DATAKOM SMPS series are fixed output voltage, current limited lead acid and Nickel-Cadmium battery chargers specially designed for permanent connection to genset starter batteries. They maintain the batteries fully charged, without overcharging or gassing. Thanks to their continuous DC outputs they may also be used in a vide range of industrial applications where DC power is required. When the battery voltage is below the 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 voltage reaches the float level, the charger switches to constant voltage charge mode and maintains the battery fully charged, providing the maximum battery life. The chargers are designed in switchmode technology. Their rugged design allows surviving in harsh electromagnetic environments found in automotive industry. The unit has overload and short circuit protections. This feature makes the units deliver only the rated current during engine cranking or a short circuit condition. They do not need disconnection during cranking.

The high temperature protection of the unit reduces the output current in case of overheating. The low weight of the unit makes it ideal for use in highly vibrating generator control panels. The small dimensions allow compact panel design. Thanks to their high efficiency, the self-heating of the chargers is kept in minimum levels allowing operation in warm environments. The chargers are able to operate in parallel with the engine’s charge alternator and other battery chargers. Multiple units may be connected in parallel in order to obtain higher current ratings. The wide input voltage range allows the chargers to be used in most countries. The rectifier fail output is provided as a standard feature. This is a semiconductor output pulling to battery negative when the unit is not operating. Thanks to this output, a rectifier fail signal is provided for the genset control module which will give an alarm in case of failure. The units provide a “boost charge” input as a standard feature. When this input is pulled to battery negative, the output voltage of the charger will be set to the boost charge voltage. This feature may be used temporarily to improve battery life. The unit shows the output voltage and current on its display. The chargers have open chassis, metal cased design, suitable for bolt and stud mounting in an enclosed panel.
