Server how many amps

One kilowatt is equal to 1, watts. You can convert watts to kilowatts by dividing 1, You can find the kilowatts by simply dividing by 1, What is a Kilowatt Hour? A Kilowatt Hour , abbreviated kWh , is a measure of the number of kilowatts your electrical device uses over a certain time period.

How many kW are your electrical devices consuming if they are powered on for an hour, two hours or 24 hours a day? Kilowatt Hours kWh are used by utility companies to charge their customers for the power that they consume. For example, you have a server that requires W and it runs 24 hours. In a one day period, your server would consume 9,W or 9. What is Kilovolt Amp? A Kilovolt Amp , abbreviated as kVA , is a measure of the apparent power in an electrical circuit.

What is single phase power? Single phase power supplies power through a single conductor. The max voltage for single phase is V. What is three phase power? Three phase power flows through three conductors and has three distinct wave cycles. Three phase power has three or four wires. The first step is to calculate the total maximum power draw in kWatts, then from the mentioned formula, you can find out how many Amps your system will draw.

Let say you need a 10U space with the following specification:. Though the formula shows you need 18 amp for this set up in your rack, but this is for maximum use and not all the time your servers and routers are on max use. The reason that we use only one of the 9-amp values is due to how primary and redundant power are configured.

Primary and redundant power means two or more power supplies from different sources of power. Because the PDUs have the same gear connected to each, they should draw the same amount of power. When planning for power redundancy, each circuit primary and redundant must be sized to handle the total load of both in case one fails.

First, we look up the manufacturer power specifications online to find:. This is in case you would like to adjust the calculation based on the production load. When planning, you would consider your equipment to be running at Plate Rating as the worst-case scenario since it would be at full capacity. Whether you want to use this tool is entirely up to you. If you do not wish to use this feature, just leave it at It is now your job to see if this facility is a good deal.

You can use the server rack power consumption calculator above to follow along. The first thing you need to do is calculate your Watts Per Square Foot ft 2. Next, you will then divide 1,, W by your usable square footage of 13, ft 2 which equals Watts per ft 2. Next, you need to calculate the Number of Racks that can fit in this space.

On an 8-pitch layout, one rack requires 16 ft 2.
