CH5A series are fixed output voltage, current limited lead acid battery chargers specially designed for use in gensets. It is also be used in a wide range of industrial applications where DC power is required. The same unit operates as 12V or 24V by manual selection on terminals 8 – 9. The chargers are designed for permanent connection to genset starter batteries. 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, without overcharging or gassing. The overload and short circuit protections make the unit deliver only the rated current during engine cranking or short circuit. It does not need disconnection during cranking. The high temperature protection reduces the output current in case of overheating, allowing operation in warm environments. The rectifier fail output 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 “fast charge” inputs as a standard feature. When this inputs 3 – 4 are closed, the output voltage of the charger will be set to the boost charge voltage.

Description

Automatic Battery Chargher CH5A 5 Amp. its able to work on 12 volt batteries and 24 volt, just by sellecting from terminals on the CH5A unit. also the fast and flot charge selectble from the terminals on the unit.
