Description:

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 from 100 to 264 Vac.

Overvoltage protection:
3 independent overvoltage protections: 1 voltage limiting loop at 30 Vdc and 1+1 crowbars at 30 Vdc.
EMC:
Fully compliant with CE marking applicable requirements.
High load fuses breaking capability:
In case of short circuit on the load, the Power supply system delivers a very high peak current (about 800 Amp) for a duration of 0.5 ms. This characteristic ensures the instant breakage of the protective fuse or circuit breaker. Because of the very short peak current duration, other equipment connected to the load are not affected by the failure event and continue to operate without interruption.

Features:

• Power factor correction.
• Installation in Zone 2 / Div. 2 hazardous locations.
• EMC Compatibility to EN61000-6-2, EN61000-6-4.
• Highly regulated output of 24 Vdc, 50 A, for PSW1250 module.
• 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.
• 89% efficiency @230 Vac input and 24 Vdc output and full load.
• Speed fan control depending on ambient temperature and output power.
• High load fuse breaking capability without interrupting operations.
• Tropicalization for electronic components.
