Chint TNS1-9 AC voltage stabilizer

The Chint TNS1-9, as a three-phase fully automatic AC voltage stabilizer, is widely applied in various fields such as industry, commerce, and healthcare. The following is an in-depth analysis combining the latest market trends and technical details:

I. Core Technical Parameters and Performance Upgrades

1. Voltage Adaptability

- **Input Range**: 280V~430V (three-phase four-wire system), supporting a voltage fluctuation of ±20%, and can be adapted to the mainstream power grid standards in China, Europe, etc. However, it should be noted that the standard three-phase voltage in the United States is 208V or 240V. Direct use may require an additional step-down transformer or a customized model (such as the 110V/208V version of TNS1-9). YouTube：https://youtube.com/shorts/drW15hgAM3I 

- **Output Precision**: 380V±4%, using a high-precision servo motor to drive the carbon brush adjustment, with a response time of ≤6 seconds (when the input phase voltage changes by 20V).

2. Energy Efficiency and Environmental Protection

- **Efficiency**: ≥95%, in line with China's GB 20052-2020 first-level energy efficiency standard.

- **Certification**: Passed the CCC certification, and some models have passed the UL certification (the specific batch needs to be confirmed), meeting the market access requirements in North America.

II. Market Trends and Alternative Solutions in 2025

1. Product Iteration  Chint NXR series thermal overload relays price

- Chint launched a new generation of NPS3 series precision purification voltage stabilizers in 2025. Compared with the TNS1-9, it has added an intelligent monitoring module, supporting RS485 communication and remote control, which is suitable for high-reliability scenarios such as data centers.

- For the US market, Chint launched the North American version of TNS1-9 (input 208V/240V), which has passed the UL certification and can be directly connected to the local power grid.

2. Price and Channels  CHINT contactor price

- **Domestic Price**: Approximately CNY 1,945 to CNY 3,100 (including VAT), and the specific price may fluctuate depending on the purchase quantity and promotional activities.

- **International Procurement**: Through Chint's overseas subsidiaries or authorized dealers (such as Hebei China Electric), Whatsapp: 0086-138112554350

III. Application Scenarios and Typical Cases

1. Industrial Scenarios  CHINT surge protector price

- **Semiconductor Manufacturing**: A certain chip factory uses the TNS1-9 to supply power to the lithography machine, ensuring that the voltage fluctuation is ≤1%, and avoiding the scrapping of wafers caused by unstable voltage.

- **New Energy Field**: In the supporting of photovoltaic inverters, the TNS1-9 can stabilize the 380V output and ensure the stability of grid-connected equipment.

2. Commercial and Medical Scenarios

- **Hotel Power Distribution**: A five-star hotel uses the TNS1-9 to supply power to the central air conditioning system, reducing the failure shutdown of the compressor caused by voltage fluctuations.

- **Medical Imaging Equipment**: After the CT machine in the hospital uses the TNS1-9, the image clarity is improved, and the equipment failure rate is reduced by 40%.

 IV. Installation and Operation and Maintenance Key Points

1. Environmental Requirements

- Installation Environment Temperature: -5°C~+40°C, relative humidity ≤90%.

- Ventilation Requirements: It is necessary to reserve a heat dissipation space of ≥10cm to avoid dust accumulation.

2. Troubleshooting

- **Abnormal Output Voltage**: Check the wear condition of the carbon brush (it is recommended to maintain it annually), or replace the control circuit board.

- **Overload Protection**: If the overload protection is frequently triggered, it is necessary to confirm whether the total load power exceeds 9KVA, or check for any short circuits.

V. After-sales Service and Policies

1. Warranty Policy

- Domestic: The whole machine is under warranty for 1 year, and the core components (such as voltage regulators and servo motors) are under warranty for 2 years.

- International: Products purchased through authorized dealers can enjoy local after-sales service, and the specific terms need to be confirmed with the dealer.

2. Technical Support

- Chint's official website provides the electronic manual and circuit diagram of the TNS1-9, and supports online consultation.

- Overseas users can contact Hebei China Electric to obtain multilingual technical documents.

VI. Selection Suggestions and Alternative Solutions

1. Capacity Selection

- If the load power is close to 9KVA, it is recommended to choose the 15KVA model (such as TNS1-15), with a 20% redundancy reserved.

- For non-linear loads (such as frequency converters and UPS), power factor compensation needs to be considered, and it is recommended to be equipped with the Chint NPS3 series voltage stabilizers.

2. Intelligent Upgrade

- It can be equipped with Chint's "Taiwuyou" intelligent operation and maintenance platform to achieve remote monitoring, fault warning, and data analysis, and improve the operation and maintenance efficiency.

VII. Adaptation Guide for the US Market

1. Voltage Conversion Solutions

- **Solution 1**: Use a step-down transformer (such as 480V/208V) to step down the input voltage to 208V, and then connect it to the TNS1-9.

- **Solution 2**: Directly purchase the North American version of Chint TNS1-9 (input 208V/240V), and it is necessary to confirm the delivery cycle with the supplier in advance.

2. Certification and Compliance

- Ensure that the product has passed the UL certification (UL File No. E356782) and meets the requirements of the NEC (National Electrical Code).

VIII. Typical User Feedback

- **Positive Comment**: "The TNS1-9 performs stably under extreme voltage fluctuations and protects our production equipment."

- **Suggestion for Improvement**: "I hope to add an intelligent communication interface for convenient remote monitoring."
