AUTOMATIC TRANFER SWITCH CONTROLLERS

What is an automatic transfer switch controller?

ATL20 and ATL30 are devices developed and designed to control and supervise the automatic or manual transfer of a utility from a main power supply source to a stand-by.
Both devices include all the necessary features to supervise and control power supply sources, composed by energy distribution systems or generating sets and the relative transfer equipment, such as contactors, motorised circuit breakers and changeover switches.
The utility changeover from one power source to the other, can be automatic or manual. The automatic transfer is carried out whenever conditions predefined by the user take place, for example:
-  Power supply is not available or switched off
-  Power supply source not respecting programmed limits
-  Need to have a very reliable power source
-  Need to use the most economical power source.
ATL20 and ATL30 have a dual supply circuit, one in DC and the other in AC; this consents to exclude the device from being switched off should one of the two voltages lack and to always provide for the transfer between the priority and standby sources.
