but has not been tested for liquids intrusion. In a similar way, a power supply with the code IPX4 has undergone the necessary tests for liquid splashing, but has not been evaluated for the intrusion of foreign objects.
Which IP ratings does PULS offer for its power supplies?

relation to only one of the two codes for foreign objects and liquids. The “X” indicates that the product has not been subjected to the
corresponding tests for this code. Therefore, this is not a variable that can simply be replaced by any of the values from the table of IP ratings.
A power supply with the code IP6X offers full protection against contact and is dust-tight
Table 2
PULS offers a variety of power supplies with the IP ratings described in Table 2. In the light of the increasing trend for decentralisation, the IP rating of industrial power supplies now plays a more important role than it did a few years ago. The DC supply is very often installed directly on the machines, outside the protective cabinet. To ensure the safety of employees and the correct functioning of the power supply, IP54 is required as a minimum across all system components, for example SPS, HMI, sensors.
The decentralised FIEPOS switch-mode power supplies with a high IP rating – IP54, IP65 or IP67 – have been developed for fl exible use directly in the fi eld.
For these applications, PULS has developed the fi eld power supplies in the FIEPOS product family.
