A leading provider of wireless control solutions for industrial automation required compact, reliable power supplies to support their robust transmitter and receiver modules. Their systems operate in challenging industrial environments—where stable operation, protection from electrical noise, and flexibility in board layout are essential for safety and uptime.
Key design goals included:
- Wide input range and high efficiency to accommodate variable field power sources
- Strong electrical isolation and protection for sensitive signal circuits
- Compact footprints to maintain tight, modular board layouts
- Integrated short-circuit and over-voltage protection
To address these requirements, the engineering team selected three DC/DC converter families from MicroPower Direct: the MB3000BRU, providing 30W output, an ultrawide 4:1 input range, and 1,500 VDC isolation in a compact case; the MSR7810MW, a 1A switching regulator with a wide input range, tight regulation, and LM78xx pin compatibility; and the LF100BI, a 1W ultra-miniature SMT DC/DC with 3,000 VDC isolation and short-circuit protection, ideal for dense, multi-channel modules.
By integrating these modules, the customer ensured stable, low-noise power distribution across their wireless control platforms—delivering consistent performance, streamlined design, and improved system protection in demanding industrial environments.
