Description
The controller of the intelligent automatic transfer switch (ATS) simultaneously detects the phase voltages of the two power supplies. When the power supply voltage is lower than 70-80% of the rated voltage, after comparison and judgment, the controller directly sends the detection result to the LCD display on the controller panel. And after a delay through the delay circuit, a switching command is sent to the electrical control mechanism.
For self-switching and self-resuming, in the automatic control state, when the power supply is normal, it should be powered by the common power supply. When the common power supply malfunctions (any phase undervoltage or phase loss occurs), it will automatically switch to the backup power supply after a set delay. When the common power supply returns to normal, after the set delay, it will automatically return to the common power supply. If the power supply in use malfunctions, the controller will emit an alarm sound to prompt the operator to repair it in time and ensure that the power supply remains in a hot backup state for a long time. This alarm sound can be turned off through the operation button on the controller panel.
ApplicationsLJQ2 series Intelligent automatic transfer switch (ATS) are widely used in important places such as hospitals, shopping malls, banks, chemical plants, metallurgy, high-rise buildings and military facilities where power outages are not allowed, as an important electrical device to ensure continuous power supply.
