Power frequency 3-U 10-30KVA

Chengwen 3-U 10-30KVA independently developed, using industrial grade CPU, powerful computing and processing capabilities, and the most popular SMT surface mounting process in the electronics industry. High reliability, strong anti vibration ability, and low defect rate of solder joints. Reduced electromagnetic and radio frequency interference. The product is widely used in servers, storage devices, network equipment, VIOP communication equipment, automation equipment, precision instrument equipment, transportation operations, power equipment, marine ship UPS, etc.

1. Superb adaptability to the power grid

The wide input voltage range of 380V ± 25% enables UPS to operate normally in various harsh power grid environments, reducing battery discharge opportunities and extending battery life.

2. Cold start function

In the absence of mains power, the UPS can be directly started with the battery pack to meet the emergency needs of users.

3. Super strong load compatibility

Strong load-bearing capacity, good load compatibility, can be applied to various types of loads, and meet the needs of various application scenarios.

4. Comprehensive protection functions

It has multiple protection functions such as input overvoltage, undervoltage, output overvoltage, undervoltage, output overcurrent, short circuit, battery undervoltage, battery overcharge, power device overheating, etc., ensuring the reliability of system operation.

5. Zero switching time

Built in static electronic bypass switch, when UPS is protected or fails due to various reasons, it can switch to bypass power supply without interruption, especially suitable for equipment with strict requirements for power outage time.

6. Improved battery management technology

Provide the most reasonable charging current according to the battery parameter curve, set the optimal charging current based on the battery capacity, and adopt advanced equalization floating current automatic conversion technology to improve battery efficiency and extend battery life.

7. High current charger

Built in high current charger, suitable for frequent and prolonged power outages.

8. Large screen LCD+LED display, seamless human-machine communication

The working status of UPS can be determined through LED, and the input and output battery parameters of UPS can be viewed through LCD. Enable users to stay informed about the working status of UPS at any time.

9. Intelligent monitoring function

Through the RS232 interface, combined with UPS intelligent monitoring software, it can communicate with a computer, and various operating parameters of UPS are displayed at a glance on the communication interface. By installing SNMP cards, UPS can also achieve network monitoring function, allowing remote observation and management of various operating parameters of UPS through the network.

10. Can achieve series hot backup or parallel redundancy
