How to Select BYSON ATS?

Choosing the right BYSON ATS (Dual Power Automatic Transfer Switch) requires consideration of parameters, application requirements, safety standards, and brand-specific features. Below is a step-by-step guide to help you make the best selection.

How to Choose the Right Dual Power Automatic Transfer Switch (ATS):

When the main power source fails, every second counts. A Dual Power Automatic Transfer Switch (ATS) is the device that makes sure your equipment never stays in the dark for long. It automatically switches from the main power supply to a backup source—like a generator or a second utility line—when it detects a voltage drop or outage.

In simple terms, an ATS is an intelligent switching device. It constantly monitors your main power supply. If the voltage falls below a preset level or disappears completely, the ATS sends a start signal to your backup generator or connects to a secondary utility source. Once the main power returns and becomes stable, the ATS switches back automatically.

There is no manual intervention needed. This makes ATS units essential for any business or facility that cannot tolerate long interruptions—even a few minutes of downtime can be costly.

This guide walks you through what really matters when selecting a dual power ATS, so you can avoid common mistakes and get the best value for your project.

Key Benefits of a Quality ATS:

• Uninterrupted Operation – Critical systems stay online during blackouts or brownouts.

• Safety – Prevents back-feed that could harm utility workers or damage equipment.

• Reduced Downtime – Switching happens in seconds, sometimes even faster.

• Equipment Protection – Many ATS units include voltage and frequency monitoring to ensure clean power before transferring.

Common Applications:

You will find dual power automatic transfer switches in:

• Commercial buildings – To keep elevators, lighting, and security systems running.

• Healthcare facilities – Life-support equipment and refrigeration for medicine.

• Data centers and IT rooms – Servers cannot afford sudden shutdowns.

• Telecommunication stations – Cell towers need backup power for network reliability.

• Industrial plants – Production lines and ventilation systems.

• Residential complexes – High-end apartments with shared generators or solar-battery systems.

How to Choose BYSON ATS:

1. Rated Current

Match the ATS to your load. A common mistake is buying a switch that is too small. Check your full load current—not just the running current but also inrush current from motors or transformers. Standard ratings include 32A, 63A, 100A, 125A, up to 630A or higher for industrial use.

2. Poles Number

• 2P – Switches both live conductors (phase and neutral). Suitable for single-phase systems.

• 3P – Switches three phases only. Neutral is solidly connected.

• 4P – Switches three phases plus neutral. Required when you have multiple power sources with separate grounding systems.

3. Switching Speed (Transfer Time)

Some applications can tolerate 1–2 seconds. Others need sub-second switching. For computers, medical devices, and precision controls, look for fast transfer times, usually below 100 milliseconds.

4. Voltage Compatibility

Make sure the ATS matches your system voltage (110V, 220V, 380V, 400V, etc.) and frequency (50Hz or 60Hz). Some units are programmable for different voltage ranges.

5. Type of Load

Is your load resistive (lights, heaters) or inductive (motors, compressors)? Inductive loads require higher breaking capacity and sometimes additional protection. A good ATS will specify its suitability for motor loads.

6. Verify Compliance & Certifications

Ensure the BYSON ATSmeets:

• IEC 60947-6-1

• Regional certifications: CE, CCC

Conclusion:

A dual power automatic transfer switch (ATS) is not the most glamorous part of an electrical system, but it is one of the most important. Focus on the basics: current rating, poles, switching speed, and certifications. Once those are clear, evaluate brands based on real-world availability, support, and value for volume orders. If you are planning a project and want reliable ATS units at fair prices, BYSON is ready to help.
