Characteristics

Given the current requirements of new smart grid developments, the ZGR MIT range represents a major evolution in customisation and innovation over the conventional ZGR MIT range.

The new single-phase and three-phase ZGR MIT systems allow the user to have high quality DC power at the same time as the highest performance required by Smart Grids.

The wide knowledge of Zigor in this type of solution has allowed to adapt to the fast trend of the market, providing the customer with a differential value in monitoring and configuration of the characteristics of the power solution at both hardware and software level.
