Computer Power Distribution Units
Supplying computer power to multiple machines is a delicate matter that involves some planning. Computer power distribution units or PDUs are designed to organise your power supply and bring a stable flow of electricity to each node. Using a simple 240V power distribution unit ensures that each and every computer connected to it will get 240V of electricity. There are different kinds of PDUs and different features on them, so choosing between them requires a better look at their specs.
Voltage CompatibilityA big part of choosing the right computer power distribution unit is selecting the right voltage. If you need a 220V power distribution unit, you should not opt for a 230V power distribution unit as those 10V make a lot of difference. The computer itself usually has a 10 to 20V tolerance, but the PDU might not work properly if you do not match it with the power coming out of your outlet.
Max PowerPower is an expression of both volts and amperes, so once you know your voltage, you should focus on the amperes expressed in the specs. The more amperes a PDU can support, the more machines you can connect to it. Of course, not all computers are equally powerful, so you should work out the maximum demand of your computer units as well as the maximum amperes you can get from the outlet in the wall. There may also be a maximal output limit on a single outlet on the PDU itself.
Type and Number of OutletsComputer power distribution units can come with several types of outlets depending on their primary use. Some are designed to serve whole computers, while other are focused on supplying server equipment. You can even find models with combined outlet types such as C13S and C19 outlets on the same unit.
