With the deepening of the national industrialization, informationization, urbanization and agricultural modernization strategy, the strategic emerging industries will show a good momentum of development, a wide range of information and communication technology industry penetration and leading role will be further enhanced.
Innovative and Advanced CS Series Gas Mass Flow Controllers Flowmeters are a device that can accurately measure and control a wide range of medium and small flow gas mass flows. The product has high precision, fast response, good sealing, corrosion resistance, low zero drift and temperature drift, easy to use and so on.
Alone, the difference between the level of water can not maintain a steady flow of water, and by means of continuous water pump from the low to be able to maintain a certain level of water to form a steady flow of water. Similarly, the electrostatic field generated by the charge alone can not maintain a steady current, and by means of a DC power supply, the non-electrostatic effect (referred to as "non-electrostatic force") can be used to make the positive charge from the lower potential Through the internal power back to the higher potential of the positive pole, in order to maintain the potential difference between the two electrodes, resulting in a steady current.
Each electronic device has a power supply circuit that supplies energy. The power supply circuit has three kinds of rectifier power supply, inverter power supply and frequency converter. Most common household appliances use DC power supplies.
