Description of the system
The 2-pole ATS-16 A is a two-way, single phase automatic switch powered by two independent synchro-
nous or asynchronous AC power supply sources.
The ATS-16 A makes a rapid switch from one source to the other in the event of a fault to the power supply
used to power the load.
One of the two sources can be designated as the preferred power supply, to which the ATS-16 A will trans-
fer the load. It remains there until different designations or faults require it to be switched to the other
source.
The ATS-16 A is fitted with a block diagram with LED indicators, capable of providing all the information
concerning equipment operation status, together with the power source priority selection button BP2
needed to enable trained operators to make full use of the apparatus.
