Temperature affects both efficiency and power rating, with the converter operating at full capacity up to +55°C without derating, and up to +80°C with derating.

This feature protects the device by preventing operation below defined voltage thresholds, ensuring reliability and avoiding potential damage.

Yes, up to three units can be connected in parallel for enhanced current sharing, effectively increasing overall output capacity while maintaining performance levels.

It includes constant current mode protection, which automatically limits output current when thresholds are exceeded to prevent damage.

Output voltage can be tuned using an onboard trim potentiometer, allowing for specific voltage needs within a range of 19.2V to 28.8V DC.
