SIL3 POWER SUPPLY PSD1220-098, 24VDC, 20 A, ZONE 2 DESCRIPTION The Power Supply type PSD1220-098 is an anodized aluminum unit. The Power Supply provides 24Vdc, 20 A output. PSD1220-098 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. FEATURES • SIL 3 for NE Load according 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 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. • The same AC, DC, Fault and Current Sharing connectors used in the PSD1210 power supply module, for easy model to model replacement. • Installation in Zone 2. • EMC Compatibility to EN61000-6-2, EN61000-6-4. • Highly regulated output of 24 Vdc, 20 A. • Under and over voltage alarm monitoring. • 3 over voltage redundant protections. • Redundant parallel connections with load sharing. • Reduces Power dissipation (in parallel/redundant configuration) by replacing a Schottky diode with Mosfet Active Ideal Diode. • Better than 93% efficiency @230 Vac input, full load and full output voltage range. • High load fuse breaking capability without interrupting operations. • Conformal coated on all boards for durability and protection.
