Case Study

Data Center in Singapore Ensures 99.999% Uptime

A leading data center in Singapore faced intermittent power failures that risked service level agreements. They integrated our ATS controllers with their dual power supply system. The controllers' fast transfer mechanism ensured seamless switching to backup generators within 80ms, well below the critical threshold. Over a 12-month period, the data center achieved 99.999% uptime, preventing an estimated $2 million in potential downtime costs. Our controllers also provided remote monitoring capabilities, allowing engineers to perform diagnostics without on-site visits, reducing response time by 60%. The project's success led to a contract extension and recommendations to three other data centers in the region.

Hospital in Saudi Arabia Enhances Patient Safety

A major hospital in Riyadh required an ATS controller that could handle critical life-support equipment during grid outages. Our ATS controllers, with their robust construction and precise voltage sensing, were installed in the main power distribution system. When the primary utility failed, the controller initiated generator startup within 5 seconds and completed transfer in under 150ms, ensuring uninterrupted power to operating rooms and ICU units. Over two years, the hospital reported zero critical incidents related to power supply. The controllers' self-testing features allowed regular maintenance without shutting down power, increasing operational efficiency by 25%. This case underscores the reliability of our ATS controllers in demanding healthcare environments.

Solar Farm in Australia Optimizes Energy Switching

A renewable energy farm in Australia integrated our ATS controllers to manage the transition between solar, battery storage, and grid supply. The controllers' advanced logic enabled smooth synchronization and load balancing, preventing reverse power flow that could damage the grid. During a grid disturbance, the controller switched to off-grid mode within 100ms, maintaining stable power supply to irrigation systems. This resulted in a 98% reduction in equipment damage caused by power surges. The farm also benefited from our controllers' communication capabilities, allowing seamless integration with SCADA systems for centralized monitoring. This project highlights the versatility of our ATS controllers for renewable energy applications.

ZHNYU ELECTRIC, with a legacy of precision engineering since 1992, has emerged as a global leader in the design and production of ATS controllers. These controllers form the intelligent heart of our dual power automatic transfer switches (ATS), enabling automatic or manual switching between primary and backup power sources. This capability is indispensable in sectors where power continuity is critical, including data centers, hospitals, industrial automation, and infrastructure projects. Our ATS controllers are not mere switching devices; they are comprehensive solutions that enhance system resilience and protect valuable assets from power disruptions.

Frequently Asked Questions

What is an ATS controller and how does it work?

An ATS controller (Automatic Transfer Switch Controller) is a device that monitors the power supply from the primary source (usually the utility) and, when it fails, automatically initiates a transfer to a backup source (like a generator). It does this by continuously sensing voltage and frequency. If the primary power drops below a preset threshold for a specified time, the controller sends a signal to start the generator, then switches the load to the backup source via contactors or switches.
With open transition (break-before-make), the load is disconnected from the primary source before being connected to the backup, causing a brief interruption. Closed transition (make-before-break) overlaps the two sources momentarily, allowing zero interruption during transfer, but requires both sources to be in sync. Closed transition is ideal for critical loads like data centers.
Yes, our controllers are highly configurable. We offer models that support various nominal voltages (e.g., 230V, 480V, 600V) and frequencies (50Hz or 60Hz). Furthermore, you can set parameters such as under-voltage and over-voltage thresholds, transfer delay times, and generator start/stop commands.
Regular maintenance is minimal but important. We recommend periodic functional tests (e.g., monthly) using the test mode. Our controllers often have self-diagnostic indicators and log event histories. In case of failure, the controller may display error codes that you can look up in the manual. For remote troubleshooting, our controllers can be integrated with software that provides alerts.

Customer Testimonials

Michael Thompson
Exceptional reliability for our data center

We integrated ZHNYU ELECTRIC's ATS controllers into our power infrastructure, and the results have been outstanding. The switchover time is incredibly fast, typically under 100 milliseconds, which has eliminated flicker and downtime. In the past six months, we've had zero power-related incidents, and remote monitoring has simplified our operations.

Sarah Mitchell
Tailored solution for renewable integration

Our solar plant needed a controller that could handle storm fluctuations between solar and grid. ZHNYU ELECTRIC's ATS controllers did exactly that. The closed transition feature ensures stable synchronization, and we've seen a 95% reduction in power surges affecting our inverters. Their team provided excellent technical support during installation.

Our ATS controllers are built to deliver

Our ATS controllers are built to deliver

With a mean time between failures (MTBF) exceeding 500,000 hours, they ensure continuous operation in critical environments. The transfer process is optimized to take less than one second, often under 100ms, meeting stringent power quality standards. In a recent hospital installation, our controllers executed over 40,000 successful transfers without a single failure over three years. This reliability is achieved through premium components and meticulous testing, reducing the risk of power interruptions that could cause financial losses or safety hazards.
Advanced Protection and Diagnostics

Advanced Protection and Diagnostics

Our controllers come equipped with advanced protection features, including over/under voltage, frequency, and phase reversal detection. They also monitor load current to prevent overloads. Built-in self-test routines can be scheduled to check the controller's health without disrupting operations. Furthermore, the controllers log the last 100 events, aiding in diagnostics and system analysis. For example, an industrial plant diagnosed a recurring nuisance trip using the event log, which we helped resolve, resulting in a 60% reduction in unplanned downtime and preventing equipment damage.
