PSD1220-098

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

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. The Power Supply accepts AC power input sources with nominal voltage range 110 to 240 Vrms (± 10%). Therefore lower limit is 100 Vrms and upper limit is 264 Vrms. PSD1220-098 unit has got the same AC, DC, Fault and Current Sharing connectors used in the PSD1210 power supply module, for easy model to model replacement.

• 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/Div. 2 hazardous locations.
• 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.
• Highly regulated output of 24 Vdc, 20 A.
• Under and over voltage alarm monitoring.
• 3 over voltage redundant protections.
