The PowerLogic DVR series offer to industry a solution to regulate voltage and restore Sags. This Low Voltage - Dynamic Voltage Restorer eliminates three phase and single-phase sags and regulate plus-minus 20 % voltage continuously. The PowerLogic DVR system is a IGBT based electronic, and a flexible compensator that injects and absorbs energy. It mitigates and eliminates the effect of electrical disturbances to offer a stable voltage with a fast response. The topology of the system allows continuous regulation without using energy storage such as battery or capacitors. This DVR systems require a mandatory additional Manual Bypass cabinet, rated at 2000 A, and two secondary units. Protection of sensitive loads in power distribution and transmission systems against voltage distortions. This apparatus do have the capacity to correct up to -50 % sags for 30 seconds at 400 VAC, 660 kVA rated power. 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 apparatus 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.
