The Accupack LDR40MH24-RS with charging regulators are used for buffering 24-volt systems by connecting the line voltage and the installation to provide DC to equipment. In the event of a power failure, the “on board” sealed batteries supply the system connected to the outlet. The supply-duration depends on the load current. To provide the needed power and in order to maintain a wide input voltage range, a switch-mode power-supply is built in. That means for AC an input voltage range from 85 to 270 volts and for DC an input voltage range from 120 to 400 volts. Using the RS-232/ RS-485 interface, status messages concerning input-voltage, temperature and accumulators can be received. The LDR can be also controlled by electronic control units.
