    DTU ZD3030

    ZD3030 serial to cellular IP modem is widely used as data transmission terminal for power distribution remote monitoring and control system, such as Feeder Terminal Unit (FTU) Automation Solution, Distribution Terminal Unit (DTU) Automation, and Ring Main Unit Automation in the electric power distribution network.
    ZD3030 supports serial RS232 and RS485 (or RS422) ports, can conveniently and transparently connect power secondary equipment (FTU, DTU, Ring Main Unit, etc. )with serial port to a public cellular network. With GSM/GPRS/3G/4G LTE full band support, the on-site equipment could be guaranteed to stay connected or recovered from any unexpected interference. With Chilink’s s industrial design, higher EMS levels are tested to ensure the highest reliability for any harsh environment.
