Network Rack PDUs Features & Benefits

Power Distribution & Load Management

PDUs power multiple devices in a server rack. Features such as alternating receptacles and locking receptacles help balance power and prevent accidental power cord disconnection. Their compact design allows for installation in confined spaces, making them easy to install. Some PDUs use fault-tolerant daisy-chain connections, meaning devices remain connected even if one link fails. IP aggregation allows multiple PDUs to use the same address, saving costs and simplifying management.

Monitoring & Remote Control

Modern PDUs (Power Distribution Units) can be remotely monitored and controlled. Sensors detect temperature and humidity to ensure safe operation. Staff can view power consumption and set alarms anytime, anywhere. Out-of-band communication serves as a backup in case of primary network failure. Data center teams utilize these tools to identify and quickly resolve issues early.

Safety & Protection

Every PDU must be safe and reliable. Manufacturers adhere to standards such as ISO 9001, UL, RoHS, and CE. These certifications demonstrate the PDU’s reliable quality and safe operation. PDUs undergo strength testing, plug-in life testing, and high and low temperature resistance testing. These measures are designed to ensure the safety of equipment and personnel.

Customization & Quality Assurance

YOSUN allows customers to choose the plug type, color, and module for their PDUs. The company verifies quality through special tests such as load aging and cable bending. Each PDU is inspected before shipment. After-sales support assists customers with setup and answers technical questions. YOSUN builds trust by helping customers over the long term.

Tip: Choose PDUs with good monitoring and security features to ensure stable operation of your data center.

Choosing a Network Rack PDUs

Assessing Power Needs

Choosing the right rack-mounted PDU starts with understanding how much power your equipment requires. Typically, businesses will list all their equipment. They will look at the power rating on each device label. Then, they will estimate the actual power consumption of the equipment. They will also consider the performance of the power supply. Redundancy is crucial for ensuring system continuity in the event of a failure. The team utilizes Power Usage Effectiveness (PUE) to plan energy-saving solutions. Allowing extra space for new equipment helps rack-mount PDUs meet future needs.

System planners ask several important questions before selecting PDUs: – What role will the rack-mount PDU play in the system? – How do we ensure continuous system operation and backup? – What types of alerts do we need to receive immediately? – What is the rack’s maximum power consumption? – What is our current voltage? – Which outlets are suitable for the equipment in the rack?

YOSUN helps users determine the optimal power configuration. Their team considers the rack placement, the equipment to be used, and any future additions. This ensures the rack-mount PDU perfectly fits the installation location and meets the needs of all equipment.

Tip: Always plan for more power than currently required. This helps prevent overload and allows you to add more equipment in the future.

Rack Configuration & Mounting

The way the rack is installed affects how the rack-mount power distribution unit (PDU) is installed and used. Vertical PDUs are mounted at the back or side of the rack, saving space. Horizontal PDUs, while capable of being installed within a rack unit, may take up some of your required space. The optimal choice depends on the rack shape and the number of devices you have.

The team will check the voltage, set the power budget, and select the appropriate circuitry, phase, and current. They will examine the equipment in the rack and decide if switching or special monitoring is needed. YOSUN allows you to choose the PDU mounting method and the required socket type. This makes rack PDU installation safer and easier.

Advanced Features

The new rack PDUs offer several features that enhance safety and usability. Multi-socket compatibility means you can use different types of sockets within a single PDU. High power support provides higher power per PDU, reducing the number of PDUs required. Power cord locking prevents accidental power cord detachment. Color-coded sockets help staff identify circuits and balance loads.

Monitoring is critical for data center management. Environmental monitoring displays temperature and humidity in real time. Remote switching allows teams to turn outlets on or off from any location. Real-time alarms alert administrators in case of problems, preventing equipment damage.

PDUs with switches can work with sensors to monitor the environment and adjust power as needed. This prevents equipment overheating and ensures equipment safety. YOSUN’s intelligent rack-mount PDUs offer the following features to ensure stable and safe system operation.
