PULS FIEPOS
Field Power Supply
Decentralized, Cabinet-Free Power Supplies
The need for flexible, modular systems is shaping machine and system engineering. Decentralization of the system components has proven to be an important factor for success. It speeds up system planning, simplifies maintenance and enables an easy expansion of the system. In addition, control cabinets can be replaced by smaller versions or even completely dismantled.
With FIEPOS, short for FIEld POwer Supply, PULS presents a new type of power supply that was developed precisely for this environment: A decentralized field power supply with protection class IP54, IP65 or IP67 that is readily available, easy to install and flexible enough to meet the diverse requirements of modular factory automation.
In short, PULS' field power supplies are the alternative to a power supply in the centralized control cabinet, decentralized on-site control box or a customer-specific solution.
So what exactly is going on with the power supply in decentralized systems and machine engineering? The products currently available on the market basically allow three different strategies:
1. No decentralization of the power supply
The power supply is not included in the decentralization process and remains in the central cabinets. When it comes to supplying the decentralized peripheral devices in the field, long cable harnesses with a large cross-section have to be taken into account. The power supply has to be oversized due to the loss of performance caused by the long cables.
2. Power supply in a decentralized on-site cabinet
The power supply – along with other standard components such as electronic fuses or switches – is taken out of the central cabinet and placed directly onto the machine in smaller, decentralized IP67 cabinets. Companies often handle the planning and assembly of these cabinets themselves.
3. Customer-specific solution
A customer-specific, decentralized solution is developed especially for the power supply. The size and mechanics are also specifically tailored to the system along with the electrical specifications.
Traditional system design with central IP20 power supply
The centralized supply of peripheral devices in the field requires long cable runs with a large cross-section. Due to the power losses caused by the long cables, the power supply must be over-sized.
Modular system design with IP54, IP65 or IP67 power supplies
FIEPOS field power supplies are perfect for supplying spacious applications with energy in a decentralized, efficient and flexible way. This enables a modular system structure as well as an effective expansion, maintenance and retrofitting of individual components of the system.
Save cost, time and space.
Flexibility
The compact housing with a high degree of ingress protection (IP54, IP65 or IP67) and various connector options enables the FIEPOS power supply to be installed flexibly outside of the control cabinet and directly on the machine.
Ease of Use
The output voltage and the current-limited outputs (eFused series) can be monitored and set directly via the LED interface and the push buttons on the front of the device or remotely via IO-Link.
Cost Savings
FIEPOS field power supplies make it possible to use shorter cables and smaller cable cross-sections. This not only saves on the costs of copper, but also on the installation work for the cabling. In addition, an all-in-one device can be used instead of several components. This means less effort in managing part numbers and less time effort in installation.
Space Savings
Thanks to the integrated, current-limited outputs in the FIEPOS eFused series, no additional protection module is required. This saves space in the system. In addition, centralized control cabinets and decentralized on-site control boxes can be reduced and the space can be used to expand the system. Fewer components also mean more free space in the warehouse.
Field power supply series. The right solution for every application.
Basic series - 1 high-power DC output
The FIEPOS Basic series offers one DC output and is available with a power of 300W or 500W. The IP54, IP65 and IP67 field power supplies are perfect for the decentralized supply of 1-phase or 3-phase systems and machines. The field power supplies can be easily connected in parallel, e.g. to increase total performance or realize a reliable redundant system.
eFused series - Up to 4 current-limited DC outputs
The field power supplies of the FIEPOS eFused series have up to four current-limited outputs. These devices make it easy to implement selective power distribution, protection and monitoring directly in the field. The eFused series is therefore a space-saving, fused power supply system. It is a real alternative to a power supply unit with an external, electronic protection module.

Where can the field power supplies be used?
The potential applications of FIEPOS field power supplies are virtually limitless. That said, modular applications in the field of conveyor systems, storage technology, robotics, control technology, regulation technology, and material handling in particular all benefit from this technology.
Can the device also be mounted on the DIN rail?
Yes, the FIEPOS field power supplies can be mounted in three different ways: By simply attaching it to a DIN rail, by hanging and fixing it in place via the integrated keyholes, or by screw mounting. No matter which option you choose, no additional accessories are required.
Which plug connectors are available?
The FIEPOS field power supplies are available with the following connector types: 7/8”, M12-L/-T/-A, HAN-Q series, and Quickon. Other plug configurations are available on request.
Do the field power supplies have power reserves?
Yes, all devices provide 200% (600W or 1.000W) for 5 s and 120% continuously (at an ambient temperature of up to +45 °C).
What temperature range can the devices be used in?
The FIEPOS field power supplies can be operated in ambient temperatures ranging from -25 °C to +55 °C without any loss of performance. With linear derating, temperatures of up to +70 °C being allowed.
What degree of ingress protection is available?
The robust FIEPOS devices are available with IP54 (dust-protected, splash-proof), IP65 (dust-tight, jet-proof), or IP67 (dust-tight, temporarily immersible) protection, making them well protected against water, dust, and other contaminants.
Which information is available via the IO-Link interface?
Via IO-Link, the FIEPOS power supply provides information about important parameters such as service life, temperature, voltage, current, etc. and alarms of overload, a faulty DC voltage or even if channels are triggered. Remote access is also possible via IO-Link. This enables the device to be switched on and off remotely, the voltage and tripping currents to be set and tripped channels to be reset.
Is it also possible to create NEC class 2 compliant circuits?
Yes, that’s possible with the FIEPOS eFused series. You can set the tripping current to the NEC class 2 standard either directly on the device or via IO‑Link. In the event of an overload, the current is limited for a set period. The current limitation then intervenes to ensure that the maximum permissible power peak of 100VA defined for NEC class 2 is not exceeded at any point.
