[?]: Voltage Transducer Protection

Post by Chrislari » Sat Apr 24, 2021 9:28 pm

Hello,

I am planning of using a Voltage Transducer to scale High Voltages 120V down to 0-10V.
By High Voltages mean voltage of 120V.
Any idea on how to protect the input side of the Voltage transducer against Overvoltage or Reverse polarity???

Thank you

Unipolar DC 120V ?
Diode bridge for Reverse polarity = -1V
Overvoltage ... use Transducer 200 to 1000 V
LEM Voltage Transducer

Thanks a lot for the response.
It is a signal voltage that will be manually connected. The case is if someone connects the the + and - reversed accidentally.
Do you have any particular diode in mind??
