Rockwell Automation 1606-XL240-UPSE Power Supply Reference Manual - Manual (Page 13)

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 noted otherwise.
It is assumed that the input power source can deliver a sufficient output current.

Instructions:
a) Use appropriate copper cables that are designed
for an operating temperature of 60°C.
b) Follow national installation codes and regulations!
c) Ensure that all strands of a stranded wire are properly inserted in
the terminal connection!
d) Up to two stranded wires with the same cross-section are
permitted in one connection point.
17. Reliability
Lifetime expectancy
min. 137 400h At 10A output current, 40°C
min. > 15 years At 5A output current, 40°C
min. > 15 years At 10A output current, 25°C
MTBF SN 29500, IEC 61709 886 000h At 10A output current, 40°C
1 482 000h At 10A output current, 25°C
MTBF MIL HDBK 217F 397 900 At 10A output current , 40°C, ground benign GB40
545 000 At 10A output current , 25°C, ground benign GB25
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 manufacturing specififications. The prediction model
allows a calculation of up to 15 years from date of shipment.
MTBF stands for Mean Time Between Failures, which is calculated according to statistical device failures and indicates
reliability of a device. It is the statistical representation of the likelihood of failure of a specific unit and does not
necessarily represent the life of a product.
