Introduction
■
Overview
SITOP offers a comprehensive portfolio to protect against power
failures with durations from a few seconds to several hours,
ranging from buffer modules to system-integrated DC UPS units.
Selection is based on the energy storage unit used, the associ-
ated ambient conditions, performance and functionality.
The selection matrix should help you to find the right 24 V buff-
ering for your application:
