An electronic automatic energizing damping device for connection to a source of electrical energy to protect and safeguard continuously all the devices, instruments, equipment and systems, connected to the source. The device comprises a control stage and a power stage. The control stage monitors the operating conditions of both the A.C. line and the load energized by it via the power stage, in order to detect irregularities in any of the programmed parameters of the voltage or the current, and supplies control signals that regulate the power stage. The power stage supplies the energy of the network to the load, according to the commands of the control stage. The control stage features a voltage sensor circuit, a current sensing circuit, a comparison circuit to receive the output of the voltage sensor circuit and an energy relay control circuit. The power stage comprises a surge breaker and suppressor, and an optical interface circuit. An alternating current detector circuit and a zero detector circuit connect the power stage to the control stage.
