Power supply solutions for ATS controller
The problem:
During the transfer from the source 1 to the source 2 and vice versa the auxiliary power supply must be selected from the most reliable source available.

The solutions:
“Traditional”: a wired logic with two or more relays to select the available source
DC supply: available with ATL610, ATL800, ATL900. The battery or the UPS connected provides safe and continuous control during the changeover from source 1 to source 2. The automatic transfer switch controller does not switch off in the event of instability both sources
Dual power supply module ATLDPS1: a single and very compact device select, with a digital control, the best source to use.
