Using a SITOP power supply as an alternative to a load power supply
Alternatively, an external 24 V power supply from the SITOP range

) (SITOP smart
or SITOP modular) can be used:
●
For higher output currents and 1-phase or 3-phase infeed
●
With redundant installation of the 24 V power supply as protection against failure of a
power pack
●
With buffering of the 24 V power supply (e. g. with DC UPS) as protection against power
failure
●
With selective monitoring of 24 V loads against overload or short-circuit
