N+1 Power Supplies from Pepperl+Fuchs

TWINSBURG, OH — Pepperl+Fuchs introduces the PS3500 N+1 High Integrity Power Supply. Designed for maximum efficiency and reliability in mission critical and continuous process applications, PS3500 power supplies are up to 91% efficient and feature a modular design with selectable wiring configurations, enabling them to be configured in N+1 redundant mode. N+1 redundancy guarantees system integrity and performance, even during module failure and replacement.

These 24 VDC, 15 A power modules plug directly into a 3- or 6-position chassis/backplane for maximum capacity of 45 A or 90 A, respectively. The system is designed with external field connectors for easy cabinet layout, LEDs and alarm outputs for quick diagnostic evaluation, and natural convection cooling eliminates the need for external cooling systems. They are certified for Class I Div 2/Zone 2 ATEX Zone 2 mounting.

PS3500 modules are user-adjustable from 22.5 VDC to 30 VDC for precise voltage regulation. Universal supply voltage of 90-250 VAC / 90-300 VDC makes them easy to integrate into an application. They feature configurable load sharing and alarm functions, and provide configuration-free replacement. The PS3500 series is backwards compatible with Pepperl+Fuchs PS2500 series power supplies.

N+1 wiring configurations provide economic reliability and redundancy to a power system. With an N+1 redundant power supply configuration, multiple power supply modules (N) have a backup power supply module (+1) where all modules within the configuration share the load. Should one module in the system fail, the working modules share the load without degrading the integrity of the system.
