The Meech 906 power unit was designed to comply with UL requirements for ES2 energy sources. To achieve this, the output has software and hardware protection to limit the output current to 5mA maximum.
To stay within these safety limits and operate the ionisers at full efficiency, the maximum combined lengths of attached ionising bars and cables can be calculated using the guide found on the Meech SharePoint site called “906 Power Supply – Bar and Cable Length Guide.pdf’.

For quick reference to see if your AC static control system is working, the local LED on 906 power unit that powers the AC ionisers should illuminate green to indicate normal operation.
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.
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.
