Phoenix Contact QUINT Power Supplies
The QUINT power supplies from Phoenix Contact offer power solutions for various types of industrial applications. They have top-of-the-line features and a solid build that can provide power to the most critical systems and can do so continuously in a harsh environment. These power supplies are efficient and reliable, which makes them an obvious choice for a lot of different industrial and automation applications.
QUINT power supplies have advanced diagnostics and monitoring capabilities as a standout feature. This function helps in keeping preventive tabs on the unit continuously and ensures that any potential problems are identified and addressed as early as possible. Another helpful feature is that the QUINT power supply supports the dynamic boost and static boost functions, allowing for higher start-up currents and performance levels without collapsing under a pressure peak.
Power supplies of this kind can handle the entire range of input voltages. Hence, they can comply with the various global power standards. Also, because of this very reason, they are compatible with the electricity in use in different environments across the world. For the kinds of devices they power, they supply a very stable output voltage. This means that, irrespective of the input voltage, the devices that power supplies like these are connected to can attain a very high level of performance.

How to Select and Size a Power Supply
A power supply alters power from one type to another and ensures that the voltage being delivered is the proper level, with the right characteristics, to enable equipment to function properly.
Power Rating
If a power supply is rated for 5 amps at 24 VDC, (where voltage times amperage equals total wattage) the power rating for that power supply is roughly 120 Watts. This rating is very important because if this number is exceeded, it can cause a failure of the power supply and potentially damage other hardware wired downstream or on the load side of the device. To avoid this failure is important that the power supply is sized correctly.
Sizing a Power Supply
To properly size a power supply, identify what devices will be reliant on the power supply and what their total power consumption will be. The sum of all power to be delivered needs to be less than the total power rating of the power supply. For example, if the devices combined for a total of 100 Watts, then a 5 AMP power supply, which is rated for up to 120 Watts, would be sufficient. However, if the sum of those devices' total power requirement is greater than that of the power supply rating, then a different power supply should be selected. It is important to allow for a buffer or safety factor. When sizing a power supply, never select a power supply that is rated for the same amount of power as the total power requirement of all of the devices. Oversizing the power supply will allow for changes and additions that may occur in the future.
