The PowerLogic DVR series offer to industry a solution to regulate voltage and restore Sags. This equipment is part of the Dynamic Voltage Restorer solution, and do not work stand alone. The secondary unit brings additional capacity to the system power. Protection of sensitive loads in power distribution and transmission systems against voltage distortions. Two of those secondary equipements combined with the main apparatus contribute to the -40 % sags correction at 400 VAC, for a system power of 900 kVA. Enclosure dimensions are 2152 mm in height, 1214 mm in width and 750 mm in depth, and a total weight of 1250 kg. The device passed the following tests: SEMI F47 (US) / IEC 61000-4-34 for sags performances, and received CE, Ctick and EAC certifications. The enclosures is floor standing, equiped with hinged doors locked by a special opening tool. Include a forced ventillation to cool the inverter and the transformer. The design of the equipement allows connection to Source and Loads from the top or bottom, but to DVR input and output only from the bottom. This asset is compatible with EcoStruxure Power Advisor and EcoStruxure Asset Advisor, and could be supported by a service plan. The PowerLogic DVR is designed to reduce voltage sags on power lines that cater to sensitive commercial and industrial equipments.
