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-CB FAQ
Q1: Can this UPS simultaneously power 2 mini servers (300W/unit), 1 router (50W), and 2 office computers (100W/unit)? Is the power sufficient?
A1: Absolutely sufficient! The total active power is approximately 950W, far below the 2.7kW rated value, with ample redundancy for stable operation. The standard battery can meet data backup needs after a power outage.
Q2: What are the core differences between this UPS and the Huawei PAC3KS54-CE? How should small and micro-enterprises choose?
A2: The core differences lie in functionality and battery life: The PAC3KS54-CB (compact, basic functions, supports 4 hours of battery life) is suitable for small and micro-enterprises with limited space and simple needs; the CE model (supports remote monitoring, 6 hours of battery life) is suitable for scenarios with remote management needs. For basic uninterrupted power supply, the CB model is more cost-effective.
Q3: Without professional maintenance personnel, is installation and daily maintenance difficult?
A3: Extremely easy to install! Tool-free tower installation; simply unpack and connect to AC power and the device. The unit has a fault indicator light for easy monitoring of its operating status. No additional maintenance is required; simply replace the battery when it degrades.
