Dosing Pump System Upgrade｜ARF240 Breaks Power Density & EMC Limits

Dosing Pump System Upgrade｜ARF240 Breaks Power Density & EMC Limits

In precision industrial applications such as chemical dosing, water treatment, and process control, dosing pumps are the preferred choice thanks to their high accuracy, low maintenance, and easy integration. This case study comes from a European renowned customer, who faced the following design challenges when developing their next-generation dosing pump control module:

  • Limited space requiring a compact, high power density power supply
  • Strict EMC compliance requirements
  • Urgent project timeline requiring rapid system integration with certified components
  • High operating ambient temperatures

To address these challenges, the customer selected the ARCH ARF240 series AC-DC switching power module, which successfully overcame the design bottlenecks and accelerated the product development and launch timeline.

☑ Application Background: What is a Dosing Pump?

Dosing pumps, typically peristaltic pumps, are widely used for:

  • Injecting disinfectants (e.g., chlorine)
  • Metering corrosive or high-viscosity chemicals in industrial processes
  • Precision dosing in food and process industries where accuracy is critical

Due to their precise operation, valve-free structure, and modular maintenance, dosing pump systems place high demands on power supplies in terms of stability, EMI resilience, and space optimization.

☑ Why Choose the ARF240?

  • High Power Density in a Compact Form Factor

    The ARF240 features a compact form factor, delivering up to 240W output under natural convection cooling. It saves valuable PCB space within control modules without compromising performance.

  • Outstanding EMC Performance

    With built-in filtering and protection circuitry, the ARF240 meets EN55032 Class B standards, ensuring stable operation of sensitive pump control systems and minimizing EMI-related failures.

  • Wide Operating Temperature Range for Harsh Environments

    The ARF240 supports an extended operating temperature range of -40°C to +80°C, making it suitable for high-temperature or enclosed environments while reducing the risk of thermal shutdowns.

  • CB Certified for Fast Integration

    Certified to IEC 62368-1 and CB standards, the ARF240 helps customers reduce testing time and simplify global regulatory approval, enabling faster time-to-market.

☑ Project Results

By integrating the ARF240, the customer successfully achieved the following:

  • Saved valuable installation space within the dosing pump system
  • Passed stringent EMC tests, enhancing overall system reliability
  • Accelerated system integration and met the target product delivery schedule

☑ Conclusion: ARF240 Empowers Next-Gen Precision Control Systems

As chemical dosing and automation applications evolve, the demands on power supplies increase. With its compact size, high reliability, and excellent EMC compatibility, the ARF240 is the ideal power solution for next-generation precision industrial systems.
