Battery Charging Units EBC1205M/EBC2405M/EBC1210M (SMPS Technology) ENKO Electronic Control Systems - IZMIR / TURKIYE Lead-Acid Battery charger (with Boost Charge and Alarm functions) EBC Series Battery Chargers are ENKO EBC Series Battery Chargers can deliver continuous charging designed and optimized for charg- current of 5A and 10A into 12V battery system with EBC 1205M and ing all types of Lead Acid batteries EBC 1210M (voltage is set to 13.8Vdc, with an option of up to (including gel type sealed Lead 14.7Vdc), and 5A into 24V battery system with EBC2405M (voltage Acid batteries), protecting the is set to 27.6Vdc with an option of up to 29.4Vdc). These battery battery and extending its useful chargers are designed with performance in mind and special care is life time. taken for protecting and extending the life-time of the battery. 195Vac to 264Vac input voltage range 45Hz to 440Hz input supply frequency range Capability to work direct from 240Vdc to 365Vdc supply voltage 13.8Vdc factory set DC output terminal voltage (option up to 14.7Vdc) for EBC 1205M and 1210M, 27.6Vdc factory set DC output terminal voltage (output up to 29.4Vdc) for EBC 2405M 5Adc continuous output current into load with EBC 1205M and 2405M, 10Adc continuous output current into load with EBC 1210M Capability to work continuously into short-circuit Parallel connection for higher output current rating and redundant operation Series connection capability for higher output voltage requirements No cooling fans used for high operational reliability Aluminum alloy case for robust handling and easy mounting ENKO EBC Series Battery Chargers are designed with “Switched Mode” technology, where the switching transistor has only two states, ON or OFF, which increases the overall efficiency, hence reduces the excess heat dissipation and in return, increasing the device life-time and reliability. 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 Charging LeadAcid batteries in three controlled stages for best performance... battery is limited in order to protect the cells and reduce damage to the plates. As the battery capacity is recovered, each cell voltage reaches up to 2.30Vdc to 2.45Vdc level, which means that the required charging current starts to reduce. When the required battery terminal voltage is fully reached, the charger keeps supplying just enough current in order to compensate Technical specifications: Input supply voltage range: Relative humidity: >82% under full load conditions Nominal output voltage: Additional features: EBC 1205M&1210M: 13.8Vdc (factory set, adjustable up to 14.7Vdc) EBC 2405M: 27.6Vdc (factory set, adjustable up to 29.4Vdc) Rated output current: EBC 1205M&2405M: 5.0A DC (Typical: 5.3A, Short circuit current: <6.0A) EBC 1210M: 10.0A DC (Typical: 10.6A, Short circuit current: <11.4A) Output voltage ripple: 10Hz to 100KHz — 50mV(EBC 1205M), 75mV(EBC 2405M), 100mV(EBC 1210M) pk to pk (noise: <1V pk to pk) <200mV (no load to full load) Line regulation: Charge fail output: Solid state output, sinking 50mA under normal operating cond.

Typical Cell charging characteristics Stage 1 Constant Current Charge (initial stage) Stage 2 Constant Voltage Charge (equalizing stage) Typical Cell charging characteristics of the charger is shown in the table. The Cell is part Stage 3 Constant Voltage Charge (float charge) of the battery, 12V batteries contain 6 cells and 24V batteries contain 12 cells. Factory setting of the charger allows each Cell to be charged to 2.30Vdc, which 24V systems. User can use an option up to 2.45Vdc per Cell, which corresponds to 14.70Vdc in 12V systems and 29.4Vdc battery terminal voltage in 24V systems. Cell...
