A far-distance remotely controllable rectifier with a back-up battery may be applied to any electric appliance that requires a rectifier, and particularly to a wireless phone or the like telecommunication equipment, to serve as an uninterrupted power supply. A replaceable and rechargeable back-up battery and a ring-controlled switch circuit are provided to the rectifier of this invention to keep the machine working in case of an unexpected failure of the civil power or in response to detection of a phone call from a far distance to a ring-controlled switch for effecting a continuous power supply. Under normal conditions, the civil power is used to charge the back-up battery as a stand-by power source.
