Online Double Conversion UPS Systems
An Uninterruptible Power Supply using true online double conversion technology provides the highest level of power protection available. The UPS converts the 230 VAC input AC mains supply to DC power which is then used to charge the battery. The DC voltage is then fed through an inverter stage which reconstructs the 230VAC mains output. This results in a supply that will be completely free from any mains born interference such as spikes and voltage variations. Online UPS are able to withstand large fluctuations on the input voltage before transferring to a battery power thus eliminating unnecessary battery discharges. Upon mains failure transfer to battery power is seamless with no break to your power supply
