FEATURES
The AST 3225 AutoStart Transfer Switch System provides an automatic transfer of an electrical load to a stand-by power supply in the event of a drop, or loss of voltage, on any or all phases of the normal power supply. Upon the restoration of normal power, the electrical load is automatically re-transferred to the normal power supply. The base unit comes complete with an ES-53 Controller, which starts the engine automatically and provides the necessary timing functions. All time delays are built into the ES-53, and are fixed to simplify installation, start-up, and field servicing.
