Description
The SCS Ion Pro™ Benchtop Ionizer is used for neutralizing electrostatic charges on insulators and ungrounded conductors. Its fast discharge times (< 1.5 seconds at 12 inches) and ±3 volt offset voltage exceed the required limits of ANSI/ESD S20.20 and ESD TR53. The Ion Pro Benchtop Ionizer monitors both its offset voltage (balance) and discharge time. The ionizer will alarm should its offset voltage exceed the required limits defined by ANSI/ESD S20.20 or discharge time take longer than 4.5 seconds. Steady-state DC emitters are spaced farther apart to prevent ion recombination, increase decay efficiency, and provide a broader coverage area of ionization. The Ion Pro™ Benchtop Ionizer’s dual-speed fan produces consistent airflow performance. The Ion Pro™ Benchtop Ionizer features a stainless steel enclosure and multi-mount stand to minimize contamination and corrosion when used in clean or sensitive areas.
The SCS Ion Pro™ Benchtop Ionizer operates on Steady-state DC. Steady-state DC systems consist of separate negative and positive ion emitters connected by a pair of high-voltage cables to their respective high-voltage power supplies. DC power is constantly applied to the emitter points. The ionizer utilizes patented capacitance-based sampling from its internal sensor to continuously adjust the output, maintain its offset voltage, and minimize maintenance.
“The primary method of static charge control is direct connection to ground for conductors, static dissipative materials, and personnel. A complete static control program must also deal with isolated conductors that cannot be grounded, insulating materials (e.g., most common plastics), and moving personnel who cannot use wrist or heel straps or ESD control flooring and footwear. Air ionization is not a replacement for grounding methods. It is one component of a complete static control program. Ionizers are used when it is not possible to properly ground everything and as backup to other static control methods. In clean rooms, air ionization may be one of the few methods of static control available.” [ESD Handbook ESD TR20.20 Ionization, section 5.3.6.1 Introduction and Purpose / General Information]
