Battery Chargers for Nuclear Plants Download PDF Data Sheet Solidstate Controls, Inc. (SCI) has designed, manufactured and maintained hundreds of safety related, (1E) and non-safety, yet essential, Battery Chargers in Nuclear generating facilities around the globe. Each application requires a unique set of solutions in which SCI will help create the optimum Battery Charger System for your plant. SCI Battery Chargers are thyristor-based systems designed for high-efficiency conversion (>90%) of commercial AC power to DC power, for charging station type batteries. They are also compatible with our inverter systems to be used as an Uninterruptible Power System (UPS) as a float system, or as stand alone Charger for DC only applications. All models are equally compatible with all lead acid type batteries including, lead calcium & antimony, nickel cadmium, or valve regulated for station DC systems. A dry type isolation transformer is used to isolate the DC output from the AC input and to provide the proper voltage for the rectification process. Standard output ripple filter, 2% with battery connected, is provided. Optional low ripple and battery eliminator low ripple options are available. The Charger can also be utilized, and packaged, with incorporation of a blocking diode, as a regulated rectifier package in SCI inverters. DC Output Isolated from AC Input Output Filter Battery Overcharge Protection Wide Range of Options Seismic and Environmental Qualifications to meet your 1E Safety Related Applications Replacement in existing Charger footprints are accommodated.
