This technology is called double conversion because the electricity supplied by the raw network is converted twice before feeding the computer: a first time in direct current via the rectifier.
A second time in alternating current by the inverter.
In the event of a power failure, the battery supplies power to the UPS.
The bypass is used to transfer power from the computer to the network in the event of an overload or failure of the inverter.
This technology protects against: The cuts and micro-cuts Parasites Frequency variations Tension hollows Surges, lightning according to the manufacturers.
All our inverters of this technology incorporate a lightning protection.
