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%).
- 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).
- Systematic capability SIL 3.
- Power factor correction.
- Installation in Zone 2/Div. 2 hazardous locations.
- Tropicalization for electronic components.
- 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.
- 89% efficiency @230 Vac input and 24 Vdc output and full load.
- Fan speed control depending on ambient temperature and output power.
- High load fuse breaking capability without interrupting operations.
- Highly regulated output of 24 Vdc, 50 A, for PSW1250 module.
- Under and over voltage alarm monitoring.
