Innovation in Power Supply Design needs to stay ahead of the market


Marco van der Linden, UK Country Manager for PULS Power T


he power supply is the heart of any system. This is a role it has held for decades, working tirelessly away in the background from inside the cabinet. However, developments in recent years, including the advance of IIoT and Industry 4.0, have seen the power supply increasingly distance itself from this modest role. The variety of applications – not to mention the requirements that go with them – are driving this evolution. The result is that, in addition to the essential function of a power converter, there is a growing demand for complete power supply systems featuring integrated communication, redundancy and protection functions. And then of course there is the emergence of decentralisation, which also has a crucial role to play with regard to next generation power supply design and current distribution.


If we want to be able to meet this demand with standard products and avoid costly time-consuming custom designs, a flexible product platform is needed to form the basis for implementing the various solutions required. This platform also cannot compromise the fundamental qualities of a power supply, which include outstanding efficiency, a compact design, exceptional reliability and a long service life. It is with all of this in mind PULS have gone back to the drawing board to develop a new genre of decentralised power supply - FIEPOS – our decentralised power supply system. These innovative highly efficient 300W and 500W power supplies are housed in a very compact and robust enclosure that offers a high level of IP protection (IP54–IP67). They are available in various versions ex stock, including current-limited outputs for selective current distribution, a variety of different connectors, IO-Link as a communication interface, and efficient decoupling MOSFETs for developing redundant systems. FIEPOS is an all-in-one device that can be used instead of several conventional components, reducing parts lists and component sourcing as well as simplifying and speeding up installation and commissioning.


Decentralisation improves the system planning process, facilitates straightforward system expansion, simplifies maintenance tasks and reduces potential system downtime. More and more system components are being relocated directly into the field and are required to be provided with a degree of environmental protection from IP54 to IP67. FEIPOS also meets designer’s ongoing requirements to make central cabinets


smaller than ever or even dispensed with entirely. Many systems integrators have already acted after recognising the benefits of a decentralised power supply, starting right at the system planning process to take advantage of this increased flexibility. There are many applications, such as conveyor belts, production lines, or rail infrastructure that can be supplied with energy much more efficiently and flexibly on a decentralised basis. The power supply no longer must be oversized to contend with losses in long cable runs as cable lengths and cross-sections can be reduced, improving energy efficiency and making savings on the cost of copper. In addition, the individual system parts can be put together on a modular basis allowing them to be extended, maintained and converted more quickly and effectively than ever. By making the cabinets smaller, or even doing away with them entirely, the newly gained space can also be used to expand added- value system components.


The all-in-one solution:


The new FIEPOS Field power supply family is based on a modular platform developed specifically for use outside of a cabinet providing decentralised field power supplies with protection classes of IP54, IP65 or IP67. All models are based on either 1-phase or 3-phase input power with either a 300W or 500W output rating. All devices in the FIEPOS family provide 120% power continuously (up to +45°C) and 200% for 5s making them suitable for loads with a demanding start-up cycle.


The FIEPOS product family has two versions: The FIEPOS Basic series has a single DC output and is available an optional integrated decoupling MOSFET allowing units to be easily connected in parallel to increase total output power or to configure a redundant system for increased reliability.


The eFused series:


With a housing size of only 182 x 183 x 57mm (WxHxD), they can be installed in applications where space is at a premium. The units can be mounted via DIN-Rail or in place using a variety of mounting holes.


FIEPOS power supplies are manufactured using a combination of modular boards futureproofing them by


Is available with up to four current-limited DC outputs simplifying the delivery of selective current distribution, protection and monitoring directly in the field, with no need for any further accessories, or costly, bulky enclosures. The eFused series provides a compact, space saving electronically fused power supply system and it is a real alternative to a power supply unit with an external, electronic protection module. The PULS FIEPOS series opens up a whole new world of possibilities for system developers and integrators when considering modern system planning and implementation. Whether a designer is looking for a centralised or decentralised solution, PULS can ensure that the power supply remains the reliable heart of any system for the foreseeable future.

allowing new functions to be added by simply integrating alternative boards as required. The all-in-one device can be used instead of several components reducing the complexity of managing multiple part numbers and taking less time to install.
