Frequently Asked Questions (FAQ)

1. What is the input voltage range of the product?
The UPS systems are 200V±10%, which means it can operate stably under voltage fluctuations from 180V to 220V, adapting to the power grid voltage standards of different countries and regions.
This wide voltage range design allows the UPS to maintain stable output even when the power grid fluctuates significantly, reducing equipment failures due to unstable voltage.
Users should ensure the input voltage is within this range to guarantee stable operation and extend the life of the UPS.

2. How to conduct a load test for the UPS?
Load testing is an essential step in evaluating the performance of a UPS, which can be done by gradually increasing the load until it reaches the rated capacity.
During the test, closely monitor the UPS's output voltage, current, and temperature to ensure they are within normal limits.
Load testing helps users understand the UPS's performance under different load conditions, ensuring reliability in actual applications.

3. How does the cooling system of the product work?
The UPS systems features a redundant cooling fan system to maintain the device's temperature within a safe range even under high load conditions.
The cooling fan design effectively expels heat generated inside the device, preventing performance degradation or device damage due to overheating.
Users should regularly inspect the fan's operation and clean dust and debris from the fan and heat sinks to maintain good heat dissipation.

4. How can the UPS ensure stable output when the power grid is unstable?
The product is designed with a battery backup system that automatically switches to battery power mode when the power grid is unstable, ensuring continuous and stable output.
Users should regularly check the battery's condition to ensure it can provide sufficient power when needed.
By monitoring the UPS's status, users can detect potential issues early and take measures to prevent equipment failures due to power grid problems.

5. What monitoring and alarm functions does the product support?
The product offers a variety of monitoring and alarm functions, including real-time monitoring of voltage, current, temperature, and other parameters.
Users can remotely monitor the UPS's status through its control panel or network interface, keeping informed about the device's operation.
When the UPS detects abnormal conditions, it alerts users through audible and visual alarms or network notifications, assisting in timely action.

6. How to maintain the UPS's battery?
The battery is a critical component of the UPS and requires regular maintenance to ensure it functions properly in emergencies.
Users should regularly check the battery's voltage and capacity to ensure they are within normal limits.
The battery replacement cycle is typically 3-5 years, but the actual replacement time should be determined based on the battery's condition and usage environment.

7. What is the output voltage precision of the product?
The output voltage precision of the product is within ±1.0%, meaning it can provide stable and precise voltage output even under power grid fluctuations or load changes.
This high-precision voltage control effectively protects connected equipment from the impact of voltage fluctuations, extending their service life.
Users should ensure the load is within the UPS's rated range to achieve the best voltage stability.

8. How do the power supply systems achieve redundancy configuration?
To enhance system reliability, the product supports N+1 redundancy configuration, where additional UPS units are configured as backups.
In a redundancy configuration, if the main UPS fails, the backup UPS can immediately take over the load, ensuring uninterrupted system operation.
Users should consider redundancy configuration when designing systems to improve overall reliability and fault tolerance.

9. How to ensure the power supply systems operate normally under extreme temperatures?
The product can operate in environments ranging from -10°C to +40°C, but to ensure its performance and lifespan under extreme temperatures, certain measures are necessary.
Users should ensure the UPS's installation environment is well-ventilated and avoid high-temperature and high-humidity environments.
Regularly inspect the UPS's cooling system, clean dust and debris, to maintain good heat dissipation.

10. What is the maintenance cycle for the power supply systems?
The maintenance cycle for the product is typically every six months or annually, but the specific maintenance cycle should be determined based on the actual usage environment and load conditions.
Users should develop a maintenance plan based on the manufacturer's recommendations and the device's actual operation.
Regular maintenance can detect and resolve potential issues early, preventing service disruptions due to equipment failures.
