DC UPS with capacitors

Technical specifications
The UPS500S can be extended to 20 kW using UPS501S expan-
sion modules to extend the buffering time.
The table shows the maximum buffering time for the possible
configurations and the two UPS500P units for different load
currents.
The charging current can be set to 1 A or 2 A with the UPS500S.
Selection table SITOP UPS500 (optional with SITOP UPS501S expansion module) and mains buffering times
Important information for selecting the energy storage units:
When the mains buffering times were determined, the discharge
period of new or non-aged, completely charged capacitors was
used as a basis.
At a continuous ambient temperature of +50 °C, a loss of capac-
ity of approx. 20% must be considered after a service life of
8 years.
