PDU classification
01
Ordinary PDU, with all aluminum alloy structure, has better flame retardant performance than plastic body, advanced spraying process has long corrosion resistance life and shielding more electromagnetic interference.
02
High voltage DC PDU has many advantages. Firstly, DC power supply only has one parameter of voltage amplitude. There is no problem of phase, phase sequence and frequency synchronization between DC modules. The system structure is simple and reliability is greatly improved; Secondly, compared with AC UPS system, DC power supply saves the inverter link, and the loss of the inverter is about 5%, so the efficiency of the power supply is improved; Thirdly, because the server input is DC, there is no power factor and harmonic problem, which reduces the line loss.
03
The lightning protection PDU, the lightning protection in the PDU of cabinet socket is not direct lightning protection, but the surge between electrical appliances. It is a third level lightning protection against lightning, which is anti lightning induced high current. Add lightning protection module to avoid transient surge, protect the power equipment in the machine room, enhance the impact current resistance and improve the protection of the equipment.
04
ATS PDU and dual power switching PDU can provide redundant power for connected equipment during the use. When one power supply fails, it will automatically switch to another power supply for power supply, which can improve the reliability and availability of power consumption at the end of the machine room.
05
Intelligent PDU, also called remote power manager, can monitor, control, display and manage electrical parameters through Ethernet interface or RS232 interface. The monitoring object includes the total current, port output current, voltage, power factor and port switch status of PDU; Control refers to the ability to remotely switch the PDU output port. In addition, intelligent PDU can realize more enhanced power security of IT equipment through intelligent protection measures, so it has a significant improvement in security than ordinary PDU.

Remote control:

The power switch of any output socket is controlled remotely through the communication protocol between web page and SNMP.

Current measurement:

Measure the total output current.

Event notification:

When the socket switch and power are overloaded, email and SNMP trips are sent to the intended manager account.

Warning settings:

Set the current warning value, and if the power consumption exceeds the warning value, an event notification will be sent.

Overload protection:

The power consumption is overloaded, and the breaker will trip d to avoid danger and protect the safety of power consumption.

Centralized management:

Free centralized monitoring software, real-time monitoring a large number of interpolation, provide power records and power curve.
