1. Product Description

The fully intelligent PDU developed and produced by Kotohira provides rich interfaces and management functions. Users can choose  corresponding products according to actual needs. It is very suitable for medium and large data centers, integrated computer rooms and other industries.

2. Features

1) High performance index 

◆ Double-precision high-performance computing provide accurate electric energy measurement and PF data for  single socket.

◆ Color LCD display

It adopts a color LCD display to visually display voltage, current, power factor, electric energy, IP address, temperature and humidity, CAN/485 hardware address and other information.

◆ Provide real-time power monitoring

Using efficient data processing methods, it can not only provide real-time data such as input current, voltage, power, power factor, electric energy, frequency, etc., the PDU with each socket detection function can also provide the power output of each socket, which can be displayed in real time Current, power factor and energy per outlet. Provides the function of curve image display.

◆ Ability to turn on/off a single outlet remotely

The PDU with each socket control function can realize remote control function through HTTP, SNMP, SSH and other network protocols. Various protocols can provide encrypted SSL to make remote control more secure and reliable.

◆ Socket metering function provided by PDU

It can provide users with the basis for accurate calculation of PUE to inform data center managers with a basis for reducing costs for load balancing and setting up the IT environment.

◆ User-definable alarm thresholds reduce risk through real-time local and remote alarms to warn of potential circuit overloads.

◆ Advanced switch function, which can realize user-defined logic control, can independently realize the switch action and schedule of each socket position, and can take intelligent actions according to environmental changes.

The user can control the PDU output switch according to the current threshold and temperature threshold, and give a variety of alarm prompts at the same time. There is a parameter copy function between the sockets. After setting the parameters of one socket, it can be quickly copied to other sockets. At the same time, for socket management PDU, Each socket can switch sockets according to the time or time period set by the user. It has 20 user-defined time or time period editing functions to meet the complex logic control needs of users.

◆ Socket sorting delay to avoid circuit overload, When switching sockets or powering on, the power-on time interval can be flexibly set between sockets, it conducive to the stable operation of the load and avoids surges.

◆ Socket group management function

PDU with single socket management, users can customize socket grouping, flexible grouping of sockets is helpful for users to manage sockets. Also the hardware is independently divided into 3 groups, each group 8 sockets. The three-phase PDU also achieves electrical isolation for each 8 sockets.

◆ Users can access and configure various access control methods through the secure Web, SNMP, SSH or Telnet interface.

◆ Provide isolated 2-way temperature/humidity sensor, 3-way input and 1-way output port

◆ Provide isolated CANBUS, RS485 serial networking mode

The PDU not only provides common SNMP management functions, but also collects data and controls equipment through serial ports such as CANBUS and RS485. In small and medium-sized data centers or environments without network conditions, the PDU provides multiple integration methods to facilitate secondary development for users.

◆ Compatible with Jeidar SNMP Link network management system.

SNMP Link provides power equipment management and environmental monitoring for small and medium data centers. SNMP Link can manage devices such as power distribution cabinets, PDU, ATS, STS, UPS, and air conditioners.

2) Rich Network Service Functions

◆ Provide HTTPS management, support TLS encryption authentication, TLS1.0 and above standard.

◆ Provide SNMP V3 Agent, support DES or AES authentication. Provide MD5 or SHA private encryption and provide SNMP function, which can facilitate secondary development and facilitate the integration of other data center management software with SNMP network management functions. At the same time, SNMPV3 also provides encryption protection.

◆ Support Telnet and SSH

Support network commands to view and operate devices, and SSH provides network security encryption.

◆Support network firewall

Provide network protection such as data packet filtering and anti-PING.

◆ Provide NTP time synchronization

Network clock synchronization, this function can provide accurate device time when the device is connected to the Internet.

◆ Provide operation, event log and battery time record

The event log mainly records equipment operations and alarms, operation log provides equipment data records, including equipment input and socket output information, power records.

◆ Provide PDU configuration download and upload function

This function is mainly used for quick configuration of batch PDUs. The user can set the parameters of a PDU, then download the parameters of the PDU, and upload the parameters to other PDUs of the same type to realize the rapid configuration of the device. At the same time, setting parameters can also be downloaded and backed up. Once reset is required, quick configuration saves time.

3) Safe and Stable

◆ Network security

Support TLS encrypted authentication. support SNMPV3 encrypted communication. Encryption method can be selected. support SSH command line. support SSL mail sending, support network firewall.

◆ Electrical safety

All external sensor interfaces and communication interfaces are isolated.

◆ Memorable status recovery

When an abnormality occurs and the device is restored, able to maintain the original state of the memory and restore quickly.

◆ Latest Linux kernel version 4.0+ and encryption library. Repair most of the system security holes.

◆ Provide online software upgrades to meet special application scenarios and reduce maintenance costs.
