AC Surge Protection: It is important that ac surges reaching rectifiers do not exceed the capacity of the rectifier
internal surge protection. Protection must be provided external to the GPS system to limit surge energy reaching
the rectifiers. Site surge protection must be coordinated with rectifier internal surge protection and must clamp at
a lower voltage than the rectifier internal protection. The internal protection voltage and current characteristics of
the rectifiers are as follows:
