SITOP smart
3-phase, 24 V DC
■
Overview
The three-phase SITOP smart are the universal and powerful
standard power supplies for machinery and plant engineering.
Despite their compact design, they offer an excellent overload
response: Thanks to an extra power of 150 %, loads with high
power consumption can be connected without any problems
and the permanent overload capability of 120% offers power
reserves in case of expansions.
The high degree of efficiency results in low energy consumption
and minimal heat generation inside the control cabinet.
To further increase 24 V availability, the SITOP smart power
supplies can be combined with
buffer
,
DC UPS
,
redundancy
and
selectivity modules
.
