buffer power supply has been designed to ensure continuous supply for devices requiring 12 VDC or similar stabilized voltage (9.5...13.8 V). Its modern switch-mode converter shows 83% efficiency and provides stable low-noise DC voltage (the ripple and noise level below 120 mVp-p).
During normal operation, the output voltage is converted by the SMPS from AC power network, and the attached rechargeable battery is maintained in a charged state. In the case of a power network outage, the power is supplied by the rechargeable battery instead. There is a protection against battery deep discharge, which switches off the power supply when the voltage falls below 9.5 V.
