Battery chargers are meticulously designed and constructed to work under hazardous situations for railway applications. They are designed to operate in multi-voltage conditions. For car lighting batter chargers come with features like conventional cooled solid state, single phase, scr regulated providing constant current and voltage output. It has a display show charge data, programmed charge settings and error codes.
They assembled with specific number of charging batteries operating under multiple ac inputs. These chargers use a dual voltage transformer to operate in a multiple vac. Remote sensing and external temperature probe is provided to check the temperature, for a long battery life. They equipped with features like self-diagnosis to detect charger or battery problems. Delayed power up features to eliminate problems like power up surges. Scr regulations are provided to charge by voltage or selective current methods. Remote voltage sensing increases the accuracy of battery voltage. These chargers use ni-cd or ni-mh, and sealed lead acid batteries.
