How can the temperature range impact performance?

The converter maintains efficiency and reliable operation from -40 to +90°C, allowing it to function in different conditions.

What are the recommendations for external fusing?

Specific fuse ratings should be used based on input voltage

for instance, utilise 160 mA (slow blow) for 110V DC models.

How does the I/O isolation benefit the system?

The 3000V DC isolation promotes safety by preventing electrical faults from transferring between input and output, especially in sensitive situations.

What is the significance of the efficiency rating?

With an efficiency of 83%, the converter optimises energy usage and reduces heat generation, thereby improving overall system reliability.
