Besides batteries Power Storage Europe offers DC Power Supplies as an energy source. Our Power Supplies are adjusted so that they can provide both charging current to the battery and can feed the user. Therefore we call them: DC charger / Power Supply. These Power Supplies are equipped with DIN-rail connections. In addition, we offer the DC charger / Power Supply in housing for 19" and 23” racks. DC Power Supplies are built specifically for evacuation systems according to the EN 54-4 standard. The third option we offer is a DC Backup Power Supply (DC-UPS). This DC Power Supply is installed in a steel cabinet with built-in maintenance free sealed AGM batteries.
