An online double conversion UPS is the best choice for this requirement as it provides continuous power supply to the load from its batteries and the electrical supply is only used to recharge the batteries. In an online double conversion UPS, the incoming AC power is first rectified to DC, then inverted back to AC to supply power to the load, and then rectified and inverted again to charge the batteries. This process ensures that the load is always powered by the batteries, providing stable and uninterrupted power supply.
