If one of the voltages is less than 10 V, check whether a phase of the power input has failed.Check that the switch closes normally and no tripping alarm is generated. Restart the centralized monitoring board. If the fault persists, replace the board..

The base station power cabinet is a key equipment ensuring continuous power supply to base station devices, with LLVD (Load Low Voltage Disconnect) and BLVD (Battery Low Voltage Disconnect) being two important protection mechanisms in the power cabinet. This article will provide a detailed analysis. .
When found in an individual control module, it's most likely a local source (e.g. wiring/connectors). When found in multiple control modules at the same time, it's most likely a common source (e.g. ground spot, battery, generator). Intermittent codes are often stored during low outside temperature. .
LLVD (Low Voltage Disconnect): Definition: LLVD refers to a safety feature in power systems that disconnects or cuts off power when the voltage falls below a certain threshold, preventing further damage to equipment or batteries. Function: This mechanism is generally used in DC power systems to. .
The voltage of the power supply grid is unstable: the grid voltage fluctuates greatly and is lower than the operating voltage required by the equipment. The power supply line is too long or the wire quality is poor: The wire is too long or the wire quality is poor, which will cause a large voltage. .
A “voltage irregularity” occurs any time that your voltage supply deviates from the nominal voltage required by your electrical system. This deviation can take the form of power surges, voltage drops, or other random voltage changes. While a slight power fluctuation may not even be noticeable. .
After rectification, AC power can be obtained as DC power. However, due to the changes in AC voltage and load current, the DC voltage obtained after rectification usually causes a voltage change of 20% to 40%. In order to obtain a stable DC voltage, a voltage stabilization circuit must be used to.
