Open type AC current transmitter DC4-20m output 485 communication

Open communication transmitter "usually refers to a device used for measuringAC power consumption (such as AC voltage, AC current, active power, reactive power, power factor, etc.)The equipment that converts it into standard DC signals (such as 4-20mA, 0-5V, etc.) is mainly used to safely isolate high voltage, high current and other strong electrical signals and convert them into weak electrical signals that are easy to collect, transmit and process. It is widely used in scenarios that require monitoring, controlling and measuring AC power parameters.

Open type AC current transmitter DC4-20m output 485 communicationTypical application scenarios:

1、 Industrial Automation and Control Systems

In industrial production, various types of motors, pumps, fans, and other equipment rely on AC power to operate. Open AC transmitters can monitor the power parameters of the equipment in real time, providing data support for automation control

Motor operation monitoringMonitor the AC current and voltage of the motor, determine whether the motor is overloaded, out of phase, or has abnormal voltage, and avoid equipment damage (such as monitoring the motor current through a current transmitter, triggering an alarm when the current exceeds the rated value, and promptly stopping the machine for protection).

Production line power monitoringIn production equipment such as assembly lines and machine tools, power transmitters are used to monitor the active power of the equipment, calculate energy consumption, and optimize load distribution to achieve energy-saving control (such as adjusting equipment operation timing based on power data to avoid overload during peak periods).

Frequency converter matchingUsed in conjunction with a frequency converter, it monitors the AC voltage and current output by the frequency converter, feeds back to the control system to accurately adjust the motor speed, and adapts to different production load requirements (such as conveyor belt speed adjustment).

2、 Power System and Distribution Monitoring

Open AC transmitters are the core equipment for power parameter monitoring in factory distribution rooms, substations, and building distribution systems

Monitoring of high and low voltage distribution circuitsIn the low-voltage distribution cabinet, the current and voltage of each circuit are monitored through current and voltage transmitters to real-time grasp the distribution of distribution load and avoid circuit overload (such as when the air conditioning on a certain floor of the office building is started centrally, causing excessive current, the transmitter can trigger air switch protection).

Electricity metering and statisticsCooperate with active power transmitters and reactive power transmitters to calculate the electricity consumption (active energy) and reactive losses of a certain area or equipment, providing data for power cost accounting and power factor compensation (such as factories needing to configure capacitor compensation cabinets based on reactive power data to improve grid efficiency).

Power grid quality monitoringMonitor the fluctuation and harmonic content of AC voltage (requiring a dedicated harmonic transmitter), determine whether the power grid is stable, and avoid precision equipment (such as PLC and sensors) failures caused by unstable voltage.

3、 Energy management and energy-saving renovation

rail transitMonitor the AC voltage and current of the overhead contact system in the traction power supply system of subways and high-speed trains to ensure stable power supply for trains; Simultaneously monitor the electrical parameters of the ventilation and lighting systems within the station to ensure operational safety.

Charging station systemIn electric vehicle charging stations, AC current and voltage transmitters are used to monitor the power parameters during the charging process, control the charging power, avoid overload, and measure the amount of charging electricity (converted into cost).

municipal facilitiesIn municipal systems such as streetlights and pump stations, monitor the circuit current to determine if the equipment is operating properly (if the streetlight current on a certain road section is zero, it may be due to a line fault or damaged lighting fixtures, and remotely alarm through transmitter data).
