Ⅰ. Introduction
One-way power supply surge protection device is designed, manufactured, and tested in compliance with international standard IEC61643, Chinanational standard GB18802.1, meteorological standard QX10.1-2002, and communications standard YD/T1235.1-2002. And quality control of our product is in strict accordance with ISO9001.
It’s adopted in various kinds of low voltage AC/DC devices like communications devices, speakers, video devices, surveillance system, precision meters, andLED streetlamps. It can prevent the devices from being damaged by induced over voltage and surge over current of the lightning strike.
