    Traditional PDU Limitations

    You have seen the role of the pdu change dramatically over the past decade. In the early days, you relied on basic units that only distributed power to your equipment. These traditional devices lacked the intelligence and flexibility you need for modern telecom cabinet power monitoring. You often faced crowded racks because these pdus occupied significant space, which restricted airflow and increased heat retention. The wiring complexity created a tangled network, making it difficult to manage temperature and airflow. Inefficient power distribution led to excessive energy consumption, overheating, and higher maintenance costs due to voltage fluctuations.

    You also encountered several operational challenges. Older rectifier modules in these pdus only achieved 85-90% efficiency, which resulted in unnecessary energy loss. Maintenance and upgrades became difficult because of the lack of standardization across equipment. Environmental factors such as dust, moisture, and temperature swings threatened the reliability of your sensitive electronics. These limitations made it clear that traditional pdus could not keep up with the demands of advanced telecom cabinet power monitoring.
