Siemens SITOP RED1200, SEL1200/1400, BUF1200 add-on modules

Siemens SITOP RED1200, SEL1200/1400, BUF1200 add-on modules

SITOP add-on modules in PSU6200 design provide redundancy, selective load-circuit protection and short-term buffering for SITOP power supplies.

Key features

  • RED1200 redundancy modules for decoupling two SITOP power supplies (12/24/48 V)
  • SEL1200 selectivity modules with switching characteristic, 4 or 8 channels
  • SEL1400 selectivity modules with current-limiting characteristic, 4 or 8 channels
  • SEL1200 48 V/4 x 10 A module with monitoring interface
  • BUF1200 buffer module: 300 ms at 40 A
