AUTOMATIC TRANSFER SWITCH CONTROLLER

DESCRIPTION

Automatic transfer switch controller are installed and work two source of power supply or one main source of supply and a backup power generator. Automatic transfer switch controller serve to monitor additional alternate supply source due to disproportionate of energy releases and help you reduce complexity in terms of hardware, spacing, and component cost for new builds and retrofits. This is possible, because of our configurable software allows these applications to run from one controller:
