How to Choose Industrial Machinery & Equipment Power Supply?

Since the birth of the Industrial Revolution, the world has witnessed quite a long list of innovations and inventions that have played very important roles in affecting as well as facilitating our lives.


The economic effects of machinery manufacturing continue to extend throughout the global economy since this is the industry that feeds others such as the agriculture industry, food, and beverage industry, the aerospace industry, construction industry, automotive industry, energy industry, mining industry, and the list goes on.


The machinery manufacturing industry is supplying other manufacturing and service industries with indispensable; cost-healing; labor, time, and energy-saving; cutting-edge technologies.

The highly competitive nature of this sector and companies’ devotion to technological innovation brings on a sweet challenge for OPTIMAL Mechatronics to work even harder and supply its customers with efficient, functional, and economical products, industry-specific machinery, and services.


A very good example of our high-quality work is the huge Casting Racks that we have manufactured for an industrial ceramics business.

For example How to know the rating of Using the 3D printer  power supply


All 3D printers have a power supply that converts high voltage AC (alternating current) to low voltage DC (direct current). This power supply has a maximum rating that it is unable to exceed. With that rating in mind, we can figure out the absolute maximum amount of electricity that a 3D printer can use.

The total power consumption


In the case of a “normal” 3D printer it will be:

  • 100W for the heated bed
  • 40W for hotend
  • 45W for motors y drivers
  • 10W electronics in general

We have a total power consumption of 205W.

Security factor


Having done the previous sum with a result of 205W we may be tempted to use a 200W source, or a 240W source, but this would be a mistake. Since it would take us to a damaged source in a matter of minutes, hours or days. Why would this happen to us? For not having taken into account any safety factor.


How to calculate the safety factor?

We are not going to go into excessively technical aspects, since this is something very important in the industry, we are simply going to comment on some points to consider:

Time of continuous use

Are we going to size our printer for prints of many hours? Generally yes, since impressions usually take hours and even days to complete.


Type of load

It is not the same to feed a stable resistance, that a more complex load, 3D printers have many oscillations in the load, turn on and off the bed abruptly, and have components with inductive loads such as motors so that the power supplies suffer more with this type of charges than with a simple LED.


Critical application

Does something happen if the power supply fails? A military or medical equipment cannot fail, there are lives at stake, but a 3D printer must not fail either, although there are no lives at stake. Often we find tight deadlines to meet, so it is not convenient to skimp because it can cause losses and delays, being this is more important for 3D printers designed for professional use.


Room temperature

El calor es uno de los factores que más castiga a la electrónica, la zona en la que tengamos instalada la fuente de alimentación influye en su vida útil, generalmente se instalan en un lateral manteniendo la refrigeración y evitando que estén sometidas al calor generado por la cama caliente.


Generally, manufacturers of power supplies recommend a safety factor of 0.8. Or what is the same, that the working power does not exceed at any time 80% of the nominal value of the power supply, we recommend using a slightly greater factor so that our source lasts for years and years, even working at high temperatures.


0.6 is the value we recommend

In the previous calculation, we have obtained a working power of 205W, divided by 0.6, it gives us a power of 341.6W, so we will choose the power supply above 350w.
