Maintenance precautions
(1) Daily inspection
Regularly check the working status indicator light of the power supply. Under normal circumstances, the indicator light should light up or flash according to established rules. If there is abnormal flashing, extinguishing, or abnormal color on, the power supply working status should be checked immediately to determine if there is a fault.
Use professional instruments to detect the output voltage and current of the power supply every month, ensuring that they fluctuate within the rated range. If there is a significant deviation in output voltage or current, it is necessary to calibrate or repair it in a timely manner.
(2) Cleaning and maintenance
Regularly clean the dust on the surface of the power supply, at least once every quarter. Use a dry, soft brush or vacuum cleaner to remove dust from the power supply casing, avoid wiping with a damp cloth, and prevent moisture from entering the interior of the power supply.
For long-term use of power supplies, it is necessary to open the casing every year (under the condition of power outage and ensuring safety), clean the internal dust, and check whether the internal components are loose, deformed, burnt, and other phenomena. If any abnormalities are found, promptly contact professional maintenance personnel for handling.
