DESCRIPTION
The Power Supply type PSW1250 is stainless steel AISI 304 unit. The Supply provides 24Vdc, 50 A output. PSW1250 unit can be paralleled, with load sharing circuits, which distribute current load equally to each power supply to increase reliability and reduce internal power dissipation. The Supply accepts AC power sources with nominal voltage range 110 to 240 Vac (±10%).
FEATURES
SIL 3 for NE Load according IEC 61508:2010, with single PSW1250 module or more PSW1250 modules in redundant configuration (see ISM0220 for more information).
SIL 1 for ND Load according to IEC 61508:2010, with single PSW1250 module (see ISM0220 for more information).
SIL 2 for ND Load according IEC 61508:2010, with more PSW1250 modules in redundant configuration (see ISM0220 for more information).
