AC Surge Protective Device SPD Surge Protection Device


Surge Protective Devices are designed to protect against transient surge conditions. Large single surge events, such as lightning, can reach hundreds of thousands of volts and can cause immediate or intermittent equipment failure. However, lightning and utility power anomalies only account for 20% of transient surges. The remaining 80% of surge activity is produced internally. Although these surges may be smaller in magnitude, they occur more frequently and with continuous exposure can degrade sensitive electronic equipment within the facility.

We have a comprehensive line of surge protection devices to meet your needs, regardless of the exposure risk. They help reduce costly downtime and protect sensitive electronic equipment against the damaging effects of transients caused by lightning surge current, utility switching, internal load switching and more. Each unit is independently tested and backed by the largest engineering and technical support in the industry.

We are a real AC&DC surge protection device (SPD) manufacturer, also provide OEM/ODM service. some of the products approved by TUV, CB, CE, EAC according to IEC 61643-11:2011 and EN 61643-11:2012.
