Mean Time Between Failure
Mean Time Between Failure (MTBF) is calculated according to statistical
device failures, and indicates reliability of a device. It is the statistical
representation of the likelihood of a unit to fail and does not necessarily
represent the life of a product.
The MTBF value is a statistical representation of the likelihood of a device to
fail. An MTBF value of, for example, 1,000,000 h means that statistically one
unit fails every 100 hours if 10,000 units are installed in the field. However, it
cannot be determined if the failed unit has been running for 50,000 h or only
for 100 h.
For these types of units, the Mean Time To Failure (MTTF) value is the same as
the MTBF value.
Electromagnetic
Compatibility
The electromagnetic compatibility (EMC) behavior of the device is designed
for applications in industrial, residential, commercial, and light industrial
environments.
The device complies with EN 61000-6-1, EN 61000-6-2, EN 61000-6-3, EN
61000-6-4, EN 61000-3-2, and EN 61000-3-3.
The device complies with FCC Part 15 rules. Operation is subjected to following
two conditions: (1) this device may not cause harmful interference, and (2) this
device must accept any interference received, including interference that may
cause undesired operation.
Do not use this device in an application where both of the following are true:
• The device is used on AC 100V mains with more than 3.6 A load.
• The application is sensitive to short output voltage dips during mains
interruptions, even with a length shorter than 20 ms.
