➧
To set the UPS output frequency (Hz)
Nominal Value : to set a numerical value for the output
frequency (50 or 60)
Auto Selection :
If enabled, the UPS reads the frequency of the input
voltage and then synchronises the output to the same
value.
If disabled, the UPS uses the set
Nominal Value .
NB: Redundancy Settings
This function is used to manage the redundancy of the power modules. For example: a load requires N power
modules; X power modules must be added to achieve N+X redundancy.
If the load applied exceeds the power supplied by N modules during operation, the UPS will signal the lack of
redundancy
A numerical example is given below:
