What is the output voltage of a communication base station?
Assume the output voltage of a communication base station’s power system is 48V, with the LLVD threshold set to 40V. When the mains power fails and the battery starts supplying power, the power system continuously monitors the output voltage through the voltage detection circuit.
What is a Blvd threshold for a communication base station?
Assume the rated voltage of a communication base station’s battery is 48V, with the BLVD threshold set to 42V. When the mains power fails and the battery starts supplying power, the power system continuously monitors the battery voltage through the voltage detection circuit.
What is a base station power cabinet?
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.
What happens when a comparator outputs a low level?
When the comparator outputs a low level, the relay or solidstate switch opens, cutting off the load power supply; when the comparator outputs a high level, the relay or solidstate switch closes, restoring the load power supply. The alarm circuit typically consists of a buzzer or LED indicator.
