Protection against short-time voltage dips
For a drop in the line-side supply voltage, the 24 V power supply still maintains the output
voltage for a short time in the millisecond range (see Chapter Technical data (Page 53)).
For line supplies that manifest frequent brief voltage dips, in order to increase the power
supply reliability, it may make sense to increase the line buffering time in the device using an
additional SITOP PSE201U buffer module.
The SITOP PSE201U buffer module, based on electrolytic capacitors, is connected in
parallel to the power supply output (Figure 9-6 Buffering brief power failures using the
SITOP PSE201U buffer module (Page 99)). The buffer time is 200 ms at 40 A up to 1.6 s for
a load current of 5 A. This time can be increased a multiple number of times by connecting
buffer modules in parallel; the maximum buffer time is 10 s.
