The Right Power Supplies Make All The Difference

In general a power supply is a way to convert a standard electrical source into a specific output voltage so it is compatible to run a variety of different types of equipment. This can include higher or lower voltage requirements and can also run on DC or AC output depending on your needs. These small, lightweight and portable or permanently mounted power supplies are ideal for any specialized work area or even for use with specialty types of equipment.

Some of the most common types of uses for these supplies are in industry specific types of sensors and other equipment that require a consistent, steady power supply to operate correctly. These include input solenoids, sensors, programmable logic controllers, relays, valves and switches. These supplies should be certified to meet specific standards based on their intended use. The most common criteria include UL and C-UL listed as well as CSA and CE certified, which ensures that the power supplies are safe for intended use. They also have a rating based on the class and division of hazardous products they are approved to use with, if this applies to the particular supply.

Power supplies can be designed to help handle high inrush types of loads. This is done by having a boost capacity within the supply, ensuring that the system won't shutdown or foldback, providing a constant output level. Many of the supplies offer an auto select or variable input control, which means they can be used under a variety of conditions. Generally these smaller supplies are DIN mount capable, ideal for locating on DIN rails in tight spaces.

AC to DC converters are also ideal for different types of applications. These small, lightweight and highly portable units can have an output voltage of 13.8 VDC and an output current of 5 Amps. The input voltage can be 120/60 volts, providing lots of usage options. This system will protect against overcurrent, preventing damage to equipment running on DC when plugged into AC. In addition the unit smoothes out the spikes or constant noise found in the AC power as there are drains or surges in the line, eliminating this in the level and flat output to the DC side.

There are many different options when it comes to power supplies. Simple and efficient supplies are critical to the operation of sensitive types of equipment, so it is important to know exactly what you want out of the supply before making a decision. There are supplies available that have all types of diagnostics and recording of power fluctuations and system power usage built in. This may be an important consideration in highly sensitive areas such as laboratories, computer systems and in electrical equipment and sensors. Many have LED displays that allow the operator to quickly check that the supply is functioning correctly, helping in critical diagnostic checks or in getting essential equipment back up and running as quickly as possible.

In some areas the temperature range for power supplies will also be an important consideration when choosing a model and style. Some are able to operate in a wide range of temperatures while others are much more heat sensitive. Typically the supplies approved for use in hazardous areas are much more tolerant of higher temperatures however there are several different options to choose from. In addition to temperature the actual casing on the supply can be metal or plastic, which also impacts the temperature range as well as the weight, standards and durability of the supply.
