PULS FIEPOS decentralised power supplies

PULS has released its decentralised FIEPOS power supplies for flexible use directly in the field, with IP54, IP65 or IP67 protection classes. Puls FIEPOS, short for FIEld POwer Supply, represents a new type of power supply that was developed for a decentralised environment. They are designed to be easy to install and flexible enough to meet the diverse requirements of modular factory automation.

Decentralisation improves efficiency and lowers cost by removing the need for oversized supplies and long runs of large cross-section cables.

The field power supplies are available in either Basic Series or eFuse Series. Both series are available with power of 300 or 500 W for single-phase or three-phase systems and as IP54, IP65 or IP67. Both can be DIN rail or surface mounted, with up to 200% power reserve for 5 s and have a wide operating temperature range up to 70°C with derating. The Basic series models have a single DC output. They can be connected in parallel to increase total performance or create a redundant system.

The eFuse supplies have up to four individually current-limited DC outputs, removing the need for external protection. Faults can be monitored and controlled via IO-Link or Output OK signal, plus LED indicators and pushbuttons. In the event an overload, the individual output switches off and needs to be reset manually via pushbutton or remotely via IO-Link.

The use of IO-Link allows for the remote monitoring of output current, quality of the mains voltage, temperature, load variability and status.
