20x improvement in lightning surge resistance! A case study of a telecommunications equipment manufacturer that achieved zero equipment failures from lightning strikes with a custom power supply that protects outdoor communication devices
Outdoor communication equipment constantly faces the risk of failure due to lightning surges, which can lead to service outages and reduced customer satisfaction. This article introduces a case study of the reinforced power supply solution provided by UNIFIVE to compensate for the insufficient durability of standard adapters. Even in real-world environment testing, zero failures caused by lightning were achieved, contributing to improved operational uptime and reduced maintenance costs.

"Communication equipment damaged by lightning... We absolutely want to avoid service outages" Are you facing this issue?
Outdoor communication equipment is constantly exposed to the risk of lightning strikes.
"We want to power outdoor communication devices, but we are concerned that surge currents during lightning strikes may damage the equipment." We received this type of inquiry from a communication equipment manufacturer. Especially in environments such as base stations that are highly susceptible to lightning surges, standard AC/DC Power Adapter may not provide sufficient equipment protection.
This time, we introduce a case study where reliability of communication equipment was ensured with a custom power supply enhanced for lightning surge resistance.
Customer Challenges and Background
Standard AC/DC Power Adapter had insufficient surge resistance, resulting in a high risk of equipment failure during lightning strikes.
- Risk of decreased customer satisfaction due to service outages caused by lightning
- Desire to minimize maintenance frequency due to outdoor installation
| Step | Measure | Effect |
|---|---|---|
| 1 | Detailed hearing of surge tolerance requirements and environmental condition analysis | Optimal protection level established |
| 2 | Adopted surge absorber + reinforced insulation design | Achieved 20 times the surge resistance of standard products |
| 3 | Verified through high-voltage testing simulating real environments | Capable of handling surges exceeding expectations |
[Key Point] Fully strengthened lightning surge protection using only the power supply, without changing the existing equipment design!
Results After Implementation
1. Achieved zero equipment failures caused by lightning in field tests
2. Improved operational uptime of communication services, increasing customer satisfaction
3. Reduced maintenance frequency, lowering running costs
Customer Feedback
"In actual field tests, not a single failure due to lightning occurred. We can now confidently provide Products even in regions with frequent thunderstorms!"
