Pepperl+Fuchs introduces the PS3500 diagnostic module with continuously monitors the health and efficiency of PS3500 power supplies and primary side power conditions. The module provides real time diagnostics with configurable warning and alarm levels, and alerts maintenance and operations personnel to irregularities, faults and impending failures. This promotes proactive maintenance to help eliminate unexpected and expensive downtime. The power supply diagnostic module is modular and hot-swappable, and easily integrates into plant asset management systems through RS485/HART, EDDL or FDT/DTM technologies.

Designed for maximum efficiency and reliability in mission critical and continuous process applications, PS3500 power supplies are up to 91-per-cent efficient and feature a modular design with selectable wiring configurations, enabling them to be configured in N+1 or N+N redundant mode. N+1 and N+N 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 of uninterrupted power, 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.
