Theory of Operation
By definition, materials that are insulators cannot have static
charges removed via grounding as they do not conduct
electricity. Ionizer emitters flood an area with millions of
positive and negative charged electrons to neutralize insulators
that have static charges on them.
The Chargebuster Jr. employs a safe non-nuclear
Steady-State DC ionization source. Steady D.C. 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 ionizer’s unique, closed
loop monitoring circuitry monitors ion output and automatically
adjusts the unit to reach an equilibrium at perfectly balanced
ion flow. The ionizer is designed to achieve balance under
extreme conditions and is uniquely able to maintain balance in
almost any environment. Desco ionizers meet the ANSI/ESD
S20.20 minimum recommended technical requirement range
of less than ±50 volts voltage offset tested in accordance
with ANSI EOS/ESD S3.1. Chargebuster Jr. Ionizers greatly
exceed the requirement providing as low as ±5 volt auto
balancing.
The unit’s circuitry also features a visual and audible ‘CHECK
IONIZER’ alarm, which alerts the user to abnormal conditions
caused by excessive electrode contamination or the failure
of either the positive or negative power supply. When the
Chargebuster Jr. is ON and operating normally, the blue LED
indicator on the front of the unit will be steadily lit. ‘CHECK
IONIZER’ is indicated when the blue LED is flashing. See
the maintenance section for recommended maintenance
procedures. This feature safeguards that the ionization is
balanced, protecting sensitive components and assemblies
from being exposed to harmful charging from an out of balance
ionizer.
The Chargebuster Jr.’s quiet and gentle fan is designed so
that it will not disturb personnel, paperwork, or delicate parts.
The LED indicator mounted on the face of the unit allows the
operator to easily verify whether it is ON, OFF, or in need of
maintenance. The ionizer’s emitter electrode material will not
require replacement during the normal life of the product.
The Chargebuster Jr. is engineered for efficiency and
durability. The unit’s automatic feedback balancing circuitry
eliminates the need for repeated calibration, making this
ionizer highly dependable and cost effective.

Testing and Calibration
We recommend annual calibration of our ionizers. Ionizers
are tested and calibrated using a charged plate analyzer. For
proper testing, we recommend a charged plate analyzer and
the procedure outlined in ESD Standard S3.1. This standard
may be purchased from the ESD Association, 7902 Turin Rd.,
Suite 4, Rome NY 13440-2069, (315-339-6937). If you have
access to a charged plate analyzer, you can use it to calibrate
the Chargebuster Jr. We will be happy to send you information
on the EMIT model
50555 Charged Plate Analyzer.
Desco’s 1 year limited warranty (see conditions below) may
be voided if calibration is attempted within the first year of use
of the product. Calibration traceable to National Institute of
Standards and Technology (NIST) is a standard feature of all
Models.
