Main highlights

WIDE RANGE OF APPLICATIONS: ATS is widely used in power system that require continuous and stable power supply, including commercial and industrial buildings, facilities, data centers, and communication base stations

FLEXIBLE SETTINGS: This three phase automatic transfer switch enables you to freely prioritize mains power, generator, and inverter. You can set the voltage threshold for switching, so automatically switch when there is under voltage or over voltage. The switch speed can also be set within the range of 1s to 600s, with a default of 30s

AUTOMATIC TRANSFER FUNCTION: When the main power supply fail or the voltage is abnormal, the ATS automatically transfer the load from the main power supply to the standby power supply to ensure uninterrupted power supply. Priority is L1>L2>L3. ATS ensure smooth switching between the primary and backup power supplies, preventing power fluctuations or interference.

MANUAL MODE: When using the manual mode, the left switch of the power transfer switch is placed in the Manual position. If power I is selected, manually operate the handle on the right to set the switch to the I position, and the IU(green light) will light up. If power II is selected, please manually operate the right handle to set the switch to the II position. The IU(red light) will light up

AUTOMATIC MODE: When using the automatic mode, the left switch of the mini ATS is set to the Auto position, and the right handle is set to the I position. When the common power supply I is normal, the IU(green light) remains constantly on. When the common power supply I is abnormal, the IU(green light) goes out and switches to the automatic power supply II within 20ms, and the IIU(red light) turns on.

APPLICABLE SCENARIO: The input end of the automatic generator transfer switch can be connected to 1 neutral wire(N) and 1 live wire(L), specially designed for household rail installation, specifically for PZ30 distribution boxes, suitable for 50/60Hz dual power grids, suitable for indoor and outdoor generators.
