The Power Supply type PSM1250 is an anodized aluminum unit for PSS1250. The Supply provides 24Vdc, 50A output.
Modules can be paralleled on PSS1250 with load sharing circuits which distribute current load equally to each power supply module to increase reliability and reduce internal power dissipation.
The Supply accepts AC power sources from 110 to 240 Vac (+/- 10%).
- SIL 3 for NE Load according IEC 61508:2010, with single PSM1250 module or more
- PSM1250 modules in redundant configuration (see ISM0219 for more information).
- SIL 1 for ND Load according to IEC 61508:2010, with single PSM1250 module
- (see ISM0219 for more information).
- SIL 2 for ND Load according IEC 61508:2010, with more PSM1250 modules in
- redundant configuration (see ISM0219 for more information).
- Systematic capability SIL 3.
- 2 universal AC Input Lines, nominal 110 to 240 Vac (±10%) (48 to 62 Hz).
- Power factor correction.
- High load fuse breaking capability without interrupting operations.
- Module for 19” or 9” or 7” Rack unit, 4 U high,anodized aluminium, durable metal enclosure.
- Tropicalization for electronic components.
- Module parameters are visible by Modbus RTU RS-485 diagnostic output (with PSO1250 diagnostics only for 19” or 9” rack units).
- 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 with full load.
- Fan speed control depending on ambient temperature and output power.
- Installation in Zone 2 / Div. 2 hazardous locations with hot swappable modules.
- Highly regulated output of 24 Vdc, 50 A, for PSM1250 module.
