GMI PSD1220-098 Power Supply

SIL3 Power Supply PSD1220-098, 24Vdc, 20 A, Zone 2 / Div. 2 DIN Rail Mounting

 

The power supply type PSD1220-098 is an anodized aluminium unit. The power supply provides 24 Vdc, 20 A output. The PSD1220-098 unit can be connected in parallel with load-sharing circuitry, which distributes the current load equally to each power supply to increase reliability and reduce internal power loss. The power supply accepts AC power input sources with a nominal voltage range of 110 to 240 Vrms (±10%). Therefore, the lower limit is 100 Vrms, and the upper limit is 264 Vrms. The PSD1220-098 unit has the same AC, DC, Fault and Current Sharing connectors used in the PSD1210 power supply module for easy model-to-model switching.

FUNCTIONS

  • SIL 3 for NE load according to IEC 61508:2010, with one PSD1220-098 module or more PSD1220-098 modules in redundant configuration (see ISM0371 for more information).
  • SIL 2 / SIL 3 for ND Load according to IEC 61508:2010, with two or more PSD1220-098 modules in redundant configuration (see ISM0371 for more information).
  • Systematic capability SIL 3.
  • Power factor correction.
  • Same AC, DC, Fault and Current Sharing connectors used in the PSD1210 power supply module for easy model-to-model switching.
