The power supply output is limited to 5mA (UL62368-1 requirement) therefore the number of bars is dependent on several factors, including bar length, cable length, power supply output voltage (kV), distance from the bar to ground etc…
For more guidance, please contact your local Meech distributor or contact Meech directly.
For quick reference to see if your AC static control system is working, the local LED on the anti-static bar should illuminate green. Furthermore, the LED on the power unit will show green when functioning properly and will go red when there is a fault.
To verify the operation of both AC and DC powered static eliminator bars, Meech have developed the 984v2 Ion Sensor for inspection.
A sensor in the end panel of the 984v2 detects ions given off by the emitter pins of an ionising bar. The performance of the bar can then be verified by the distance at which the indicator lights of the 984v2 operate. The closer the 984 is required to be held to the ioniser, the weaker the field caused by the contamination on the ionising bar. Repeated measurements over a number of months will give an indication of when the static eliminator bar requires cleaning.
Yes, with a high voltage probe connected to a standard multimeter it can be used to measure the high voltage energy on the emitter pins. Direct connection of a multimeter will damage the meter. We would recommend the 984v2 Ion Sensor to test all static control equipment is functioning properly.
Exposure to Ozone (O₃) caused by high voltage will attack materials. The insulative properties of the AC cable will weaken over time to eventually fail and create a short circuit and ioniser failure. DC bars are less susceptible to cable failure.
It is not advised for AC anti-static bars to be installed in a moving location. The high voltage AC cable and conduit is not designed to handle constant movement. However, the DC range does possess this ability.
We would recommend ordering the bar with the correct cable length. Preventing high voltage short circuits and potential shocks to operators restricts the ability from extending cables.
