Custom DLQ5 Dual power automatic transfer switch Manufacturer, Exporters

An automatic transfer switch (ATS) is an electrical device that automatically switches the load to a backup power source when the main power supply is interrupted. It ensures rapid power restoration after a power outage and is commonly found in critical locations with high power continuity requirements, such as hospitals, airports, data centers, and high-rise buildings. These switches typically include voltage detection, electrical and mechanical interlocking functions, and protection against overvoltage, undervoltage, and phase loss.

Product Description

Operating Principle

Power Supply Detection

The switch continuously monitors the voltage of the main power supply (common power source).

Fault Diagnosis

When a fault is detected in the main power supply (e.g., power outage, undervoltage, phase loss), the switch automatically disconnects from the main power supply.

Switching to Backup Power

Subsequently, it quickly connects to a backup power source (e.g., a generator or another power grid), switching the power supply to the load.

Recovery Operation

When the main power supply returns to normal, the switch will switch the load back to the main power supply and disconnect from the backup power supply.

Main Functions and Features

High degree of automation: Equipped with automatic switching function, requiring no manual intervention and ensuring continuous power supply.

Frequently Asked Questions

How fast does the automatic transfer switch operate?

The switch features fast switching speeds, with mechanical structures typically requiring over 100 milliseconds to minimize equipment downtime during power outages.

Does the system require manual intervention when power fails?

No, the device is equipped with a high degree of automation. It detects faults and switches to backup power automatically without requiring manual intervention.

How does the switch ensure safety during the transfer?

It utilizes reliable mechanical and electrical interlocking functions to prevent two circuit breakers from closing at the same time, which effectively avoids short-circuit accidents.

What happens when the main power supply is restored?

Once the main power supply returns to normal, the switch performs a recovery operation, automatically switching the load back to the main supply and disconnecting the backup source.

Can this switch protect against voltage fluctuations?

Yes, the switch provides automatic protection and switching for various fault conditions, including overvoltage, undervoltage, and phase loss.

Does it support remote monitoring?

Yes, many of our intelligent control models support the "four remote" functions: remote control, remote control, telemetry, and remote signaling.
