Dual Power Automatic Transfer Switch ATS / Low-Voltage Primary Components

1. Product Overview

This product is an automatic power switching assembly designed for low-voltage power distribution systems requiring continuous power supply. It integrates a dual power automatic transfer switch ATS and other essential low-voltage primary components inside a dual power distribution cabinet or emergency power panel. The assembly automatically switches the load between the main power source and the standby power source to maintain power supply continuity during power failure, voltage abnormality or phase loss.

2. Core Components

• Dual Power Automatic Transfer Switch ATS

Automatically detects power supply status and switches the load circuit between main power and standby power.

• Controller

Monitors voltage, phase sequence and power failure signals, and sends switching commands.

• Switching Mechanism

Performs automatic or manual transfer between the two power sources.

• Main Power Source Terminal

Connects to the normal power supply from the grid or main distribution system.

• Standby Power Source Terminal

Connects to backup power supply such as generator, UPS or standby feeder.

• Outgoing Terminal

Connects to critical loads that require continuous power supply.

• Mechanical Interlock

Prevents simultaneous connection of the main power source and the standby power source.
