INDUSTRIAL RECTIFIER AND BATTERY CHARGER (SPS-RC)
Battery Chargers are robust, industrial rectifier, battery charging system and DC system. Based on proven technology (with 30 years of experience) to provide reliable dc output and battery charging capabilities for all types of batteries including lead acid, VRLA and NI-CAD batteries. These are available in standard system. Configured or customized system and comply with precise specifications. These industrial system are available in natural cooled as well as forced cooled designs and have quick transient response under line and load variation. These types of battery equipments are used in Power Generation Plants, Electricity sub-stations, Captive Power Plants, Telecom, Generator Starting and other Control and Instrumentation applications.
