modes are designed to ensure the SLA battery is fully charged in a less time-consuming manner, in order to keep up with the fast-paced applications. Over the course of the charging process, the current rate will be adjusted appropriately.
