Selecting the right power module involves several key steps: 1) Determine input voltage - stable voltage (use fixed input) or varying voltage (use wide input); 2) Calculate output power - sum all load power consumption and add 20-30% margin; 3) Choose isolation level - 1500VDC for general industrial, 2500VDC for power/medical; 4) Select package - SIP for compact space, DIP for harsh environments; 5) Consider special requirements - medical grade, extended temperature, low ripple. Use our selection guides for detailed guidance on DC-DC, AC-DC, and isolated transceiver modules.

Use our selection guides for DC-DC, AC-DC, and isolated transceivers. Contact FAE team for complex applications.

Fixed input DC-DC modules (A series) have specific input voltage (5V, 12V, 24V) with +/-10% tolerance, suitable for stable power supplies. They offer higher efficiency (82-86%) and lower cost. Wide input DC-DC modules (B series) have 4:1 input range (such as 9-36V), suitable for battery power and voltage-fluctuating applications. They provide better flexibility but slightly lower efficiency (80-84%). Choose fixed input for stable voltages, wide input for batteries and fluctuating voltages.

Fixed input for stable voltages (higher efficiency, lower cost). Wide input for batteries and fluctuating voltages (more flexibility).

Isolation is required when: 1) Ground loops exist - multiple ground points causing noise coupling; 2) Safety protection needed - preventing high-voltage faults from reaching low-voltage side; 3) Noise immunity required - blocking common-mode interference; 4) Level shifting - converting between different voltage domains; 5) Medical/safety standards - IEC 60601-1 or similar requiring patient isolation. Isolation is essential in industrial control, medical equipment, communication systems, and power monitoring. For simple, non-critical applications with single ground reference, non-isolated modules may be sufficient.

Use isolation for industrial, medical, communication, and multi-ground systems. Non-isolated may work for simple single-ground applications.
