RE: AC Current to Voltage Transducer

["Dave McLaughlin" <dave@xxxxxxx>]

Hi Christian,

 

You do realise that the the +-15V is the supply to the device, ie you will need to supply it with +15V and -15V of DC power with the GND being the common for both the supply and output signal.

 

You can easily build a +-15V supply with very basic components, but you would be quicker to pickup a surplus switch mode power supply with the required outputs. Check out www.greenweld.co.uk for some really low cost units.

 

Regards

Dave...

Hi

 

I need help, I brought the LEM Current Transducer as recommended by the group - Thanks.

 

However wiring help please. It has +15 volts, - 15 volts, output and 0 volts.

 

I am currently not getting anything out of it, can anyone help?
