The 650QAC bar includes a Total Ion Current Control technology (TICC) to measure net ion current and make automatic adjustments to the bars parameter to maintain a low offset voltage (<35V).
TICC is designed to continually adjust the offset voltage holding it within the desired limits, protecting voltage sensitive components.
The 650QAC is positioned differently, uses different technology and serves a specific function. Without listing the features and benefits QAC is a ‘focused solution’ dedicated to the electronics sector which demands very low and stable offset voltage – typically between +/- 35v.
Whilst the 924IPS bar offers excellent performance in reducing charge voltages at short range, and in some circumstances when settings are refined, they can result in very low off set voltages but in general they will not offer the same low voltage consistently.
Yes, industry experts suggest that anything from 8-33% of electronic failure is down to ESD! With the addition of QAC it is expected that failure or worse latent defects will be reduced, resulting in higher yields and greater profits.
Yes, QAC comes with automatic distance presets for a quick and easy set up. Requires no need for plug in handsets or charge plates, it is an out the box fully optimised solution.
ESD stands for Electrostatic discharge and is the release of static electricity between two electrically charged objects when they are brought close together and can often be seen as a visible spark. An electrostatic discharge can not only give shocks to operators, but it can also result in considerable damage within a production environment.
Yes, the emitter pins on the 650QAC are replaceable. To ensure a safe replacement please use a Meech emitter key to remove and replace pins, all Meech emitter kits will be sent with an emitter key.
When the bar is >150mm away from the target the air assist can be used to maintain low decay times and consistently low operating voltages. To connect the air supply there is a 6mm push-fit airline fitting at the end of the bar. The compressed air supply should be filtered and limited to a maximum of 2 bar (29PSI).
The lights on the QAC change to act as visual indicators when adjusting the bar. When the central LED is lit, the Balance is being held at the set-point. LED’s to the left indicate a Negative balance. LEDs to the right indicate a Positive balance.
