Ff-352 capacitance parameters

15 kV or more. FF-352 is a high-voltage negative ion generator produced by Ningbo Ge Xiang Electric Appliance Co., Ltd. Usually, the wire connected to mica frame is a high-voltage discharge needle above 15 kV, and black and red are power input wires. The negative ion generator is a device that generates negative ions in the air. After the input DC or AC is processed by EMI processing circuit and lightning protection circuit, the pulse circuit will overvoltage and limit the current. The high and low voltage isolation wires are upgraded to AC high voltage, and then the pure DC negative voltage is obtained after rectification and filtering by special electronic materials. A negative DC voltage is connected to a release tip made of metal or carbon, and a large number of electrons (e-) are released at a high speed by using a high DC voltage at the tip. However, electrons can't exist in the air for a long time (the existing electron lifetime is only ns), and they will be immediately captured by oxygen molecules (O2) in the air, thus generating air negative ions. Experimental research shows that ecological negative oxygen ions with smaller particle size can penetrate the blood-brain barrier of human body more easily and play a role in medical care.
