How to detect the performance of ion blowers
How to detect the performance of ion blowers? Ion blowers have a balance voltage, which can be measured using ion blower testers such as: ME-268A-1, CPM374, EFM022 electrostatic field tester/CPS022 test kit, etc. The balance voltage is a very important performance of ion blowers! It reflects the electrostatic hazard that the ion blower will bring to the object it acts on when it is working, that is, the static voltage generated on this object. If this voltage does not exceed the anti-static ability of the ESD sensitive device, it is safe. The current balance voltage of ion blowers can be only a few volts, so it is safe for most cases.
The static electricity on the charged body is not enough to neutralize the static electricity generated by the ion blower! That is to say, the static electricity on the charged body is completely neutralized by the ion blower. After that, the positive and negative ions produced by the ion blower 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 blower and a pulsed DC ion blower, the frequency of alternating positive and negative ions is 60hz, which can also be considered to act at the same time). At this time, the object will not carry static electricity. There will be no voltage that causes damage to sensitive devices.
Of course, it is not an absolute 0V at this time. There should be a relatively low voltage on the object, and this value should be less than the balance voltage. It is safe within an acceptable range! Therefore, when choosing an ion blower, the balance voltage is a very important consideration.
