DIN rails are the long metal strips that structure the center piece of a worldwide industry standard equipment rail-mounting system. DIN rails have found its main use in attaching industrial as well as electrical control products securely, like terminal blocks, actuators, circuit breakers, solenoids, etc. inside a rack housing frame or cabinet.
In the above context, the word DIN stands for Deutsche Institut für Normung which is a German statement. When translated to English it says ‘German Institute of Standards’. The rack mounting system that we see today supporting several industrial settings was devised earlier in the late 1920s by the German. By 1950 it was completely developed and adopted, first by the neighboring countries in Europe and then across the globe.
Types
The DIN rail comes in 3 different types.
- Top Hat Section, Type Ω or Type O having cross-section that is in shape of a hat.
Top Hat Rail IEC/EN 60715
This rail is 35 mm wide and is used to mount relays, motor controllers, circuit breakers, programmable logic controllers, etc. It is also known as the TS35 DIN rail in the USA.
C Section rail AS 2756.1997 (C30)
The most popular used C section rails are C50, C40, C30, and C20. The number that is present in the suffix of 'C' specifies the net vertical height of the rail.
The G rail is utilized to hold high power and heavier components. It is mounted with the deeper side at the base, and hardware is snared over the lip, at that point pivoted until it clips into the shallower side.
DIN Rail Power Supply
This central unit for the distribution of power takes in AC line voltage and transforms it into DC voltage and is situated in an electrical cabinet placed on a DIN rail. DIN rail power supplies are most popularly utilized in electrical cabinets as well as control panels to support industry standard 48V, 24V or 12V DC. They should be guaranteed to UL60950 general purpose power supply and UL standard 508 performance and safety standards for automation in factories.
These days the market is seeing a huge drop in the prices of DIN rail modules and the reason behind this is due to intense competition and "economy of scale". Thus, they are gaining their popularity in security technology, smart home applications, and building automation.
Things to consider while choosing a DIN Rail Power Supply
If you require a perfect DIN rail power supply for your cabinet, you need to take care of a certain number of things to find the desired one.
- Input/Output – For supporting global compatibility, it is recommended to go for a wide AC input voltage range. It should accept a wide frequency range as well as cover most line voltage.
- Connection and Wiring – Wires connected to the power supply unit should have shorted cable length and largest cross-section possible.
- Low Maintenance Cost and Reliability – For professional use we recommend you to go with a costly one as you can't afford any failure but if it's required in a non-professional field where failure is not a big issue then you can opt for lower-cost equipment.
