Our company, Adroit Power Systems India Pvt. Ltd. is a manufacturer of Delta Online UPS and industrial online UPS. In comparison to offline UPS system, the design of this system is much more complex. It's inverter supplies power continuously to the critical load. In overload conditions, mains power is directed to the load by the static bypass switch. Noise, surge voltage, transient voltage or any other disturbances can not affect the load when using this system. The benefits of Online UPS are load & main supply are isolated, better regulation of voltage and no transfer time. This system is mainly used with medical equipment.
