COMPANY PRESENTATION

Now that Pepperl+Fuchs has built up a world-leading position with end users andcontrol system manufacturers for conventional interface devices for intrinsicallysafe explosion protection, we are using these established sales paths for newproduct families.

Confirming our strong tradition of power supply manufacturer, this brochuredescribes our high integrity 24 V power supply for powering intrinsic safetycabinets, field instrumentation and conditioning systems. The power supplysystem PS1550 is particularly suitable for critical applications such as EmergencyShutdown and Fire & Gas protection systems.

Finally, the recently acquired display and operating terminal (HMI) from the EXTECbrand will enable us to enter the field of diagnosis and configuration platforms forfield bus technology, whilst our level control products cover the field devicerequirements to round off our overall strategy.

Our target industries are involved in chemicals and pharmaceuticals, petrochemicals, and other areas involving waste water treatment and power technology. In all industrial areas Pepperl+Fuchs is both a supplier and partner for endusers, control system manufacturers, system integrators and engineering contractors.

Your pathway to precision and performanceThe Process Automation division of the Pepperl+Fuchs Group, of whichPepperl+Fuchs Elcon is a 100% daughter company, is today the undisputedmarket leader in all three World markets – America, Europe and Asia – when itcomes to components for intrinsically safe explosion protection.

PS1550 System Overview

Fault Tolerant

Both the ac supply and 24 Vdc output can beconfigured with redundant n+1 modules formission critical applications.

Full Alarm Monitoring

All critical functions are automaticallymonitored and indicated by LED’s and alarmrelay outputs.

Hot Swappable ModulesAll modules are hot swappable on-line,ensuring your 24 Vdc is available at all times.

High Power Output!

Up to 36 Amps @ 24 Vdc is

available and all modules load share and automatically

adjust to the load.

Front Panel Test Jacks

Output modules include LED indicators and testjacks for current and voltage output calibration.

Choice of Mounting

19” Rack with front or rear flanges formounting.

Tagging

Provided on the front of every module.

Integral Cooling FansThree cooling fans with LED indicators are monitored by the internal alarm system.

Mission Critical Power Supply

PS 1550 System

A 4U High 19” rack mounting system, with integral cooling fans, a choice of 3 alternate plug-in output termination modules, 2 Supply (1550/LM) Line Modules and up to 6 (1550/PM) Power Modules.

Each Power Module provides 6 Amps at 24 Vdc.

Using 2 Line Modules and a n+1 Power Module strategy, the PS 1550 provides a unique mission critical capability.

High Output With Full Redundancy

� Maximum output of 36 Amps at 24 Vdc nominal per rack using six 1550/PM Power Modules.

� Fully redundant configuration provides 30 Amps at 24 Vdc, with n+1 (1550/PM) Power Module and two (1550/LM)Line Module failure strategy.

� With a fully redundant strategy the system is tolerant to theloss of 1 Supply Line and 1 Line Module or one or more PowerModules.

� Load sharing across all Power Modules ensures that the load is supplied evenly on failure of a Power Module withautomatic adjustment to the present load.

� Mixed AC/DC input capability permits battery back-up without the need for a UPS.

� Unlike current fold back designs the PS 1550 supplies fulloutput (60 Amps total) in a short circuit, instantly clearing afaulty fuse to avoid voltage spikes affecting other units on thesame supply bus.

Self Monitoring � Under permanent ( > 10 sec.) overload, the output is

automatically disconnected to prevent a cable fire.

A short pulse transmitted every 10 seconds will restart theoutput automatically when the fault is removed, to avoid on-site manual restart procedures.

Integral Alarm Monitoring

� All critical functions are automatically monitored andindicated by LEDs and relay outputs.

� Output integrity is maintained even in the event of loss of:

- Supply line.

- Line Module.

- Power Module.

- Cooling fan module.

� Alarm monitoring provides a contact ouput for:

- Low voltage on supply lines.

- Low voltage on output bus.

- Power Module overload, with LED indication.

- Power Module low output.

- Power Module internal fault.

- Power Module temperature limit protection, to prevent destructive failures.

- Failure of one of the three integral fans, LEDs indicate which fan has failed.

� Two relay outputs are provided for users to set and/or alarmfunctions.

Hot Swappable Plug-in Modules

� Modular load sharing design including “Hot Swappable”modules with self detection and signalling of faults,minimizes servicing and maximises MTTR (Mean Time ToRepair).

� Easy upgraded while on-line, by plugging in extra PowerModules.
