Trident Mains Battery Charger Features

It has AC to DC isolation, a surge protector, automatic multistage charging and many other safety features.
Automatic Multi-stage Charging Curve—The Trident battery charger has an automatic max. Six-step charging curve that delivers nominal current for approximately 75% of the charging cycle. It ensures complete, fast, and safe battery charging.
The Built-in Timer will switch from absorption to floating stage according to either the current drop to the nominal level or the timer set value.
Dip Switches - Dip switches allow you to choose charge mode and battery type and support R/C or R/D.
Recycle Charging is designed to be permanently connected to the battery. After 14 days, it will automatically switch to recycle charging to eliminate possible sulphation in case of long-term floating.
Simultaneous Multi-battery Bank Charging - multi separate DC positive terminals (12A has two banks, 20A, 25A & 40A have three banks) allow charging multiple batteries simultaneously. The total current in the batteries is a maximum of 12A, 20A, 25A or 40A, depending on the model, divided amongst the batteries according to their discharge state. (NOTE: the multi outputs are not independently voltage regulated, so it is important to avoid systems with mixed types of batteries)
Isolated Design—The output banks have an electronically designed isolation circuit. This circuit prevents the current flow between banks and the flow backwards from the battery-to-battery charger.
