A short-time discharge of the battery is made to confirm that all the battery blocks and connecting elements...

Energy & Power Conversion Parallel (dual) operation The battery charger systems have the capability to be connected in parallel for multi module configurations between units of the same rating. The parallel connection of battery chargers increases reliability for the DC load. Complete DC UPS systems in parallel configuration System description The range is capable of operating in parallel as shown on Figure 8. The parallel connection of DC UPS improves reliability through redundancy. In order to operate in such configuration, each rectifier/charger is equipped with a blocking diode. The...
