Case Study

Ensuring Uninterrupted Power for Solar Farms in Germany

A leading solar energy provider in Germany faced frequent grid fluctuations, causing inverters to trip and halting energy export. ZHNYU provided a 3 phase ATS with a transfer time of 60ms, integrated into their 1.5MW PV station. The ATS intelligently switches between the main grid and battery storage during outages. Result: The system achieved 99.9% uptime, increasing annual energy yield by 15% and saving €50,000 in potential lost production.

Enhancing Redundancy for Hospital Power Systems in Brazil

A 300-bed hospital in São Paulo required a dependable backup power source to ensure patient safety during blackouts. We installed dual 3 phase ATS units (400A) to manage the load between utility and two diesel generators. The ATS units performed automatic load testing weekly, preventing generator failure. After installation, the hospital reported zero critical equipment shutdown during power interruptions over 12 months, improving patient care and meeting strict healthcare regulations.

Optimizing Production Line Efficiency in a Chinese Automotive Plant

An automotive manufacturer in Shanghai experienced costly downtime due to manual transfer between main and standby power. They integrated our 3 phase ATS (630A) into their assembly line's power distribution system. The ATS's programmable logic allows sequence control linking with PLC. Consequently, production stoppages dropped by 85%, saving approximately $200,000 annually. The project showcased our ATS's ability to handle high inrush currents and its wide frequency tolerance (50/60Hz), making it ideal for dynamic industrial environments.

ZHNYU ELECTRIC, with over three decades of excellence, sets the benchmark for 3 phase ATS manufacturing. Our journey began in 1992 in China's dynamic industrial heartland, and we have since grown into an ISO9001-certified enterprise, exporting to more than 60 countries. Our state-of-the-art facility, covering 10,000 square meters, is home to 100+ specialized production machines, including CNC winding, laser welding for contacts, and automated test benches. Each 3 phase ATS undergoes a 72-hour burn-in test under simulated load conditions to ensure infallible performance. We employ a four-stage quality control process: raw material inspection, in-process monitoring, final parameter testing, and packaging verification. This meticulous approach yields a defect rate of less than 0.1%, a figure we are continuously improving. Our R&D team, comprising 15 senior engineers with an average of 12 years of field experience, works closely with clients to customize ATS solutions. For instance, we developed a marine-grade version with corrosion-resistant coatings for offshore oil platforms. Our manufacturing flexibility allows us to produce ATS units from 16A to 6300A, catering to low-voltage switchgear needs.

Frequently Asked Questions

What is a 3 Phase ATS and how does it work?

A 3 Phase ATS automatically switches the power supply between primary and backup sources, such as the mains and a generator. It monitors the availability and quality of power, and when an outage or abnormal condition is detected, it transfers the load to the secondary source. ZHNYU's 3 Phase ATS uses microcontroller-based logic that continuously measures voltage and frequency, ensuring a transfer time of less than 100ms for most models.
3 Phase ATS are essential in any setting that demands high reliability and continuous operation. Typical applications include hospitals, data centers, industrial plants, commercial buildings, and renewable energy systems. For example, in a data center, an ATS ensures that servers continue to run without interruption. In a photovoltaic system, it manages the transition between grid and battery storage.
Selecting the right ATS depends on several factors: the load capacity (in amperes), the system voltage (e.g., 400V), the type of loads (inductive, lighting, etc.), and the desired transfer time. At ZHNYU, we help you calculate the required current and choose between open transition, closed transition, or delayed transition. We also consider harmonic distortion and environmental conditions.
Our 3 phase ATS products are certified with ISO9001 for manufacturing quality, CE for compliance with European safety standards, and CCC for the Chinese market. Additionally, they meet RoHS requirements, ensuring they are free from hazardous substances. For global clients, these certifications guarantee that our ATS units meet rigorous international standards for safety and performance.

Ultra-Fast Transfer for Zero Downtime

Ultra-Fast Transfer for Zero Downtime

In critical processes, even a second of power loss can be catastrophic. ZHNYU's 3 Phase ATS is engineered with a high-speed switching mechanism that transfers the load in under 80ms—fifty times faster than the blink of an eye. This near-instantaneous changeover is achieved through advanced solid-state sensing and a double-throw contactor design that ensures arc suppression. For industries like semiconductor fabrication, where micro-interruptions cause product loss, this speed translates into millions saved annually. Our ATS is equipped with voltage and frequency monitoring on both sources, automatically selecting the healthier supply. Additionally, closed transition models offer a brief paralleling period to avoid phase shift, making them ideal for sensitive electronic equipment. The reliability of this system is backed by rigorous testing, including 10,000 automatic transfer cycles without failure.
