Reference Manual

All parameters are specified at 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.

Fig. 15-1 Spring-clamp terminals, connecting a wire
1. Insert the wire 2. Close the lever
To disconnect wire:
reverse the procedure
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 fully
inserted in the terminal connection.
d)
Up to two stranded wires with the same cross-
section are permitted in one connection point.
16. 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 specied in operational hours.
Lifetime expectancy is calculated according to the capacitor’s manufacturer specication. 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 given unit and does not
necessarily represent the life of a product.
