Control signal transmitter and energy management system

Abstract

To provide a control signal transmitter and an energy management system that can facilitate connection work to power lines.SOLUTION: A control signal of a base device 6 is transmitted via a bridge circuit 60A to a control slave unit 4 corresponding to power lines W20B, W20C related to the combination of "L2 phase-N phase". A control signal transmission unit 70 is configured by integrating the base device 6 and the bridge circuit 60A. Therefore, when a control signal transmitter 150 is connected to the power lines W20A, W20B, W20C, the base device 6 and the bridge circuit 60 can be connected at once by connecting the control signal transmission unit 70 to the power lines W20A, W20B, W20C without connecting the base device 6 and the bridge circuit 60A individually.SELECTED DRAWING: Figure 3
