PSx1200 Power Supply Series

G.M. International new PSx1200 Series power supplies have been designed to provide the greatest levels of availability and safety for high integrity and critical applications.


  • Three independent overvoltage protections: 1 voltage limiting loop at 30 Vdc and 1+1 crowbars at 30 Vdc.
  • Under and over voltage alarm monitoring.
  • High load fuses breaking capacity to ensure that, in case one load attached to the power supply fails, others are not affected.
  • Units are SIL2/SIL3 according to IEC61508:2010 Ed. 2.
  • Designed for installation in Zone 2 / Div. 2 hazardous locations.
  • ATEX, IECEx Certifications.


  • Up to 1200 W for a single unit.
  • Up to 3600 W (fully redundant) for 19" rack system.
  • Better than 89% efficiency with 0.98 Power Factor Correction.
  • Fast output dynamic response.
