G Safe connection to the

G Safe connection to the grid VMD460 – Interface Protection System (decoupling protection) compliant with the standards for photovoltaic systems, CHPs, wind and hydroelectric power The VMD460 provides external interface protection system that isolates the connection between the public grid and the power generation system by operating interface switches in case of limit infringements. If voltage and frequency measurements on the power generation system are outside the thresholds required in the standards, the power generation system is isolated from the public grid. The VMD460 is multifunctional and can be used in many applications based on national or plant-specific requirements. The related parameters are saved in pre-set basic programs. The VMD460 combines safe function with a high degree of flexibility and straightforward configuration.
