ATS / STS Systems

ATS (Automatic Transfer Switch) and STS (Static Transfer Switch) systems ensure uninterrupted power continuity in data centers by enabling automatic and secure switching between different power sources. These systems transfer power between the grid, generator, and UPS lines within milliseconds, maintaining operational continuity.

At ERFA Information Technologies, we provide redundant and monitorable ATS/STS solutions equipped with high-speed transfer technologies. Each system is configured with both electrical and software security layers to ensure critical loads are continuously powered without interruption. All processes from installation to commissioning are managed with an engineering approach in accordance with international standards.

Operating Principle:

Uninterrupted power transfer through automatic and static transfer architecture

Performance:

Load continuity with millisecond-level transfer times

Safety:

Dual-source configuration with isolated circuit protection

Control Infrastructure:

Intelligent microcontroller-based monitoring and status reporting

Redundancy:

Maximum system continuity with N+1 topology

Application Area:

Data centers, critical facilities, and telecom infrastructures

ATS systems provide automatic transfer between the grid and generator sources; in the event of a power outage, loads are seamlessly switched to backup sources. STS systems perform millisecond-level static transfers between UPS outputs, ensuring sensitive IT equipment remains operational without interruption. ERFA’s ATS/STS solutions are equipped with advanced monitoring modules and remote alarm systems. System performance, power quality, voltage deviations, and phase shifts are monitored in real time.

“Power outages happen instantly; engineering ensures continuity.”

All ATS/STS systems are verified before commissioning with load tests, transfer time analysis, and thermal balance measurements. Post-installation maintenance plans and DCIM integration allow continuous performance monitoring, ensuring data centers meet the highest standards of power continuity, safety, and energy efficiency.


In the era of digital transformation, we design data center infrastructures focused on high availability and sustainability, enabling organizations to move confidently into the future.
