This blog pages underline some very useful information to educate users before they commit to invest in hardware for their IT applications.
In general, power supplies that meet the IEC 60950-1 safety standard are designed to operate at commercial and residential areas, where altitude can vary from slightly above sea level to as high as 2,000 meters. However, many power supply manufacturers provide units that are designed to operate at higher altitudes, up to 3,000 meters or…
All power supplies have a specified “Operating temperature range”. For example, a particular 500W switching power supply has an operating temperature range from “-20°C to +70°C”. However, the specification may also state “Output derating linearly above +50°C”. So what does this mean? Most power supply manufacturers provide output derating curve (see figure below) to make…
Most AC-DC and DC-DC power supplies have internal current protection circuits to protect the power device and the majority of Over Current Protection (OCP) circuits include an automatic recovery feature. Power supplies that have only one OCP circuit are called “single-rail” while the power supplies that have more than one OCP circuits are referred to…
In an ideal world all the energy input to a power supply would be converted to useable electrical output power. Unfortunately real life systems incur losses and like all other types of power supplies, open frame power supplies generate heat which has to be dissipated during system operation. Key components that contribute to such losses…
The open frame power supply is generally a switching power supply consisting of just a PCB board and no enclosure. Open frame power supplies are designed specifically to be used inside of end products with specialized designs that provide an enclosure. Typically, the whole system will share one enclosure. Typical areas of concern when installing…
Server cabinets and open server racks ultimately server the same purpose, but their differences do define some noteworthy advantages and disadvantages, which can make choosing between the two difficult. However, which best suits you will ultimately be up to the environment that you plan to put your cabinet or rack in as well as your…
What is a Power Factor? When a power supply draws current from the wall (grid), it’s not always doing so in the most efficient manner. Power supplies that don’t have any kind of PFC or Power Factor Correction are likely to draw current in short bursts due to the nature of the energy coming from…
If you’re looking to invest in new server equipment, chances are, you’re also looking for the right server racks to go with it, but with all of the options available and all of the factors to consider, it quickly becomes clear that choosing the right server cabinet or open rack is not the easiest thing…
There are many potential benefits that a 100% digitally controlled redundant power supply can offer, including improved efficiency, reliability, and flexibility, so it may seem strange that the majority of power supplies in the market today function using controllers that communicate based on many basic analog protocols. This however, is primarily due to the…
When it comes to protecting data, there are many different important measures of precaution that need to be considered and implemented, and ultimately, ensuring your server’s safety and reliability means avoiding downtime at all costs. One of the most common provisions used to accomplish this is the redundant power supply, and it‘s one of the…
Many people don’t even consider the benefits of having a decent server chassis and altogether disregard the expansion limitations they might reach down the long road. In fact there are two primary server problems that can be routed back to a server’s chassis – overheating and server expansion limitations. Consider these three major points when looking…
The total cost of ownership for PC networks for your start up business could be overwhelming and could very well make up a large portion of your Non-overhead costs. However, this doesn’t have to be the case as you seek alternatives. Such an alternative would be Investing in a PC network that is 80 Plus…
