The voltage relay XU1DC of the easy PROFESSIONAL LINE is a digital relay for voltage supervision of DC systems.

Type XU1DC1, with a nominal voltage range of 100 to 500 V, is mainly used for supervision of DC intermediate circuits, UPS batteries and station batteries.

Type XU1DC2, with a nominal voltage range of 24 to 60 V, can be used for the supervision of starter batteries, for example.
