ATS Selection for Data Centers: A Brief Overview

Automatic Transfer Switches (ATS) are vital components in data centers, ensuring seamless power supply during outages. Here's a quick rundown of ATS types commonly used in data centers:


1. Open Transition ATS:
- Disconnects from the primary source before connecting to the backup generator during a power outage.
- Brief interruption in power supply during transfer.
- Suitable for non-critical loads but may not be ideal for sensitive equipment.

2. Closed Transition ATS:
- Offers a smooth, uninterrupted transfer between primary source and backup generator.
- Both sources are momentarily connected, minimizing any disturbances during the switch.
- Ideal for critical applications and sensitive equipment.

3. Soft Loading Transfer Switch:
- Manages gradual power transfers during ATS operations.
- Prevents sudden power surges, protecting delicate equipment.
- Ensures a controlled and smooth transition, especially useful for sensitive applications.

4. Bypass Installation ATS:
- Enables maintenance or repair without interrupting power to connected loads.
- Provides an alternative power path, bypassing the ATS during maintenance.
- Ensures constant uptime and minimal downtime for critical data center operations.

Selecting the right ATS depends on factors such as equipment sensitivity, tolerance for power interruptions, and maintenance requirements. Choosing the appropriate ATS will enhance data center resilience, customer satisfaction, and overall business continuity during power events.
