The Battery Saver Low Ripple (BSLR) is a power supply with a load power transfer function. Loads connected to the BSLR are powered by the vehicle’s battery when the AC power to the BSLR is OFF. When AC power is applied to the BSLR special circuitry within the Battery Saver transfers the load(s) to the Battery Saver output.This Battery Saver is unique in that there is no interruption of power supplied to the loads during power transfers.
