Current sensor is a kind of detection device, which can sense the information of the measured current and transform the detected information into electrical signal or other information output according to certain rules to meet the requirements of transmission, processing, storage, display, recording and control of information.
Current sensors, also known as magnetic sensors, can be used in household appliances, smart grids, electric vehicles, wind power generation and so on. Many magnetic sensors are used in our lives, such as computer hard disk, compass, household appliances and so on.
Current sensor is an active module, such as Hall device, operational amplifier, terminal power transistor, which needs working power supply and power consumption.
1. The output terminal is connected with large electrolysis to reduce noise.
2. Capacitance potential uF, diode 1N4004;
3. Transformers depend on the power consumption of sensors.
4. The working current of the sensor. Direct-check (no amplification) power consumption: maximum 5mA; direct-check amplification power consumption: maximum (+20mA); magnetic compensation power consumption: 20 output current; maximum consumption of 20 output current twice. The power consumption can be calculated according to the consumption of working current.
