PSD1220

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

The Power Supply type PSD1220 is an anodized aluminum unit. The Power Supply provides 24Vdc, 20 A output. PSD1220 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.

• SIL 3 for NE Load according IEC 61508:2010, with single PSD1220 module or more
• PSD1220 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
• modules in redundant configuration (see ISM0371 for more information).
• Systematic capability SIL 3.
• Power factor correction.
• Installation in Zone 2/Div. 2 hazardous locations.
• Reduces Power dissipation (in parallel/redundant configuration) by replacing a Schottky
