The Emparro three-phase power supply line now includes a 40-A model that also has a preventive diagnostic function. This function notifies users of the need to replace the power supply. The notification is given just in time. When the signal is given, no immediate action is required. Replacement can take place during the machine’s next regularly scheduled maintenance. This puts the focus on action rather than reaction. Integrated reserve power allows the unit to be used in areas with ambient temperatures of up to 45 °C with 20% overload, so 40 A becomes 48 A.
