PULS: FIEPOS – IP54, IP65 & IP67 Field Power Supplies
March 18, 2026
FIEPOS: Field Power Supply Series – The Right Solution for Any Application
The decentralized FIEPOS power supplies with high protection classes IP54, IP65 and IP67 were developed for flexible use directly in the field.
With FIEPOS, short for FIEld POwer Supply, PULS presents a new type of power supply that was developed precisely for decentralized applications: A field power supply with protection class IP54, IP65 and IP67, that is easy to install and flexible enough to meet the diverse requirements of modular factory automation. The efficient 300 W and 500 W field power supplies fit in a very robust and compact housing.
Various versions are available from stock – including current-limited outputs for selective current distribution, a variety of plug connectors, IO-Link as a communication interface, and decoupling MOSFETs for developing redundant systems. 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.
Overview
Basic Series
1 high-power DC output
The FIEPOS Basic series offers one DC output and is available with a power of 360 W or 600 W. The IP54, IP65 and IP67 field power supplies are perfect for the decentralized supply of 1-phase or 3-phase systems and machines.

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.

Upgrade: Decentralization Made Easy
Until Now
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.
New
Modular System Design with IP54, IP65 & 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.
Benefits: Save Costs, Time & Space
- Flexibility: The compact housing with a high degree of ingress protection (IP54, IP65 and 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 Supplies: The Alternative to a Cabinet
The FIEPOS eFused power supply is also available with a current-limited high-power channel (20 A) and an additional fused low-power channel (2–12 A). The compact field power supply can be attached directly to the machine and replaces decentralized on-site cabinets such as those comprising a 24 V 20 A power supply and an electronic fuse for creating an electric circuit compliant with NEC class 2 standards.
With the eFused version, it is no problem to supply decentralized loads with a high energy consumption and set up a NEC Class 2 circuit at the same time. This means that the compact IP54, IP65 and IP67 power supplies can replace on-machine control boxes that consist of a 24 V 20 A power supply and an electronic fuse.
The graphic shows how you can save material costs, working hours and space by using FIEPOS field power supplies.
