The technically advanced Smart Pure Sine Wave UPS operates on mains and supplies power while charging the battery when Mains supply is available. In case of a power outage, Smart transfers the entire load to its optimally charged battery and supplies high quality AC power.
Apart from the highest quality components and engineering, what makes Smart special is the inbuilt stabilizer and charger. With Smart there is no need to purchase an additional voltage stabilizer, or a charger for charge recovery in case the battery is exhausted. This is why it is becoming the most popular sine-wave UPS in the market.
