How to detect the performance of the ion fan
How to detect the performance of the ion fan? The ion fan has a balanced voltage that can be measured using an ion blower tester such as ME-268A-1, CPM374, EFM022 electrostatic field tester/CPS022 test kit. Balanced voltage is a very important feature of ion fans! It reflects the electrostatic hazard that the ion blower will bring to its active object, that is, the static voltage that will be generated on this object. If this voltage does not exceed the antistatic capability of ESD sensitive devices, it is safe. Current ion fans have a balanced voltage of only a few volts and are therefore 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 (regardless of the balance voltage, because this voltage is safe for the product), Relatively speaking, positive and negative ions act on the object at the same time (even if the AC ion fan and the pulsed DC ion fan, the frequency of alternating positive and negative ions is 60hz, it can be considered as simultaneous action), and the object will not be charged with static electricity. There is no voltage that can cause damage to sensitive devices.
Of course, this time is not an absolute 0V, there should be a relatively low voltage on the object, this value should be less than the balance voltage. In an acceptable range, it is safe! Therefore, when choosing an ion fan, balancing the voltage is an important consideration.
