The Desco 04623 Trustat Bench Top Ionizer is a compact (8.5" high x 6.0" wide x 2.6" deep) ionizer used for neutralizing electrostatic charges on insulators and ungrounded conductors in a 12" x 24" coverage area. Its discharge times (< 2 seconds at 12") and ±25 Volt offset voltage meet the required limits of ANSI/ESD S20.20 and ESD TR53. The Desco 04623 Trustat Bench Top Ionizer operates on pulse DC. Pulse 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. The two polarities alternately pulse on and off to limit ion recombination. The ionizer’s one speed fan (77 CFM) produces consistent performance within the coverage area. The Trustat Bench Top Ionizer features a powder coated steel enclosure.
