DESCRIPTION

DATAKOM SMPS series are fixed output voltage, currentlimited lead acid battery chargers specially designed for usein gensets. Thanks to their continuous DC outputs they mayalso be used in a vide range of industrial applications whereDC power is required.

The chargers are designed for permanent connection togenset starter batteries. When the battery voltage is belowthe float charge level, the charger provides constant current,nearly equal to the rated output current allowing a rapid

recovery of the missing charge. When the battery voltagereaches the float level, the charger switches to constantvoltage charge mode and maintains the battery fullycharged, providing the maximum battery life, withoutovercharging or gassing.

The unit has overload and short circuit protections. Thisfeature makes the units deliver only the rated current duringengine cranking or a short circuit condition. They do notneed disconnection during cranking. The high temperatureprotection of the unit reduces the output current in case ofoverheating. Thanks to their high efficiency, the self-heatingof the chargers is kept in minimum levels allowing operation

in warm environments.

The wide input voltage range allows the chargers to beused in most countries.

The rectifier fail output is provided as a standard feature.This is a semiconductor output pulling to battery negativewhen theunit is not operating. Thanks to this output, arectifier fail signal is provided for the genset controlmodule which will give an alarm in case of failure.

The units provide a boost chargeinput as a standardfeature. When this input is pulled to battery negative, the

output voltage of the charger will be set to the boost chargevoltage. This feature may be used temporarily to improvebattery life.
