Power supply is among the most important components
of any industrial application. But they do not get the attention that
they need. Most of the time engineers do not understand the
considerations that go into choosing the correct power supply and
selecting a product that is within their budget. When considering a
particular power supply for an industrial application, it is important
for the designer to have an understanding of the steady state of output
parameters and the electrical and physical environment that the
equipment will be operating in.
Motors, solenoids and relay controls will need higher
level of currents to be used and for a continuous operation. Thus, it
is important to examine the magnitude of the pulses and specify a power
supply that can provide such current continuously. In most of the
industrial environments, the AC line not only feeds the power supply but
also drives the larger equipment. This is the reason why power sags and
surges are quite common. Any high spikes on the AC line can greatly
damage the power supply. Even though the unit can pass the bench
testing, it will lead to long term damage to capacitors and
semiconductors that can lead to failure after just a few months of
usage. In order to prevent loss of DC power during sags, it is important
to specify a power supply like OEM standard AC DC ups that has a wide AC input range.
When mounting the power supply, it is important to
make sure that there is adequate space around the product to allow air
to circulate. It is important not to block off heatsink fins with
mounting brackets and restrict the air inlet or the exit from the fan
cooled units. Thus, one can easily see the benefits of hiring a power
supply company who can help design and provide power supply solution
that is customized for your industrial needs. it is important to do your
research and find the best one that suits your budget as well.
