What is the difference between storage temperature/humidity and preservation temperature/humidity?

Are there any precautions when connecting series and parallel at the same time?

What power supplies can be used for battery charging?

Please explain the effects of motor drive applications on switching power supplies.

Please explain how to interpret the ambient temperature of power supplies.

What is MTBF?

How can I check the useful life of a product?

There are products that indicate time to failures with MTBF and those that indicate time to failures with MTTF, but what is the difference between the two?

Please explain what the FIT rate is as the failure rate.

What is the specific area where the temperature must be measured to find the ambient temperature?

What storage method do you recommend for the power supply?

If a fan malfunctions, can I replace it myself?

What should be done if the input side fuse of the power supply has become fused?

What happens during use if the sensing wires are accidentally left open?

Please explain the checkpoints for when there is an operational failure.

Please explain the checkpoints for when there are no outputs.

Please explain the checkpoints for when the output voltages are low.

Please explain the checkpoints for when the outputs are abruptly stopped.

Please explain the checkpoints for when the outputs are unstable.

Please explain the checkpoints for when the ripple and noise are high.

The cover of power supply was unnecessary. Is it OK to use the product with the cover removed? (On the other hand, the cover was necessary. Do you sell only the cover separately?)

The output LED is flashing. Is this normal?

There are no products with the needed output voltage in the catalog. Is there any way to get around this?

How do you select diodes for series operation and parallel operation (backup)?

Please provide the recommended breaker (circuit protector) capacity.

Can an appropriate housing for the connectors be purchased?

I want to purchase a terminal cover separately.

Can you provide the results of the FTA and FMEA?
