Redundancy Power Supply - 24V, 10 A, 240 W, Single-phase Input
Adjusting the Output Voltage
A voltage adjustment potentiometer can be found behind the flap on the front
of the unit. However, it is not recommended to change the output voltage since
load sharing between power supplies connected in parallel can only be
achieved by a precise setting of the output voltages. The factory settings allow
precise load sharing and only qualified personnel should change the
adjustment potentiometer.
Figure 33 - Adjustment Range of the Output Voltage
The output voltage shall only be changed when absolutely necessary. For
example, battery charging, described next.
Lower end of the specified adjustment range
Output voltage Nom 24.0V
Due to the soft output voltage regulation
characteristic (parallel mode feature) a setting
to 24.0V results to an output voltage of
23.8V±0.2% at 24 A and 25.0V±0.2% at no load.
See
Figure 33 .
Output current
Min 12 A At 45 °C (113 °F)
Min 10 A At 60 °C (140 °F)
Min 7.55 A At 70 °C (158 °F)
Reduce output current linearly b45 °C and +70 °C.
Upper end of the specified adjustment range
Output voltage Nom 27.0V
Due to the soft output voltage regulation
characteristic (parallel mode feature) a setting
to 28.0V results to an output voltage of
27.7V±0.2% at 20.6A and 29.2V±0.2% at no
load. See
Figure 33 .
Output current Min
10.6 A At 45 °C (113 °F)
8.9 A At 60 °C (140 °F)
6.7 A At 70 °C (158 °F)
Reduce output current linearly b45 …70 °C (+113 …158 °F)
The maximum output voltage which can occur at the clockwise end position of the potentiometer due to
tolerances is 30V. It is not a guaranteed value which can be achieved.
Current values between 24 and 27V can be interpolated.
