3.9.1 SITOP modules for the PCU 50.5
Suitable SITOP UPS modules
SITOP UPS modules can continue operation of the PCU 50.5 temporarily if a power failure
occurs and/or shut down the system properly.
In conjunction with the PCU Base Software, all specific applications are taken into account
(e.g. HMI software) with component
Safe shutdown after a power failure of the delivery condition of the PCU 50.5 takes
approximately 20 seconds. For a typical power consumption of approx. 60 W, a capacitor-
buffered UPS with an energy storage device of 7.5 kW is recommended for a PCU 50.5. If
longer buffer times are required, then several expansion modules can be connected in a
cascade connection.
Example of a compatible SITOP UPS module:
SITOP 500S (15 A / 2.5 kWs capacitor)
MLFB: 6EP1933-2EC41
