Direct Supply with Power Supply

A complete power solution for a K-System installation is possible by using the following 

power supplies:

KFA6-STR-1.24.4 from 115/230 V AC to 24 V DC/4 A or

KFA6-STR-1.24.500 from 115/230 V AC to 24 V DC/500 mA

The power supplies snap on the Power Rail to easily and efficiently distribute power 

to the isolated barriers.
