Pk between DC ion fan and AC ion fan
DC ion fans have been very popular recently, and it is natural to choose DC ion fans. The principle of the static eliminator is composed of a high-voltage power generator and a discharge electrode. The high-voltage corona discharge is used to ionize the air into a large amount of positive and negative ions to neutralize the static electricity on the surface of the object. It provides an ion eliminator with a wide range of concentrated areas that balance the flow of ions. The ion balance voltage is continuously adjustable and there is no feedback control circuit. The balance voltage can be stabilized at a very low position, eliminating or neutralizing the static charge of a wide range of concentrated targets or areas that are not easily accessible. It is an ideal static eliminator for precision electronic products, electronic assembly lines, pharmaceutical manufacturing assembly lines, printing, packaging and small products or molding.
The DC ion fan is discharged by two sets of electrodes. The speed of discharge per second is 220 volts and 24 kHz. It is characterized by large amount of ions, fast power-dissipation and good balance. The DC ion fan has a high safety factor, and the case current has a weak current of only 0.06 mA, which has no effect on the human body. In terms of materials, the needle of the DC ion fan is made of alloy material, the fan is imported, and the life can be continuously used for more than 50,000 hours. The internal structure of the DC has transformer and main control board (including frequency conversion circuit, rectification filter, amplifier circuit, etc.), Will be affected by voltage fluctuations, resulting in a decline in the life of the transformer.
The AC ion fan has only one set of electrodes to discharge. If it is 220 volts, the discharge rate is 50 Hz per second. If it is 110 volts, it is 60 Hz per second. Due to the alternating process of discharge, it is easy to cause the object to be reversed, and the power-off speed and balance are less than DC. The AC ion fan has a high induction current, the grounding system is not good, and it is easy to get an electric shock. Most of the materials used in AC ion blowers are made in China. The discharge needles are generally tungsten needles or stainless steel. The internal structure is mainly transformer. If the voltage fluctuation is too large, it will affect the service life of the transformer.
It is not difficult to see from the above that DC ion fan and AC ion fan have their own different advantages. I hope that when you purchase, you can choose which ion fan according to your own requirements.
