01.
One-Click Status Prediction
No action is required—simply with a single click, you can receive early warnings about the status of critical parameters for key components in your equipment.
02.
Fully redundant design
No action is required—just one click to predict the lifespan of power supply equipment and its critical components.
03.
One-touch power on/off
No manual intervention is required—simply press a single button to initiate power on/off according to the pre‑configured sequence and critical system parameters, ensuring successful startup and shutdown. During these operations, the system autonomously monitors key parameters, preventing failures caused by incorrect settings and safeguarding against potential equipment malfunctions or accidents.
———— Key parameter monitoring of the power supply unit itself ————
Warning parameters: internal temperature, input voltage and current, DC voltage and current, output voltage and current, and ground insulation.
Fault‑diagnosis parameters: failure of critical components, internal temperature, and ground insulation.
