Surge Protection
by Industry
Complete SPD and lightning protection systems for six industries — from utility-scale solar to medical device OEM manufacturing. Find your application below.
Solar PV & Energy Storage
A lightning strike on an unprotected PV string can destroy a $100K+ inverter in under one millisecond. DC arcs do not self-extinguish — standard AC protection is not enough. IEC 61643-31 DC SPDs, AC grid tie-in protection and site LPS for every installation scale.

Protecting the AC feed while leaving RS485 signal lines exposed still destroys the PLC — surges enter through field sensor cables and bypass power protection entirely. DIN-rail AC SPDs and RS485 signal protectors for control panels, SCADA systems and panel builders.
View Industrial Protection →EV Charging Infrastructure
EV charging stations are installed outdoors permanently — one storm can take an entire charging plaza offline. AC SPD for distribution boards, network SPD for payment terminals and 4G lines, site LPS for high-exposure installations.
View EV Charging Protection →Data Center & Telecom
One surge on the AC supply, network lines or -48V DC bus can consume your entire annual downtime budget in seconds. AC SPDs for UPS and main boards, network SPDs for server racks, purpose-built -48V DC SPDs for telecom base stations.
View Data Center Protection →Commercial & Industrial Buildings
A building that passes inspection needs all three IEC 62305 protection zones — not just a single SPD at the main board. ESE lightning rods, grounding systems, and coordinated Type 1/2/3 SPDs for EPC contractors and facility managers.
View Building Protection →Medical Equipment OEM
Standard industrial SPDs clamp at voltages far too high for sensitive analog circuits operating at 5V–48V — the SPD stays dormant while the circuit is destroyed. Type 3 low clamping SPDs and signal line protection for medical device OEM manufacturers.
