    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.

    In this video, it will show how ATO 4-pole automatic transfer switch changeover between the mains and standby power supplies in the manual & auto mode.

    Some question of auto transfer switch data
    Hope you are doing well.
    We’ve purchased a bulk quality of ATO for couple of ongoing projects and there is an query from our end customer about the input supply rating.

    The voltage of power supply can not exceed 400v, the voltage of 440v is too high.
    We think that the voltage is too high and the internal relay has burned out.
    Works flawlessly
    This ATC works perfectly well with my project. The switch over is very fast with nothing going off. A very good device!

    No, our ATS max operating voltage is 400V.
    Great ATS transfer switch
    Got a 4-pole transfer switch for my small generator with 40 Amp rating. As I like doing some arduino, It is simple to install and use. It works both in manual and automatic mode. Great product.

    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.

    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.
