Frequently Asked Questions

What input voltage protection is recommended?

For industrial applications, implement comprehensive input protection: TVS diodes for transient voltage suppression, input fuse for overcurrent protection, and reverse polarity protection. Size TVS for maximum expected transient voltage (typically 36V for 24V systems). Use a fuse rated for maximum operating current with appropriate derating.

Always include TVS protection for industrial power lines; size for worst-case transients in your application.

How do I ensure EMI compliance?

EMI compliance requires attention to PCB layout and filtering: minimize high-current loop areas, use solid ground planes, add input and output filtering, and select appropriate switching frequencies. Follow CISPR 32 layout guidelines and use 4-layer PCB with dedicated ground plane. Pre-compliance testing during development helps identify and fix issues early.

Design for EMI from the start; follow industry layout guidelines; test early with pre-compliance equipment.

What thermal management is needed?

Industrial power supplies often operate in enclosed cabinets with limited airflow. Use adequate PCB copper area (minimum 1 square inch per watt), thermal vias under power ICs, and spread heat-generating components. Verify thermal performance at maximum ambient temperature with no forced airflow. Consider derating output current at high ambient temperatures.

Design for worst-case thermal conditions; verify with thermal testing; consider derating for high ambient temperatures.

Can this solution be customized for different voltage requirements?

Yes, the modular architecture allows easy customization. Different output voltages can be achieved by adjusting feedback resistor values. Additional rails can be added using more XZ2201 or XZ2301 converters. Contact BeiLuo FAE team for assistance with custom configurations and optimization for your specific requirements.

Use modular approach for customization; contact FAE for assistance with custom voltage requirements.
