Feature introduction
Telemetry function: It can detect AC analog quantities such as voltage and current, and DC analog quantities such as battery voltage and temperature.
Remote signaling function: It can detect status information such as switch status signal, switch energy storage signal, battery low voltage alarm, etc., and has dual-position remote signaling processing function to support remote signaling displacement priority transmission.
Remote control function: radio frequency wireless remote control opening and closing. Equipped with a local/remote selection switch, which can be connected to the master station to remotely control the opening and closing.
Fault detection function: configure single-phase grounding, three-stage phase-to-phase protection, overload, anti-inrush current protection and other protection functions, and record the protection current.
Communication function: with serial port and network communication interface, built-in 101, 104 and other power industry standard communication protocols, can upload data to the master station through optical fiber/Ethernet, GPRS/CDMA, etc.
Self-diagnosis and self-recovery function: with self-diagnosis function, when internal software and hardware abnormalities are found, they can be recorded and reported in time, and the software has the function of self-recovery after power-on.
Power management function: support dual-channel AC backup power supply, use battery as backup power supply, and use soft switching technology to cut in seamlessly. When the main power supply fails, the backup power supply can be automatically and seamlessly switched on; it has the function of battery activation management, which can be realized automatically and manually Charge and discharge the battery.
