A manufacturer of industrial control systems needed a compact, reliable power solution for instrumentation modules such as signal conditioners and transmitters. Designed for use in control panels and process environments, these systems demanded stable, isolated power to protect sensitive electronics from electrical noise and maintain long-term performance.
Key Design Goals:
- Wide 4:1 input voltage range for flexible system integration
- 3,000 VDC isolation to protect sensitive electronics
- Compact DIP footprint for dense layouts
- Continuous short-circuit protection for reliability
To meet these needs, the engineering team selected the MA300RUI family from MPD. This 3W converter features single and dual outputs, robust isolation, and operates over a broad temperature range (–40°C to +85°C). Its industry-standard DIP package and UL 62368 approval ensure safe, efficient power delivery in demanding environments.
By integrating the MA300RUI, the customer achieved long-term reliability and consistent performance for their critical instrumentation—supporting robust industrial control and measurement across their entire product line.
