This buffer unit is a supplementary device for regulated DC48V power supplies. It buffers load currents during typical mains faults and load peaks. Working principle: In times when the power supply provides sufficient voltages, the buffer unit stores energy in integrated electrolytic capacitors. In case of mains voltage fault, this energy is released again in a regulated process. Bridging of mains faults without interruption: Statistics show that 80 % of all mains fault lasts for less than 0.2s. These mains faults are entirely bridged by the buffer unit. This increases the reliability of the system as a whole. Extended hold-up time: Once mains power fails or is switched off, the buffer unit will continue to provide the load current for a defined period of time. Process data can be saved and processes can be terminated before the DC power switches off. Subsequently, controlled restarts are possible.
