Dear Sir,

Thank you for your interest in our product lines. Currently, we do not list the transient protection in our catalog specifications. I can check with our Engineers about adding the specification if it is absolutely necessary?

Hi...i am a new user here.I use an old ac-output wall-wart transformer for this purpose. These are a dime-a-dozen at garage sales around here. I have even broken off the plastic case and used just the transformer to get rid of the rectifier in a DC output wall-wart.Lightly loaded by just a measuring circuit, these make an ideal line-voltage measuring method. If you are going into a micro ADC, you can put an opamp precision full-wave rectifier between the low-voltage secondary and the ADC input.
