GMI PSM1250 Power Supply System Power Supplies

DESCRIPTION

The Power Supply type PSM1250 is an anodized aluminum unit for PSS1250. The Supply provides 24Vdc, 50A output. Modules can be paralleled on PSS1250 with load sharing circuits which distribute current load equally to each power supply module to increase reliability and reduce internal power dissipation. The Supply accepts AC power sources from 110 to 240 Vac (+/- 10%).

FEATURES

SIL 3 for NE Load according IEC 61508:2010, with single PSM1250 module or more PSM1250 modules in redundant configuration (see ISM0219 for more information).

SIL 1 for ND Load according to IEC 61508:2010, with single PSM1250 module (see ISM0219 for more information).

SIL 2 for ND Load according IEC 61508:2010, with more PSM1250 modules in redundant configuration (see ISM0219 for more information).

Systematic capability SIL 3.

2 universal AC Input Lines, nominal 110 to 240 Vac (±10%) (48 to 62 Hz).

Power factor correction.
