Pulse AC method for faster charge removal
The ER-X series has adopted the pulse AC method
that alternately applies positive and negative voltages
to each discharge needle. This enables generation and
discharge of a large amount of ions, resulting in faster
charge removal. Select from eight pulse frequencies
according to your application, from 100 Hz for charge
removal on nearby or moving workpieces to 1 Hz for
charge removal on far-away workpieces or in a three-
dimensional space.

Automatic ion balance control
The ER-X series provides an automatic ion balance
control mechanism that senses the amount of ions being
generated (which changes according to environmental
factors) and compensate for this deviation in the
controller, thus maintaining a highly stable ion balance
as an original operator setting.

The pulse AC method enables the ER-X001 to generate
and discharge a large amount of ions, which makes
charge removal faster. Furthermore, as a spot type
ionizer, it achieves the fastest charge removal of 0.3 sec.
