What does metered PDU mean?

What does metered PDU mean?

A Metered PDU distributes network-grade power and meters load in amps to prevent overloads and help users optimize load levels. 3. A Monitored PDU distributes network-grade power and helps users prevent downtime due to overloads or other power events.

What is the PDU for switches?

A switched rack PDU is a power management unit that can be mounted on an industry-standard rack and has the capability to toggle power on and off for individual power outputs remotely. Putting it all together, a switched rack PDU combines the strengths of a rack PDU with those of a switched PDU.

Is a PDU a power strip?

At the rack level, the terms PDU and power strip may be used interchangeably. Each manufacturer has a specific product category name: PDU, power strip, Rack Distribution Unit (RDU), Cabinet Distribution Unit (CDU), etc. Within the CPI product line, power strips are lower voltage, with minimal features.

What is a basic PDU?

Basic PDUs: A basic PDU is typically a power strip that accurately distributes the correct voltage and current to multiple outlets within an IT environment. The basic PDU can be used to supply power to IT equipment within racks.

What is PDU electricity?

A power distribution unit (PDU) is a device for controlling electrical power in a data center. The most basic PDUs are large power strips without surge protection. They are designed to provide standard electrical outlets for data center equipment and have no monitoring or remote access capabilities.

How is PDU load calculated?

Now that we know the load ratings, let’s look at how to calculate the total power output.

1. For a single phase Rack PDU, Total Power = (Total Current) x (208V)
2. For a three phase Rack PDU, Total Power = (Total Three Phase Current) x (208V) x [sqrt(3)]

How do I choose the right PDU?

Selecting a PDU for a rack of this size depends on how many devices you plan on installing and the devices’ power requirements. If your rack will house densely packed 1U servers, make sure you choose a PDU with ample outlet receptacles, plus some open outlets for future growth.

Can I plug a surge protector into a PDU?

In general, UPS systems have surge suppression already and you can just use a PDU without surge suppression if you need additional outlets.

How does a PDU work?

A power distribution unit, or PDU, distributes continuous network power to multiple devices. A PDU doesn’t condition or generate power but relays AC power from a generator, an uninterruptible power supply (UPS), or utility power source to networking hardware, servers, telecom equipment, and other critical devices.

How many amps can a PDU handle?

Based on the power cord that is used, the PDU can supply from 24 amps to 63 amps.

What is the maximum power capacity of a meter?

During normal energy use, the power supplied by your meter (9.2 kVA on average) should suffice. In theory, this allows you to simultaneously supply devices with a maximum power of 9.2 kW or 9200 watts.

How much power can a PDU handle?

What is the difference between a UPS and a PDU?

PDUs merely distribute power. They do not generate it. UPSs are essentially backup batteries in the server rack. They provide backup power in the event of an outage and complete protection against power quality problems.

Can I plug a UPS into a PDU?

Each PDU input cord plugs into an independent UPS, utility or generator power source. The PDU distributes power to equipment with redundant power supplies, providing an independent power source for each power supply.

Is a PDU a power supply?

Power Distribution Unit PDUs are responsible for distributing reliable network power to your multiple devices. It can deliver AC or DC power from an uninterruptible power supply, a generator, or utility power to equipment. Commonly used in data centers, PDUs distribute electrical power to connected servers.

How is PDU power 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).

How much power does a PDU use?
