There seems to be only limited technical information about this device. The pdf has various parameters on it but no application data, nor any information on how and what to collect it to. I.e driving voltage 20 Vrms, 20 V of what?

Asked by: TonyM
The item is a component part the implementation of if in a circuit or project is up to you, we do not provide any advice on how to use component parts in projects.
