Lifetime expectancy
MTBF SN 29500, IEC 61709
MTBF MIL HDBK 217F
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.
All values except battery.
May. 2008 / Rev. 1.1 DS-UBC10.241-EN
All parameters are specified at an input voltage of 24V, 10A output load, 25°C ambient and after a 5 minutes run-in time
unless otherwise noted. It is assumed that the input power source can deliver a sufficient output current.
