The SCS 770122 Benchtop AC Ionizer is used for neutralizing electrostatic charges on insulators and ungrounded conductors. Its discharge times (< 2 second at 12 inches) and ±15 volt offset voltage exceed the required limits of ANSI/ESD S20.20 and ESD TR53. The 770122 Benchtop AC Ionizer generates AC high voltage to produce an airflow rich in positive and negative ions. A built-in automatic emitter point cleaner periodically brushes away dust and minimizes maintenance. Membrane switches are located at the top of the ionizer to control power, fan speed, and emitter cleaning. The 770122 Benchtop AC Ionizer features a powder coated steel enclosure and stand and a 24 VDC alarm output terminal.

Ionizers are useful in preventing electrostatic charge generation, electrostatic discharge, electrostatic attraction, as well as preventing equipment latch-up. Per ANSI/ESD S20.20 section 6.2.3.1. Protected Areas Requirement states: "Ionization or other charge mitigating techniques shall be used at the workstation to neutralize electrostatic fields on all process essential insulators if the electrostatic field is considered a threat.” “Air ionization can neutralize the static charge on insulated and isolated objects by producing separate charges in the molecules of the gases of the surrounding air. When an electrostatic charge is present on objects in the work environment, it will be neutralized by attracting opposite polarity charges from the ionized air. Note that ionization systems should not be used as a primary means of charge control on conductors or people." (Reference: EN 61340-5-2:1 clause 5.2.9)
