EMITER EM-382 DCAC Connection Distribution Board

The EM-382 DCAC connection distribution board is a hermetic, modular solution designed for powering photovoltaic inverters. It provides protection against short circuits and overloads as well as surge protection on the DC and AC sides (SPD Type 2), allowing for external mounting due to its IP65 enclosure rating.

The manufacturer of the device is the Polish company EMITER, specializing in solutions for photovoltaic installations. The EM-382 DCAC model is delivered ready for connection and equipped with components from renowned suppliers (including Dehn surge protectors and Noark equipment), simplifying installation and operation.
