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 a PDU device?

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 is a PDU outlet?

A power distribution unit (PDU) is a device fitted with multiple outputs designed to distribute electric power, especially to racks of computers and networking equipment located within a data center. Basic PDUs simply provide a means of distributing power from the input to a plurality of outlets.

What is a PDU strip?

A PDU, or Power Distribution Unit, is a device used in data centers to control and distribute electric power. The most basic form of a PDU is a large power strip without surge protection.

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.

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.

Can you plug a PDU into a PDU?

Generally, the PDU goes into the UPS, not the other way around. That way, all the equipment that is connected to the PDU benefits from being backed up by the UPS. The UPS itself will clean the power. The PDU goes on the OUTPUT of the UPS.

Can I 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.

Can I plug a UPS into a PDU?

What is single-phase PDU?

According to Power Phases: Single-phase vs Three-phase PDU Single-phase power systems distribute up to 120V of alternating current. It is calculated as volts multiple amps and is described as volt-amps or VA. A 120V, 20A circuit has an apparent power of 2400VA or 2.4kVA.

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).

Is it safe to plug PDU into UPS?
