ELIABILITY

 

 

These units are extremely reliable and use only the highest quality materials. The number of critical components such 
as electrolytic capacitors has been reduced.

The  Lifetime expectancy shown in the table indicates the operating hours (service life) and is determined by the 
lifetime expectancy of the built-in electrolytic capacitors.  

Lifetime expectancy is specified in operational hours. Lifetime expectancy is calculated according to the capacitor’s 
manufacturer specification. The prediction model allows a calculation of up to 15 years from date of shipment. 

MTBF stands for Mean Time Between Failure, which 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.
