What is a PDU connection?
What is a PDU? A power distribution unit (PDU) distributes reliable network power to multiple devices. It does not generate or condition power, but delivers AC power from an uninterruptible power supply (UPS), a generator, or utility power source to servers, networking hardware, telecom equipment, and other devices.
What does PDU stand for in electrical?
power distribution unit
A power distribution unit is a device for controlling electrical power in a data center. The most basic PDU is a large power strip without surge protection. It is designed to provide standard electrical outlets for data center equipment and has no monitoring or remote access capabilities.
Can you plug a PDU into a PDU?
Connecting additional equipment to a PDU can overload the PDU or the supply circuit, causing equipment downtime. Metered, Monitored and Switched PDUs display load levels in real time, allowing additional equipment to be connected safely. When the UPS system is restored, the PDU will switch back to the primary input.
What is a 3 phase PDU?
3 Phase power is used in data centers to support high density IT applications and minimize the cost of the cables delivering that power. In the past, this meant carefully dividing power evenly across the three branches of the rack PDU so that you could draw roughly similar current on each branch.
What are PDU hours?
Professional Development Units (PDUs) are one-hour blocks of time that you spend learning, teaching others, or volunteering. PDUs are broken into two categories — Education and Giving Back to the Profession. Education PDUs can be earned at professional seminars, webinars, classes, or even self-directed learning.
Why do I need a PDU?
At its most basic level, a power distribution unit, or PDU, serves the same function as a power strip. It allows you to put electrical outlets where they are needed. Measure Electrical Usage – PDUs will typically measure how much electricity is being used by each outlet.
Is a PDU the same as a surge protector?
No, PDUs do not have surge protection.

How do you connect to PDU?
Connect an Original PDU to a Static IP Address Network
- Connect a crossover patch cable from the system to the PDU metering unit’s RJ-45 Ethernet port.
- Connect the PDU power input lead to the AC power source.
- On the system, use a web browser to log in to the PDU metering unit.
How is PDU load calculated?
On a 3 phase PDU outputting 120V the calculation would be Volts x Amps (80%) x 3 (# of independent conductors). For example, a 30A 3 phase unit outputting 120V would be 120 x 24 x 3=8.6kW. If the PDU is outputting 208V, the calculation would be Volts x Amps (80%) x SQRT(3).
