A Comprehensive Guide to UPS Uninterruptible Power Supply ( Part 4)

(5) Main Control Intelligent Control System: The “brain center” of the UPS power supply, equipped with a high-precision power detection chip and intelligent algorithm program, can monitor real-time mains voltage, current, frequency, battery power, equipment temperature, load rate, operating status and other full-dimensional data. It automatically switches the working mode according to the power status, and has multiple intelligent protection functions such as overload protection, short circuit protection, over-temperature protection, over-voltage and under-voltage protection, and battery overcharge and over-discharge protection. The high-end UPS control system supports intelligent functions such as remote monitoring, data upload, intelligent alarm, scheduled operation and maintenance, and parallel linkage, and is suitable for the needs of modern intelligent computer rooms and industrial operation and maintenance.

(6) Filtering Module: Mainly divided into input filtering and output filtering, its core function is to filter out harmonic interference, high-frequency noise, surge current , and voltage spikes in the mains power supply, optimize the power supply waveform, and purify the power supply environment. During the transmission process, the mains power supply will generate a large amount of noise due to line aging, interference from surrounding equipment, and fluctuations in grid load. This kind of inferior power will accelerate the aging of precision equipment and cause data transmission errors. The filtering module can completely solve such problems and provide clean power for precision loads such as back-end servers, switches, medical equipment, and industrial controllers.

(7) Protection module: It integrates multiple protection mechanisms such as overvoltage, undervoltage, overload, short circuit, overtemperature, battery abnormality, and lightning strike protection. It can quickly activate the protection mechanism when there is power abnormality, equipment failure, or environmental abnormality, cut off abnormal power supply, lock the fault status, avoid safety problems such as equipment burnout, load damage, and circuit short circuit, and comprehensively protect the operation safety of UPS equipment and back-end load equipment.

(8) Heat dissipation module: Includes intelligent cooling fan, heat dissipation duct, heat dissipation base plate and other structures. UPS power supplies generate a certain amount of heat during power conversion and load operation, especially high-power modular and industrial frequency UPS equipment, which generate a lot of heat. The intelligent heat dissipation module can automatically adjust the heat dissipation power according to the equipment operating temperature, ensuring that the equipment operates stably within the rated temperature range, avoiding equipment derating, failure and lifespan reduction caused by high temperature, and adapting to the working conditions of long-term uninterrupted operation.
