Equalization BATTERIES ARE DANGEROUS The EMBC-8025 is design to charge 24V SLA (Sealed Lead-Acid) battery of 10A to 200A (over 4KW of DC power). It is of UTMOST importance that you follow the instructions each time you use the charger. -
Page 8: Charge Voltage And Current
Charge voltage and current:- When the unit is connected to the battery (battery series), the charge current and charge voltage are as shown in figure 4.1 and figure 4.2 respectively. Bulk Absorption Float Figure 4.1: Charge current Bulk Absorption Float Figure 4.2: Charge voltage When the main voltage is removed, the output voltage on the main 24V output is shown in figure 4.3 Figure 4.3: Output voltage (mains voltage removed) - Page 9 When the mains voltage is restored, the unit will reset and start to charge the battery to be ready for the next power failure. ** NOTE: If EMBC-8025 Battery charger couldn’t detect any battery, kindly check the battery manually by using Multi-meter or contact us through our website. Battery’s minimum voltage must be 16V.
