Functions and Features
Function
Description
Input protection
Input overvoltage protection
In this protection state, the power module is turned off and stops supplying power. When the system recovers from input overvoltage, the power module can automatically start supplying power again.
Input undervoltage protection
In this protection state, the power module is turned off and stops supplying power. When the system recovers from input undervoltage, the power module can automatically start supplying power again.
Input overcurrent protection
In this protection state, the power module is turned off and stops supplying power. The power module cannot automatically start supplying power again and needs to be replaced.
Output protection
Output overvoltage protection
In this protection state:
If output overvoltage is caused by the power module itself, the power module stops supplying power. When the system recovers from output overvoltage, the power module cannot automatically start supplying power again.
If output overvoltage is caused by increase of the input voltage received from the external power source, the power module stops supplying power. When the system recovers from output overvoltage, the power module can automatically start supplying power again.
Output overcurrent protection
In this protection state, the output current is limited to a certain value. When the system recovers from output overcurrent, the power module can automatically start supplying power again.
Output short-circuit protection
In this protection state, the power module supplies power intermittently, and the output current is limited to a range. When the system recovers from output short-circuit, the power module can automatically start supplying power again.
Overtemperature protection
When the temperature of the power module exceeds a specified threshold, the power module stops supplying power. When the temperature falls into the normal range, the power module automatically resumes power supply.
Hot swapping
The power module is hot swappable.

PAC3KS54-NE FAQ
Q1: Can this UPS simultaneously power 8 servers (300W/unit) and 5 switches (100W/unit)? Is the power sufficient?
A1: Absolutely sufficient! The total active power is approximately 2900W, close to the 2.7kW rated value, with a 10% redundancy reserve, ensuring stable operation. For longer battery life, it is recommended to use it with an external battery pack.
Q2: What are the core differences between "double-conversion online" and "standby" UPS systems? Why is the former more suitable for critical equipment?
A2: The core difference lies in the conversion method and stability: Online UPS systems are powered by UPS voltage regulation and filtering throughout the entire process, with 0ms conversion; standby UPS systems only start when the mains power is abnormal, resulting in a conversion delay. Critical equipment has high requirements for power continuity, and online UPS systems can avoid equipment downtime caused by delays.
Q3: How is the backup time calculated after connecting an external battery pack? What is the maximum extension period?
A3: Backup time is inversely proportional to load power. At full load of 2.7kW, connecting one external battery can extend the battery life to 2 hours. Up to 4 batteries can be connected in parallel, extending the battery life to 8 hours, which meets the data backup needs of most scenarios.
