Enhanced lightning surge resistance doubled! An example of implementation by a communication equipment manufacturer that achieved zero equipment failures due to lightning by protecting outdoor communication devices with custom power supplies.

Outdoor communication equipment is constantly exposed to the risk of failure from lightning surges, which may lead to service outages and decreased customer satisfaction. This article introduces a case study of an enhanced power solution provided by UNIFIVE to supplement the insufficient resistance of standard adapters. The solution achieved zero lightning-related failures even in real-world testing, contributing to improved operating rates and reduced maintenance costs.

“Worried about service outages from lightning damage to communication devices?”

Outdoor communication equipment is constantly exposed to the risk of lightning.

“We want to use power for outdoor communication devices, but we're concerned that a lightning surge might damage our equipment.” We received this type of inquiry from a communications device manufacturer. In environments especially vulnerable to lightning surges, such as base stations, standard AC/DC Power Adapters — Desktop & Wall-Mount alone do not offer sufficient protection.

This time, we will introduce a case study where communication reliability was secured using a custom power supply with enhanced lightning surge protection.

Customer Challenges and Background

Standard AC/DC Power Adapters — Desktop & Wall-Mount had insufficient surge protection, increasing the risk of equipment failure during lightning strikes

- Service interruptions due to lightning could lead to decreased customer satisfaction

- Outdoor installation required that maintenance frequency be kept to a minimum

Step	Strategy	Effect
1	In-depth surge resistance hearing and environmental analysis	Set optimal protection level
2	Adopted surge absorbers + enhanced insulation design	Achieved double the surge resistance of standard products
3	Tested under high voltage conditions simulating real environment	Capable of withstanding surges beyond initial expectations

[Key Point] Surge protection fully reinforced with power supply only, no changes to existing device design!

Post-Implementation Results

1. Field testing showed zero equipment failures from lightning

2. Improved operational uptime led to higher customer satisfaction

3. Reduced maintenance frequency resulted in lower operating costs

Customer Feedback

“Even during real-world field tests, not a single failure occurred due to lightning. Now we can confidently deliver our Products even in areas with frequent thunderstorms!”
