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, if necessary,
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:
Phase to Phase Voltage MOV Conduction Current
320Vac (RMS) 0A
620V maximum clamping 1mA (DC test current)
810Vpeak 100A peak
