Eliminate Downtime in Mission Critical and Continuous Process Applications with PS3500 Power Supply Diagnostic Module from Pepperl+Fuchs



Diagnostics module continuously monitors power supply health and primary side power conditions to minimize and even eliminate unexpected and expensive downtime



TWINSBURG, OH – Pepperl+Fuchs introduces the PS3500 Diagnostic Module. The PS3500-DM 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.



“Those who have experienced a power failure, particularly in mission-critical and continuous process applications, know that a single power supply failure can have a catastrophic effect,” says Robert Schosker, Product Manager. “The PS3500 diagnostic module provides the greatest level of protection possible and is an absolute must-have in all mission-critical loops. It monitors mains, output, power supplies and diagnostics to maintain system integrity. The module alerts personnel to faults or impending failures from the power supply and indicates the necessary corrective action, enabling them to shift from costly reactive-based maintenance to condition-based maintenance that keeps processes up and running efficiently.”



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 or N+N redundant mode. N+1 and N+N redundancy guarantees system integrity and performance, even during module failure and replacement.



“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,” explains Schosker. “N+N configurations provide redundancy using two power supply modules that share the load equally.”



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.
