Huawei ETP4890 Power System for IP DSLAM MA5600

An AC-powered cabinet uses the ETP4890 power system to convert the AC power to the DC power for power distribution. The small and modular ETP4890 power system supports easy installation and maintenance and effective LCD interface management. The power system supports a maximum of 90 A output current.

The ETP4890 power system supports the following functions:
* Converts AC power to DC power and provides the DC power for communication devices.
* Communicates with the upper device using a COM or an RS485/RS232 serial port; sends control signals based on the values of monitored parameters or the control command sent by the upper device; detects power distribution parameters, power supply module parameters, and auxiliary digital parameters in real time.
* Connects to one to two groups of lead acid batteries and uses a monitoring module to manage the batteries; provides complete management for battery charging and discharging, ensuring efficient battery usage.
* Connects to a sensor transfer box using a DB50 port, detecting analog parameters and digital parameters, and outputting control signals.
* Uses a monitoring module to monitor all running parameters for the ETP4890 power system in real time; determines the working status; reports alarms in a timely manner.
* Clearly displays the monitoring and alarm information on the liquid crystal display (LCD) of the monitoring module; allows operations such as parameter setting on the LCD of the monitoring module.
