PDU Modules for Network Remote Monitoring and Management Power Distribution System

3 - The main function

3.1 Real-time monitoring function

The monitored total load current, total voltage, total power, total electric energy, power factor, and the load current of each independent unit can be viewed through the LCD display interface and buttons: the content displayed on the LCD screen and each independent unit can be viewed on the web page. The unit's closed/open status, temperature/humidity sensor data and operating status, 4 switching inputs can be configured by customers, and two switching outputs.

3.2 Outlet unit control functions

1、When a close (close) command is received, the relay closes.

2、When receiving the disconnection (opening) command, the relay opens.

3、To control the opening and closing of multi-channel relays, you can set the sequential power-on delay, up to 6 seconds. (This means that when two or more channels are controlled continuously, after the action of the previous channel ends, you need to wait 6 seconds before the next channel starts to act.)

4、Each relay can be turned on at a scheduled time and date.

3.3 Initial state settings

The state of each socket unit when it is powered on is the state when it is powered off, which is a maintained state.

Note: The function of the holding state is that the relay state after power-on is the state before power-off. the function of the off-state is that the relay is in the off-state after power-on. the function of the closed state is that the relay is in the closed state after power-on.

3.4 Custom alarm

The total load current/voltage over-limit threshold can be customized, the load current over-limit threshold of each socket unit can be customized, and the temperature/humidity over-limit threshold can be customized.

3.5 Various alarm methods

The buzzer sounds. the backlight of the LCD screen is always on. An E-mail is sent to the system administrator. SNMP sends Trap alarm status information.

3.6 Unit current overload monitoring

Detect the load current of each outlet output unit. If the load current of an output unit exceeds the threshold setting, the device buzzer will sound and the LCD screen will automatically light up. If an alarm notification mailbox is set, alarm information will be sent to the mailbox. The current value of the socket output unit flashes on the LCD screen and can be queried by pressing the button. If the load current exceeds the threshold setting, the buzzer will sound an alarm. You can click the up/down button on the panel to silence it, and the alarm will not be blocked.

3.7 Master-slave (cascade) settings

Set the master and slave status in the web interface. Only as the master can read the slave information. There cannot be duplicate addresses in the cascade network, otherwise communication abnormalities will occur.
