The ECOUPLER 4 is an ultra-compact coupling and decoupling network for burst and surge coupling onto three-phase power lines.

ECOUPLER 4 can be controlled manually from its front panel or automatically from the PC, using the EMVCheck software enclosed with the ECOMPACT 4.

The ECOUPLER 4 is very simple to use, and therefore even first time of infrequent users may operate the unit quickly and easily.

The ECOUPLER 4 conforms to the recent editions of the relevant IEC and EN basic standards for surge and burst testing.
