Silicon Avalanche Diode AC surge suppression

The manufacturing facility was founded in 1985. The company focuses on designing innovative products and provides superb customer service and unparalleled technical support. This combination has positioned our plant as the “largest single source power protection supplier in the world”.

Northern Technologies successfully combines non degradable, bipolar Silicon Avalanche Diode (SAD) technology for primary protection and Metal Oxide Varistor’s (MOV) as back up to protection for sensitive digital equipment during lightning strikes or power transients.

AC power protection equipment offered is modular, field repairable and includes an “unconditional ‘act of nature’ three-year warranty” against any and all damages. This results in downtime that is significantly decreased and equipment life that is seriously extended.

By choosing to do business with Northern Technologies SA you gain access to more than 70 years of combined experience in the lightning and surge suppression industry.

Class 1 Lightning Arresters

Our Eastern European facility was founded in 1989, its main activity is the production of transient voltage protection devices in the field of low voltage power supply networks.

Our Class 1 metal oxide varistor products are of particular significance, because we have developed a range of products which provide fast acting, modular devices with high energy capabilities. These are using semiconductor material as opposed to the antiquated air or spark gap technology. Northern Technologies now supplies a complete solution, which combines high energy lightning protection with fast acting surge suppression.

All surge and lightning protection offered by Northern Technologies are manufactured to the highest possible standards and comply with the IEC, VDE, OVE, UL, and ISO 9000.
