2.1 Device description
2.1.1 Redundancy modules
2.1.1.1 SITOP RED1200
Redundancy modules SITOP RED1200 are the optimal addition to all 12 - 48 V power supplies
to provide additional protection against failure of the 12 - 48 V supply. The redundancy
module continuously monitors the feeding power supplies, and when one device fails, the
other one automatically takes over the complete 12 - 48 V supply.
12 - 48 V input – supply voltage from power supplies 1 and 2
12 - 48 V output – supply voltage to the load and 0 V connection to the internal supply
