What method is used to prove the performance of ion fan
Ion blowers have a balanced voltage, which can be measured with ion blower testers such as ME-268A-1, CPM374, EFM022 electrostatic field tester/CPS022 test suite, etc. Balance voltage is a very important performance of ion fans! It reflects the electrostatic hazard that the ion fan will bring to the object when it is working, that is, the static voltage that will be generated on the object. If this voltage does not exceed the antistatic ability of the ESD sensitive device, it is safe. The balance voltage of the current ion fan can be only a few volts, so it is safe for most situations.
The static electricity on the charged body is not enough to neutralize the static electricity generated by the ion fan! That is to say, the static electricity on the charged body is completely neutralized by the ion fan. After that, the positive and negative ions produced by the ion fan should be relatively balanced (the balance voltage is not considered, because this voltage is safe for the product), Relatively speaking, the positive and negative ions act on the object at the same time (even if it is an AC ion fan and a pulsed DC ion fan, the alternating frequency of the positive and negative ions is 60hz, which can also be considered to be simultaneous), then the object will not be charged with static electricity. There will be no voltage that can cause damage to sensitive devices.
Of course, this is not a good 0V, there should be a relatively low voltage on the object, this value should be less than the balance voltage. It is safe within an acceptable range! Therefore, when choosing an ion fan, the balance voltage is a very important consideration.
