DIN rail-mounted battery charger EBC 2420

lead-acidswitching

Charging Lead-Acid batteries in three controlled stages for best performance SMPS technology for maximum efficiency and reliablity with minimum heat dissipation. EBC 2420M can deliver continuous charging current of 20A into 24V battery system (voltage is set to 27.6Vdc, with an option of up to 29.4Vdc) These battery chargers are designed with performance in mind and special care is taken for protecting and extending the lifetime of the battery. EBC 2420M is designed with “Switched Mode” technology. The control system is also designed in such a way that; battery is charged in three stages: Constant current mode (protecting battery cells) Constant voltage mode (reducing the charge current) Float charge (compensation of internal self-discharge) Constant current mode makes sure that; when the battery is drained down below its rated capacity, the high charge current flow into the battery is limited in order to protect the cells and reduce damage to the plates. Charging characteristics are compliant to DIN41772/ DIN41773; power limited. When the required battery terminal voltage is fully reached, the charger keeps supplying just enough current in order to compensate for the internal self-discharge (float charge). This ensures that the battery can maintain its high charge state and deliver its rated output current, when ever required. The charger is also designed to operate with Constant Power output, where full output power can be delivered into the load up to 60° C ambient temperature. The output power is linearly de-rated down to zero at 70°C.
