Transfer Switches

Alpha Power Systems has a range of automatic or manual transfer switches which can be used for transferring the input power among different sources. Our swtiches can complete a transfer automatically and rapidly within micro-seconds to ensure the input sources are stably converted from one to another without any changes to the output loads.
