❓ Frequently Asked Questions

What is the difference between MTBF and Life Cycle?

MTBF (Mean Time Between Failures) is a statistical prediction of reliability based on component counts. Life Cycle is an estimate of the power supply's actual lifespan based on the temperature rise of electrolytic capacitors.

Why is the input voltage range on the spec sheet different from the label?

Spec sheets show the absolute operating range (e.g., 88~264 VAC) for flexibility. Labels show the standard range (100V~240VAC) to meet strict safety verification standards and ensure correct user input.

How do I choose the right power supply for battery charging?

We recommend choosing a model where the Over Load Protection (OLP) mode is constant current limiting. This ensures a steady current even when protection circuits are triggered during high demand.

Is this charger compatible with different global plug types?

Yes, our desktop chargers support various socket types including USA, Canada, EU, and UK standards to ensure global compatibility.

What safety protections are built into the 48V 3.5A charger?

The charger includes integrated protection against short circuits, over-current, and over-voltage to ensure safe operation for both the device and the battery.

Does environment temperature affect the charger's performance?

Yes, in high-temperature environments, we suggest derating the output power. The charger is rated for optimal performance between -29ºC and +45.5ºC.
