The end Power Feed Box connects a power source to distributed power throughout the Busbar system. It can monitor the power data including voltage, current, frequency, apparent power, active power, reactive power, power factor, power consumption, load percentage, breaker On/Off state, temperature and etc. The voltage, current, power consumption and temperature of the main circuits can be displayed on the LCD screen as well. The power feed box can support either Ethernet or Serial communication. Through SNMP or Modbus-RTU protocol, the monitored power parameters and alarm notifications can be uploaded to the Main Control Box or DCIM platform in data center.
