EM730 series voltage/current signal sensor
EM730 series voltage/current signal sensor
Product details
The EM730 series voltage/current signal sensor meets the requirements of GB28184-2011 "Fire Equipment Power Monitoring System". Adopting a card rail installation structure, it is installed locally in the power supply circuit of the fire-fighting equipment in the distribution box or distribution cabinet, and the power supply status of the fire-fighting equipment is continuously monitored 24/7. Quickly analyze faults such as overvoltage, undervoltage, phase loss, phase mismatch, overcurrent, and power interruption in the main and backup power supplies. Once a fault occurs, EM730 automatically reports the fault information and can perform linkage output or manual operation according to pre-set settings.
The EM730 series of sensors are powered by a 24V DC safe voltage, ensuring both personal safety and stable operation of the entire system.
■Monitoring function: Monitor abnormal voltage and current status of the fire power supply, including overvoltage, undervoltage, overcurrent, phase error, phase loss, power interruption, and other fault states of the main and backup power supplies
■Statistical function: Collect fault information and generate SOE records
■Fault/alarm function: light alarm
■Communication function: Through intelligent communication bus, information is transmitted remotely in digital form, with high anti-interference ability
■Other functions: self check important components; Store 64 alarm and fault records, which can be saved for 10 years after power failure
