20x Improved Lightning Surge Resistance! A Case Study of a Telecommunications Equipment Manufacturer That Achieved Zero Equipment Failures from Lightning Strikes with Custom Power Supplies Protecting Outdoor Communication Devices

Outdoor communication equipment is constantly exposed to the risk of failure caused by lightning surges, which can lead to service outages and decreased customer satisfaction. This article introduces a case study of a reinforced power supply solution provided by UNIFIVE to compensate for the insufficient durability of standard adapters. Even in real-world environment testing, zero failures due to 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 challenge?

Communication equipment installed outdoors is constantly exposed to the risk of lightning strikes.

"We want to use a power supply for our outdoor communication devices, but we are concerned about equipment damage caused by surges during lightning strikes." We received this kind of inquiry from a communication equipment manufacturer. Especially in environments prone to lightning surges, such as base stations, 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 featuring enhanced lightning surge resistance.

Customer Challenges and Background

Standard AC/DC Power Adapter had insufficient surge resistance, increasing the 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 on surge tolerance 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-world environments	Capable of handling surges beyond initial assumptions

[Key Point] Fully enhanced lightning surge protection through the power supply alone, without changing the existing equipment design!

Results After Implementation

1. Achieved zero equipment failures due to lightning in field tests

2. Improved communication service uptime, increasing customer satisfaction

3. Reduced maintenance frequency, lowering running costs

Customer Feedback

"In actual field tests, not a single failure occurred due to lightning. Now we can confidently provide our Products even in regions with frequent thunderstorms!"
