When battery charger is disconnected from the mains, or battery is fully charged, a relay is used to automatically disconnect the charger from the batteries, to prevent the battery from flowing back (Backfeed).
U-shaped heat sinks which fit perfectly with the housing, dissipate heat in an effective way to ensure the charger with long life span.
The 48V lead acid charger works safely and silently. With the application of soft start technology, the output is spark free.
