[Product Description]

An uninterruptible switch that can switch the load while two power sources are being synchronized by a switch used for switching between a commercial power source and a standby power source in a low voltage switchboard

In case of general ATS, momentary power failure may occur, but in case of CTTS, both power sources are supplied at the same time to prevent power failure.

In the following situations, uninterrupted switch will be turned on to protect the load

   ∙ Power outage

   ∙ Power is normal but the momentary power failure occurs due to natural disaster

   ∙ When power is returned and re-transferred from the generator to the power

   ∙ Power is normal, during generator testing or other equipments

It is used mainly in expensive computer equipments in hospitals, computer centers, airports, military facilities, or facilities with important computer equipments.
