People Counting in Demanding Environments: Reliable Power for Accurate Vision

 

 

Premium PSU continues to invest in specialized power electronics for embedded AI, smart counting, and vision systems in transport. The CLS-120 is a clear example of how robust power design can make the difference in projects where precision, integration, and reliability are critical.

Power electronics enabling the future of smart mobility

With the growing automation of public transport and railway networks, embedded AI applications are becoming standard. In this context, Premium PSU, in collaboration with its partner Relec (Martin Bull, Business Development Manager), worked with a transport technology provider to deliver a reliable people counting solution in a high-traffic environment.

One of the main challenges was the lack of an efficient inverter that could precisely control the speed of the motorized fans, avoiding current surges during startup and ensuring more stable operation.

The Challenge: Clean, Stable Power for AI Vision in Harsh Conditions

The goal was clear: to provide stable and safe power to embedded vision sensors with non-standard DC input, capable of operating in an environment filled with:

  • Electrical noise
  • Constant vibrations
  • Fluctuating temperatures

People counting systems must function flawlessly, even when thousands of passengers pass through in just a few minutes. For accurate and consistent performance, these sensors require a power solution that is:

  • Compact and easy to integrate
  • Highly immune to electromagnetic interference (EMI)
  • Capable of converting non-standard voltages
  • Protected against overloads and network disturbances

The Solution: Premium PSU’s CLS-120 converter

The CLS-120 was the ideal fit — a robust DC/DC converter designed for harsh transport environments. Its key features include:

  • Wide non-standard input range, compatible with diverse system architectures

  • Stabilized output to protect sensitive AI hardware

  • High EMI immunity and integrated noise filtering

  • Compact form factor, ideal for embedded or cabin integration

  • Full compliance with major railway and transport standards

Real-world application: AI-based counting at an international airport and railway stations.

This solution was deployed in critical high-flow passenger areas — including a major European international airport and busy railway stations — where the environment posed multiple challenges:

  • Continuous heavy passenger traffic
  • Potential micro-cuts or power fluctuations
  • Limited space for additional equipment

Despite these conditions, the CLS-120 enabled the embedded vision system to operate with over 98% counting accuracy, even during peak hours.

Expert Insight

“Adapting the power supply to such a constrained environment — like a train carriage — was a real challenge. We needed highly robust electronics: immune to noise, yet compact and easily integrable. After several validation rounds, the CLS-120 helped us deliver a tested, proven solution in just a few weeks.”
— Francisco Mauro, Project Manager, Premium PSU

Customer Feedback

“Integrating the CLS-120 into our embedded counting system fully resolved the electrical noise issues we had been experiencing in high-traffic environments. The converter delivered a stable response to transient spikes and integrated seamlessly into our architecture — with no compromise in space or performance.”

A Reliable solution for smart transport

Premium PSU continues to invest in specialized power electronics for embedded AI, smart counting, and vision systems in transport. The CLS-120 is a clear example of how robust power design can make the difference in projects where precision, integration, and reliability are critical.

Broader application scope: Beyond Airports and Railways

While this case focused on a high-traffic transport environment, the CLS-120 converter is equally suited to other demanding sectors where embedded vision systems are critical. From maritime transport (ferries and cruise ships) requiring robust, vibration-resistant power supplies, to smart infrastructure such as stadiums, metro stations, and large public venues, the need for stable DC power is universal. Additionally, industries like retail analytics, building automation, and healthcare facilities increasingly deploy AI-powered people counting and monitoring systems. In each of these contexts, the CLS-120 provides compact, EMI-immune, and highly reliable power — making it a versatile solution wherever accuracy, uptime, and safety are non-negotiable.
