144 W four-step DC/DC charger for lead-acid batteries; 12 VDC 12 A ICI 24-12 144

These intelligent battery chargers of ICI series operate a four stage charging cycle. The first stage monitors the battery to establish that the battery is in good condition before starting the three stage process. This feature is of key importance in ensuring that faulty batteries are not inadvertently charged causing overheating and potential system failure. The units are also reverse polarity protected and when re-connected correctly will operate normally without reset. The Alfatronix three point mounting cradle is also supplied for fast and easy installation.

While many applications can be supplied using a standard voltage converter or stabiliser, sometimes there can be a requirement to charge one DC battery from another in order to provide independent power. The Alfatronix range of DC-DC chargers are based on the very successful PowerVerter range but configured to offer a four stage charging program that will ensure that batteries are charged to a maximum capacity providing long term reliable power.

These products come with many of the same safety and protection features as the PowerVerters, but are also additionally designed to detect faulty batteries and dead cells. They will also ensure that they will not operate unless the source battery is attached to a charging source such as a vehicle alternator or mains unit. In this way, you can ensure that the charger will not allow unintentional draining of the source battery.

Phase 1: Monitoring the battery to establish that the battery is in good condition before starting the three stage process.
Phase 2: Charging with constant current to 80 % of cull capacity.
Phase 3: Charging with constant voltage to 100 % of capacity.
Initiated with constant maximal current followed by time-controlled constant voltage charging with timer.
Phase 4: Automatic switch to trickle (floating) charging which keeps charge at 100 %
