Meech Pulsed DC Applications
Distance From Object
Originally Pulsed DC technology was developed for the electronics industry. Bars were
placed in laminar flow cabinets or above test benches. The distance from the object
was typically 1m.
For industrial applications the distance from the object is less - typically 150mm to
300mm. The rule for setting the frequency is that the closer the bar is to the object,
the faster the frequency setting.
Polarity
The polarity adjustment allows the output of the unit to be custom tuned to attack the
actual problem. If the charge is always strongly negative it makes sense to bias the
output towards a positive polarity, thus achieving faster neutralisation.
This requires a more sophisticated approach from the user. A Meech Model 983 Static
Locator becomes indispensable.
If the charge varies the output should be balanced in polarity.
