Redundant Power Supplies

Power supply redundancy is important for increasing system reliability. Industrial facilities depend on bulk power supplies as they power the control system architecture and the process measurement instrumentation. Business critical applications can’t afford to be offline due to a power supply failure which could lead to a substantial amount of lost revenue for every minute the process is down.

This need for system integrity and dependable performance in demanding conditions necessitates power redundancy. N+1 and 1+1 are two reliable redundancy methods that ensure system functionality even during a power failure.

PS1000 Power Supplies


N+1 and 1+1 Topology?

The PS1000 Power Supplies can be used redundantly in both an N+1 and a 1+1 topology. With an N+1 redundant configuration, multiple components (N) have at least one independent backup component (+1) ensuring continued functionality during power loss. All the modules in a configuration share the load and if a system module fails, the functioning modules continue to share the load without compromising system integrity.

The 1+1 configuration provides redundancy with 2 power modules of the same power coupled by a MOSFET to supply the same load. Using MOSFETs instead of diodes in the redundancy function reduces heat generation and the voltage drop between input and output.

Utilising Redundancy with the PS1000 Power Supplies

These capable power supplies can be used in redundant topologies by using an external redundancy module (PS1000 XXX. RM) that has a decoupling MOSFET on the input, allowing for the connection of 2 power supplies for 1+1 redundancy, or by using a (PS1000 XXX. R) power supply with a decoupling MOSFET for limited space applications.

For power applications requiring less than 40 Amps, 1+1 redundancy is an economical solution when a redundant power system is required, N+1 is for critical applications. The versions featuring IO-Link offer a future-proof interface that allows comprehensive diagnostics and configuration processes to be carried out during operation.

Intrinsically Safe Power

The King of Level Sensors – The KingCrown CleverLevel PL20 Series from Baumer

Down with Vibrating Fork Sensors, long live the King! The KingCrown CleverLevel PL20 Series Level Sensors are setting the stage as the most dependable and versatile level detection solution for a wide variety of troublesome media and processes.

With an adaptive-trigger function, these capable level sensors are a step ahead of vibrating fork sensors, automatically adjusting to all media without parameterisation. Applications vary from dry running protection for pumps through reliable overfill protection or leak detection to the selective detection and masking of foam or separating layers.

360 Degree Process Visualisation, Even in Daylight!

Robust process visualisation is built-in using 360° LEDs which provide real-time information on the process status, with 5 defined colours which can indicate whether the process is working as intended, the sensor is switching, or if there is an issue. Additionally, the colours can be used to indicate which medium is being measured and analogue values ranging from 4…20mA can be read out.

It doesn’t matter whether it’s bulk goods, powders, liquids or foam, or if the medium is sticky or has high or low viscosity, the KingCrown Level Sensor is the new King in town!

During industrial cleaning processes, such as CIP cleaning, sensors can switch incorrectly as they cannot differentiate between the process and cleaning media. The PL20 Level Sensors master this challenge by ignoring cleaning media. Also, media adherence, which can be caused by pasty materials, doesn’t affect these sensors, which adjust their switching level without the need for parameterisation.


Hot, Humid, No Problem!

In very humid areas, or those with temperature changes or water spray, a rugged impermeable design is needed to prevent sensor malfunctions. With exceptional resistance to impacts and fracturing during installation and production the KingCrown PL20 Series is perfect for demanding working conditions. Designed according to Baumers proTect+ Impermeability Concept, the PL20 Level Sensors are ideal for these challenging conditions. (Learn more about the Baumer proTect+ here).

Beverage and Rugged Industrial Application Versions

A built-in IO-Link interface provides easy access to valuable data, additionally it allows easy, location-independent parameterisation of the level sensor.

Available in two versions, with multiple mounting options, the PL20H for Food and Beverage process use and the PL20S variants for demanding high-pressure industrial applications.

PL20 Series Level Sensor Features and Benefits

  • 5 Multicolour LEDS, 360° real time status display even in daylight
  • Versions for Hygienic and Industrial applications, can be used in open tanks
  • Long term impermeability over entire service life according to Baumer proTect+
  • Measuring principle – Frequency sweep

A Change is Brewing – the VLT AutomationDrive FC 302 – Making Beer Smarter

Within industry today terms such as ‘Smart Maintenance’, ‘Smart Factory’ and the ’Factory of Tomorrow’ are becoming more and more commonplace.

These terms are the ideal end goal for many businesses, ultimately leading to a highly efficient and well-run operation.  Making the transition to a Smart Factory isn’t without its challenges and can feel more like a leap into the unknown, rather than a small step in the right direction.

Brewing giant HEINEKEN decided that to secure a more robust and sustainable future in its Netherlands based Den Bosch facility, required stepping into unknown territory by using the innovation offered by Danfoss VLT drives with integrated condition-based monitoring (CBM) capabilities to reach their goals.

By 2025 the European beer market is expected to have grown by a further 15.2%, HEINEKEN knows that to meet this expected growth their production lines must always be on task with all assets delivering a reliable and consistent performance 24/7.

VLT AutomationDrive FC302

Producing beer on a large scale can be demanding, and with all applications containing difficult to access motors Heineken faced costly and lengthy disruptions whenever a machine fault occurred.

Danfoss was tasked with helping the brewery to:

  • Increase uptime
  • Lower overheads
  • Improve management of spare parts and stock
  • Access new levels of machine data
  • Boost application and system performance

Technology with the Edge

Danfoss Drives proposed HEINEKEN install VLT AutomationDrive FC 302 drives with embedded intelligence, connectivity, and sensor capabilities. Condition-based monitoring signals were integrated into the brewery’s maintenance system using edge computing.

The brewery also utilised some vibration sensors and Danfoss assisted further with project scoping, commissioning, training, as well as holding workshops.

As the VLT drives also support existing industrial ethernet communication interfaces and software such as VLT Motion Control Tool MCT 10, meant that HEINEKEN didn’t have to invest in new parallel systems as part of the upgrade.

Jan Brouwers, Detail Engineer at HEINEKEN’s Den Bosch said – ‘Condition Based Monitoring is a great addition to an already very good drive. Now, HEINEKEN is standardised on the VLT AutomationDrive FC 302.’

VLT AutomationDrive FC302

An Optimised Conclusion

The VLT Motion Control Tool MCT 10 plug-in was a game changer, enabling seamless commissioning with consistent parameter settings, with the power to gather more critical application data in real time than ever before. HEINEKEN, thanks to the efforts of Danfoss Drives, was able to optimise its Den Bosch production line while solving all its pain points while building a total value proposition.

As a result, HEINEKEN retrofitted the rest of its drives in its other facilities with condition-based monitoring functionality. The Den Bosch upgrade proved that condition-based monitoring is no longer a premium product meant for a few critical assets, but an affordable solution for all.
