Smart Intelligent Wcq2g ATS Automatic Transfer Switch 1p 2p 3p 4p

The smart version adds an electronic controller that continuously monitors both sources, makes decisions based on programmable thresholds, and reports its status. This goes beyond a simple motorized changeover by offering self-diagnosis, adjustable parameters, and optional remote communication for unattended operation.

The display indicates which source is live, whether the load is on the main or backup supply, voltage/frequency values, and any fault or alarm conditions. It lets the operator confirm the transfer state at a glance without measuring each circuit manually.

Yes. The controller is programmable, allowing you to set undervoltage/overvoltage trip levels, transfer delay, retransfer delay, and generator warm-up/cool-down timing. This lets you tailor behavior to the load and the tolerance of your backup source.

Select versions include communication ports for remote monitoring and control, which supports unattended substations and building management systems. Through these interfaces you can read source status, transfer events, and alarms from a central supervisory system.

The controller measures voltage (and frequency where applicable) on both inputs in real time. If one source drifts outside the configured band while the other is healthy, it initiates a controlled transfer according to the programmed logic and delays.

On main failure, the controller starts the generator via a relay output, waits until its output is stable, then closes the backup path. When the main supply is restored and remains stable for the retransfer delay, it transfers back and shuts the generator down after a cool-down period.

The smart WCQ2G is offered in 1P, 2P, 3P, and 4P versions. Single-phase loads use 1P or 2P, while three-phase installations choose 3P (without neutral switching) or 4P (with neutral switching) depending on the earthing arrangement.

An emergency manual operation lets you operate the mechanism by hand for commissioning or in a power-loss control scenario. The device can also be set to manual mutual transfer between preferred and backup sources when automatic operation is not desired.

It is used in hospitals, commercial centers, airports, industrial plants, and residential communities where automatic, monitored backup power is required. It is especially suitable for installations that need remote supervision rather than a manned switchboard.

It is built to IEC/EN 60947-6-1 and GB/T 14048.11 for transfer switching equipment. These standards define the ratings, interlock requirements, and endurance tests that ensure safe, reliable transfer between two supplies.
