New compact power supplies for industrial use, especially Automation and Panel Building
What are DIN rail power supplies?
In the world of electronics it is very common, especially in the industrial field, to hear about DIN Rail or DIN Rail-mounted devices – a family that also includes DIN rail power supplies, the subject of this article.
Why are these devices, including power supplies, relays, switches, PLCs and others, classified in this way? The answer is very simple: because they are devices that mount onto a metal guide-rail normally placed inside electrical panels or enclosures.
The DIN rail has a history spanning more than a century, but it was only in 1950 that it was developed into the current standards by the German institution Deutsches Institut für Normung, precisely DIN.
There are three main types of DIN rails (in turn divided into subtypes with different dimensions):
- the most widely used is the one called Omega (also known as “hat-shaped” or type O);
- then there is the C-section rail;
- and the G-section one (the name is linked to the “shape” of the rail itself).
The DIN rail can be perforated, pre-drilled or completely sealed. Several devices are mounted on a DIN rail, which are connected to each other by special terminal blocks, creating modular circuit blocks.
Advantages of DIN rails
The advantages of DIN rails are considerable: first of all, design is simple, as is wiring. Furthermore, installing or removing devices is easy and quick. DIN rails help save space, with the possibility of having fewer devices that are also, above all, more compact.
Another advantage of DIN rails not to be underestimated is the interchangeability of devices: thanks to the standardization of DIN dimensions, products from different manufacturers and brands can easily be used in the same system.
DeltaPSU DIN Rail Power Supplies
The most widely used devices on a DIN rail are certainly DIN Rail Power Supplies, which are used above all in the industrial field, particularly in automation or panel building.
Delta Electronics, distributed in Italy by Consystem S.r.l., has an extremely wide portfolio of DIN Rail Power Supplies, incredibly rich in functions and features, ideal for every need, field of work and market sector.
Main features of DeltaPSU DIN Rail power supplies
The first, very important, peculiarity of DeltaPSU DIN Rail power supplies is that they are all power supplies certified according to the specific target application, in order to guarantee, first and foremost, safety. There is, for example, a product category that is ATEX certified, that is, for use in explosion-risk areas, or again, a family of power supplies for maritime use, compliant with the regulations set out by Maritime DNV GL.
Another noteworthy factor, no less important given the increasingly widespread attention to the environment, is that DIN rail power supplies are Green and have high efficiency >90%.
All of Delta’s DIN Rail power supplies have a universal AC input voltage range (Input Voltage Range: 85/90Vac-264Vac for single-phase, 320-575Vac for three-phase). They offer various ranges of rated output voltage (Output Voltage). Indeed, numerous types of DIN rail power supplies are available: 5Vdc, 12Vdc, 24Vdc (24Vdc DIN power supply) and 48Vdc for various output power ranges (Output Power) ranging from 7.5W up to 960W (with many different fractional steps). The output current (Output Current) ranges from 0.83A up to 40A.
Finally, but no less essential, one of the many strengths of Delta Electronics’ range of DIN Rail power supplies is the extremely reduced and compact dimensions (and weight) of all models, among which we also find even slimmer power supplies: in some cases power supplies are as small as just 75 x 21 x 89.5 mm!!!
Among the other features: cold start down to -40°, Power Boost (the ability to deliver up to 150% more power at start-up), Advanced Power Boost (intelligent failure management with multiple connected loads), Smart monitoring functions, FPC, and also: models with LCD display, LED indicators, models for single-phase, two-phase or three-phase input voltage (Phase Input 1, 2, 3).
Thanks to all these features, with Delta’s wide range of DIN rail power supply models, it is possible to cover an exceptional and extraordinary variety of applications. Even the most demanding technician will certainly find the DIN Rail power supply suited to their project!
