| Q.
How to specify a power
supply? |
A. The following are the mechanical considerations when
choosing a power supply:
|
Thermal
Considerations: |
| What is
the thermal environment of the power supply?
Ambient temperature & temperature rise within the
product. What options do you have to keep the
power supply running within its intended operating
range. No airflow, convection airflow, forced
airflow. Conduction? |
 |
|
Electrical
Considerations: |
| DC input
or AC input. What is the desired range of the
input? If it is Switching AC input model, the
approval agencies may eventually require you to have
harmonic correction. If a linear power supply will
fit the specifications you desire, you will not be able
to use the same model for worldwide input. How
many output voltages are required? How tightly do
they have to be regulated? What is the duty cycle
of each output and how do they relate to each
other? What is the output peak requirement for
each output and for what duration? |
|
|
Logic
& Controls: |
| What
signals do you require from the power supply such as
"power good/fail"? What signals do you
want to send to the power supply such as "remote
enable" or "margin"? Do you need a
voltage adjustment pot or remote sense on one or more
outputs? Do you need "Standby Voltage"
to keep a processor idle until called upon to "wake
up" by the operator? |
|
|
Approval
Agencies: |
| If your
product is to eventually be sold in Europe, you will
want to consider the CD mark. If it is only going
to remain in the United States, you can probably do with
the appropriate UL mark. |

| Q. What is POST? |
| A. POST is a new innovation design to help users easily
determine if the power supply working properly. Simply
plug-in the AC power cord and press the POST button, the
internal embedded chip will generate a signal to perform self diagnostic.
If all internal components and circuitry perform properly, the
power supply will activate the cooling fan and light up the
GREEN power-on status indicator. It tells user there is
no problem found inside of power supply. |
