High Quality Ip Pdu – JSY-MK-352 Metering intelligent PDU meter – JIAN SI YAN

• 2.1  Product Overview
• Single-phase and three-phase smart PDU meters are based on the innovative SUM (sustainable, scalable and maintainable) design concept technology. As a key component of the metering cabinet power distribution unit (PDU), after being installed into the main body of the PDU, it can Provides active metering capabilities for energy optimization and circuit protection. User-set alarm thresholds can effectively reduce risks by warning of potential circuit overloads through real-time local and remote alarms. Metered rack PDUs provide power usage data to support data center managers in making informed decisions about load balancing and proper IT sizing, thereby significantly reducing total cost of ownership. Users can configure metered cabinet PDU via Ethernet access or RS485. This series of products can be widely used in data center rooms such as IDC, banks, securities, governments, and enterprises.

2.3  Model selection

• ◆ MK-352IP stands for intelligent PDU meter head.

• ◆ JSY-MK-352AFE stands for three-phase four-wire power module.
• ◆ JSY-1073 stands for single-phase power module.
• ◆ JSY-1054 stands for 4-channel relay control module, current specification: 8A (maximum 16A).
• ◆ JSY-1084 indicates 4-channel relay control module, current specification: 20A ( maximum 50A ).

3. Main functions

3.1 Real-time monitoring function

• The display screen can view the monitored total load current, total voltage, total power, total electric energy, power factor, and load current parameters of each independent unit: the content displayed on the LCD screen can be viewed on the Web page, and the closed/open state of each independent unit, temperature/humidity sensor data and operating status can be controlled. 4-channel switch input can be configured by the customer, and there are 2-channel switch output.

3.2 Socket unit control

• ◆ Control the closing and opening of a single relay, or control multiple relays simultaneously.

• ◆ You can set the sequential delay power-on, up to 6 seconds. (This means that when two or more channels are controlled continuously, after the previous channel is completed, you need to wait 6 seconds before the next channel starts to operate.)
• ◆ Each relay can be set to start at a fixed time and date.

3.3 Customized alerts

• ◆ 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.

• ◆ The buzzer sounds. an email is sent to the system administrator. SNMP sends a trap alarm status information.

3.4 Master-slave (cascade) communication

• The two interfaces are the same RS485 communication bus, providing two interfaces for easy cascading. RS485 communication cascade can connect up to 4 instruments. Communication cables can use ordinary shielded twisted pair cables. When RS485 communication cables are routed outdoors, attention should be paid to the grounding of the cable shielding layer. The total length of the communication cable should not exceed 1200 meters. The positive and negative polarities of the RS-485 ports of each device must be connected correctly. If the shielded twisted pair cable is long, it is recommended to connect a 120 Ω resistor at the end and reduce the transmission rate to improve the reliability of communication.

5. Web Network Operation
5.1 Supported browsers

• You can access the PDU through its web interface using IE, Google 360, or Microsoft Edge . Other commonly used browsers may work but have not been fully tested.

5.2 Cascade Setting Instructions

• ◆ You can use the PDU's system IP address as the URL of the web interface and log in using a case-sensitive username and password.

• ◆ The PDU uses a static IP address by default when it leaves the factory. The default address is 192.168.1.190. The current IP address can be queried from the network status page on the LCD display of the display module. If you need to configure a dynamic IP, you need to enable the DHCP function of the device.
• ◆ Before using the cascading function, you need to select the master-slave mode for each PDU configuration. The master mode has only one PDU, and the slave mode can be configured with 4 PDUs by default .

5.2.1 Cascade settings

• After the PDU is powered on, plug the network cable into its network port. At this time, in the LCD display of the display module, by short pressing the button, you can query the IP address from the host information, as shown in the figure 192.168. 1 .1 90.
