The JOVYSTAR mega is a real on-line system (double conversion, permanent conversion). The technology of this series is based essentially on our successful series JOVYSTAR delta. Comfortable monitoring and remote control as well as modern SNMP-management are obvious for all units of our whole JOVYSTAR-series, such as the shutdown-software for the common operating systems (optional). These units are optional available with a 12-pulse-input-rectifier, with or without galvanic isolation.
