Base Station Energy Monitoring Solution
Application
It is necessary to measure and monitor electrical parameters and measure energy in AC side of tower base station such as state grid, diesel, air conditioner, lighting, power supply and so on. In DC side, it is necessary to monitor electrical parameters and measure energy such as base station communication device, battery and other devices working under -48V power supply. The data can be real-time uploaded by RS485.
Structure
Acrel Base Station uses three devices to monitor the whole energy flow:
1. AC Multi-Channel energy meter is mainly used to monitor AC air-conditioning, lighting, other devices electrical usage
2. DC Multi-Channel energy meter is mainly used to monitor DC communication devices, and account for different Telecom operators' electrical usage.
3. Without energy consumption monitoring, Acrel also offers the Lead-Acid Battery's Life-Circuit Monitoring device, to make sure your UPS backup power working normally
