SIL 3 Power Supply System, 48Vdc, 25A not redundant
The Power Supply System type PSS1250-2-48 is an anodized aluminium 7” Rack unit (4U high) suitable to accept 2 plug-in Power Supply Modules type PSM1250. Each PSM1250 module provides 24 Vdc output and PSM1250 modules have their outputs connected in series by internal copper bar, therefore PSS1250-2-48 system provides 48Vdc, 25 A output. The system accepts AC power source from 100 to 264 Vac.
