| Abstract: | An on line DC uninterruptable power supply (UPS) scheme is presented. This scheme has AC/DC power fail warning and AC power overvoltage/undervoltage protection units . It is suitable for the remote terminal unit (RTU) of the control system and acquisition systems on distributed area (SCADA). The principles are described. The input circuit of preventer was proved. The improved circuit is proposed. |
