    Tips: What's dual power automatic transfer switch?
    The automatic transfer switch (ATS) is a switch to transfer between two power sources. It is constituted by one or several change-over switching equipment and other necessary apparatuses. It is used to detect the power circuit. In addition, it changes over one or several load circuits from one power supply to the other power supply.
    For the use of dual power automatic transfer switch, briefly, it is connected with one utility power and one backup power. When the utility power suddenly fails, it will be transfer to the backup power supply automatically through the ATS (at the small load, the backup power supply can be supplied by the generator) to enable the equipment to operate normally. The most common application is the elevator, fire protection and monitoring. The condition is the same to the UPS uninterruptible power supply of the bank. However, its backup is the battery set. It is used in some factories and mines or units with loads of class I category and class II category.

    Works as described.
    I bought this 63 amp ATS for switching between the solar and main power at my house. First I tested this ATS for several times before installation. Works as described.

    This switch works as advertised.
    This auto transfer switch is easy to install and operate according to the instruction, but it is a little expansive. Nevertheless, this switch works as advertised.
