Automatic Transfer Switch (ATS)
100A, 160A, 250A, 400A, 630A, 800A, 1000A, 1250A, 1600A, 2000A, 2500A, 3200A
Automatic Transfer Switch (ATS) is a cutting-edge electrical solution designed to seamlessly transition between dual power sources (main/backup), ensuring uninterrupted power supply to essential operations, thereby preventing costly production halts, critical data loss, or potential equipment damage caused by power outages.
- Core Functions
Automatic Switching - Instantly reacts when the primary power supply encounters issues (like power failures, undervoltage, overvoltage, etc.), automatically shifting to a reliable backup power solution (such as a generator, UPS, or secondary mains power).
Manual Priority Mode - Facilitates manual intervention for maintenance tasks or emergency situations, making operations more manageable.
Zero-Second Switching (Optional) - Select models offer seamless, instant switching, perfect for environments where uninterrupted power is crucial, such as data centers and medical equipment.
Efficiently uphold electrical safety standards and guarantee constant power availability in critical zones!
Intelligent Monitoring: Continuously monitors voltage and frequency, initiating an automatic switch if irregularities are detected.
High Reliability: Built with industrial-grade durability, designed for frequent use, withstanding over 10,000 operations.
Safety Protection: Offers robust overload and short circuit protection, complemented by an IP protection rating ideal for tough environments.
Flexible Control: Enables easy switching between automatic and manual modes for versatile control.

Robust Connecting Terminal (Extended Circuit Board Aging Test for 48 hours to ensure durability)
Advanced Fire Alarm Functionality of ATS
In the critical fire power supply system, the dual power automatic transfer switch (ATS) is designed not only for seamless automatic switching between primary and backup power sources but also incorporates an essential fire alarm linkage function. This ensures uninterrupted power to vital fire safety equipment such as smoke exhaust fans, fire pumps, and emergency lighting in the event of a fire. It also provides timely and accurate real-time feedback on power status to the fire control center.
Compulsory Power Switching - Even upon restoration of the primary power supply, the backup power system remains engaged until manually reset, preventing any accidental power loss during crucial fire extinguishing operations.
Exceptional Reliability - Features a mechanical/electronic dual interlock system to effectively prevent short circuits resulting from the parallel connection of dual power sources.
Rapid Response Mechanism - Ensures switching occurs in ≤ 1 second, with some critical load requirements being met in an impressive ≤ 0.2 seconds.
Intelligent Fire Signal Linkage - Capable of receiving signals from the fire control center to forcibly secure and lock the backup power supply.
Comprehensive Switch Structure Explanation:
1. Secure Electric Key Lock:This feature controls the internal controlling line power supply of the switch. When the electric lock is open, the switch can be operated both automatically and remotely. When closed, it allows manual operation using the handle only, ensuring security and control.
2. Ergonomic Operating Handle:For manual switch operation using the handle, it is essential that the electric lock remains closed to ensure safety and precision.
3. Durable Mechanic Padlock:During inspections, first turn the switch to the "0" position using the operating handle, then engage the padlock mechanism and secure the padlock. This action cuts off the internal controlling power supply of the switch, preventing any electrical position or manual operation, thereby ensuring safe inspection conditions.
4. Clear Position Indication:Provides a clear indication of the switch's operational state (I, 0, II), ensuring users are always informed of the current position.
Installation Instructions
Installation Guide for Dual Power Automatic Transfer Switch (ATS):
Installation Location: Select a dry, well-ventilated area for the installation, strategically positioned near both the main and backup power supply inlets. This ensures effortless operation and seamless maintenance access.
Wiring Specifications: Connect the main and backup power supplies to the ATS's input terminals, ensuring that the output terminals are connected to the load. Carefully distinguish the phase sequences (L1/L2/L3/N/PE) to maintain operational integrity.
Switching Test: Simulate a main power outage after activation, and verify that the automatic switching time remains within 1.5 seconds, ensuring the load remains continuously powered without interruption.
Safety Requirements: Ensure reliable grounding and match the shell protection level to the environmental conditions (e.g., IP40 for indoor settings). Comply with the GB/T 14048.11 standard to uphold safety and performance.
