Functions of the PAC1K2S12-PB
Functions
Description
Input overvoltage protection and undervoltage protection
In this protection state, the power module stops supplying power. When the input voltage restores to the normal range, the power module automatically resumes power supply.
Input overcurrent protection
In this protection state, the power module stops supplying power and cannot automatically resume power supply when the input current restores to the normal range.
Output overvoltage protection
In this protection state, the power adapter stops supplying power intermittently. When the output voltage restores to the normal range, the power adapter automatically resumes power supply.
Output overcurrent protection
In this protection state, the power module supplies power intermittently. When the output current is limited within a range, the power module automatically resumes power supply.
Output short-circuit protection
In this protection state, the power module supplies power intermittently. When the short circuit is removed, the power module automatically resumes power supply.
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.
Heat dissipation
Back-to-front airflow
Hot swapping
The power module is hot swappable.

PAC1K2S12-PB FAQ
Q1: Which Huawei switch models is the PAC1K2S12-PB specifically compatible with? How is its compatibility?
A1: It is primarily compatible with the entire Huawei CE16800 series and XH series switches, and is compatible with all Huawei network devices that support this power supply specification. Compatibility is 100%, and an official compatibility list is available for reference.
Q2: What are the conversion efficiency and energy-saving effects of the power module? How much cost can be saved in the long term?
A2: With a conversion efficiency of ≥94%, it can save approximately 300 kWh of electricity per unit per year compared to a typical 80% efficiency power supply (based on 24 hours of operation per day). The energy-saving effect is significant in large-scale deployments.
Q3: Does it support hot-swapping and redundant deployment? Will maintenance affect services?
A3: It supports hot-swapping design, allowing for replacement without downtime; it supports multi-module redundant deployment, ensuring that a single module failure does not affect power supply or service operation, resulting in zero maintenance risk.
