3 Amp Battery Charger

This is an obsolete product, no longer available for purchase.

Features

The model DSE5103 is a 3 Amp battery charger  designed for permanent connection to automotive batteries, maintaining them in a fully charged condition without overcharging. The charger is also capable of rapidly recharging the batteries at a current up to the full rated output.

The charger may also be used to supply a standing load attached to the battery. The charger output may be factory set to account for the standing load.

The charger is designed for reliability, ease of installation and accessibility during routine servicing.
It features radio frequency suppression and its smooth output linear mode design has a low ripple
voltage making the charger suitable for use with electronic equipment.

The charger has both Overload and Short Circuit protection features, achieved by limiting the current to a
safe value during these conditions. It will automatically recover after the condition is removed.

If a short circuit or a severe overload is applied such that the voltage falls below four volts for longer than 10 seconds, then the Charge Fail Alarm relay will energise and the charge fail contact will close.  If the charger is inadvertently reverse connected to the battery then the fuse-link on the circuit board will
rupture. This should be replaced with a 10A quick blow type.

The electronic control circuit ensures that the charger can remain operating during engine cranking and running, operating in parallel with the charge alternator where necessary.

The charger features a boost charge facility to enable rapid recharging of discharged batteries or to allow
periodic equalisation of battery cells. When the ‘boost mode select’ terminals are connected together the
charger output will rise by 0.35V per cell.

OPERATION

The charger will supply current
 to the battery until the battery terminal voltage is equal to the set float voltage, at which point only a trickle charge current is present. When the battery voltage falls due to a load being applied and the battery being discharged, the charger will once again supply current to restore the voltage of the battery to the float voltage.
