It Is Important To Select Correct Enclosed Power Supplies

For those that don’t know, there is a fundamental difference between open power supplies and enclosed power supplies, although the differentiation is quite straight-forward and rather a simple one:

The one power supply has an open frame, whereas the other has an enclosed frame which protects it from the elements. These are the two fundamental differences, and the options are endless.

You might ask the question – why would someone choose the open-frame power supply instead of an enclosed power supply, whilst risking damage to the supply and/or  being shocked? We need to take one important factor into consideration, and that is cooling off of the system.

Bear in mind that an open-framed system cools off a lot faster than an enclosed-framed system would.

Some of the choices of an open-framed system include linear, single or multiple-output as well as vital medical switching.

Enclosed power supplies offer high quality enclosed universal AC input switching power supplies, which have both over- current and short-circuit protection.

With enclosed power supplies, the voltage is adjustable – this is in the region of +/-10%.

It is imperative to only ever use professionals to connect the primary voltage which has to be carried out by a qualified electrician for safety purposes.

Enclosed power supplies offer “over current” protection; should the connected circuit draw an excessive amount of current the power supply will simply shut off. When the system is in this mode the green LED light will either glow very dimly or not at all.

Once you reboot the system this will reset the fault by temporarily removing the AC power to get it up and running once again.

Five Useful Things You Need To Know about Your Surge Protection Device

Don’t let surges ruin your expensive and sensitive equipment. Being forearmed is smart – ensure you do the shrewd thing by investing in a surge protection device.

But not everyone understands exactly how a surge protection device actually works; for those individuals that are keen to learn more and would like to become familiar with these devices, here are five useful things you ought to know about surge protection to gain maximum benefit at all times.

  • In a nutshell, your surge protection device which could also be referred to as a surge diverter or surge suppressor, has been created specifically to safeguard electrical devices from spikes in voltage. The general idea is for the surge protector to reduce and limit the voltage that is supplied to any electrical device either by shorting any unwanted voltage to the ground or by blocking it altogether – always above a safe threshold.


  • For those individuals and businesses that live in an area exposed to high levels of lightning, a surge protection device is not a luxury but rather a necessity.


  • Your surge protection device is an inexpensive method to ward off damage or disruption to all that expensive electronic equipment you invested in.


  • Downtime is also drastically reduced by making use of surge protection devices.


  • There are so many theories on what element, what topology, and the deployment of specific technology used to produce the best SPD for diverting surge current; do your homework to find the one that fits your needs best.


Some of the causes of SPD devices are primarily caused by installation errors, the misapplication of a product to a voltage rating and continued over-voltage incidents.
