Description
The 1U base station DC load intelligent management unit is an intelligent switch device that is carefully designed and manufactured based on the power consumption of the tower base station, combining advanced power metering dedicated chips with mature power management technology. Each household has a built-in DC contactor to manage the power distribution (backup power) of each household according to user needs. It has RS485, NB-IoT or 4G communication functions to realize data exchange between the slave and the host (computer\FSU). It is suitable for DC equipment power management, power measurement, power metering, etc.

Functions
1.Control Function
- Timing on-off control
- Backup power duration control
- Backup voltage control
- Backup power control
- On and off during the exemption period
2. Metering function
This equipment has the functions of household (channel) measurement and statistics: it has the functions of measuring the voltage, current, power and electric energy of the whole measurement equipment and each household (channel), and has the power and electric quantity of the whole equipment and each household (channel). Features.
3. Detection function
This device supports the detection of the power supply status (yes, no) of the mains outside the base station, and sets the trigger conditions according to other requirements of the user to control the on-off status of the device’s DC output.
4. Power-off memory function
This device has a power-off memory function. After power-off, all the set parameters and judgment logic remain unchanged, and it can enter the working state according to the specific conditions after the power-up. When the equipment fails, the contactor is automatically closed, which does not affect the normal operation of the base station system
5. Communication function
The device has RS485 communication connection port and supports NB-IoT wireless remote communication function.
6. Overcurrent and short circuit protection
7. Data monitoring function
