Sola has a broad range of standard power supplies to suit almost
any industrial application. Updated approvals and user friendly
features make power system design easy. The product line includes
one of the broadest ranges of DIN Rail and linear-based power
supplies in the marketplace. The DIN Rail power supplies products feature full
CE compliance (including all the elements of CE design engineers
need to worry about: safety/LVD, EMC, and ingress protection).
UL 508 approvals eliminate derating in UL 508 listed panel systems.
Global inputs are available for installations around the world.
|
Sola also offers a three phase input option on many of the SDN DIN Rail power supply products that
convert 380/480 three phase directly to 24 VDC. They provide extremely stable, regulated
low voltage without the need for a step down transformer saving space and money. For the
popular SL linear line, Sola leads the market by replacing the time consuming solder
connections with screw terminals. Ease-of-use is now combined with the economy and
extremely low noise. |

Sola has provided both linear and switching technology products for many years. As a
leading supplier of power products to the industrial market, both technologies are still
important. Switching technology (most of Sola’s DIN Rail line) is the predominant
method of AC-DC conversion for almost any type of electronic system sold today in the
world, from PLC’s to desktop PC’s.
The small size, lightweight and high efficiency of the switching products give them
significant advantages over the linear technology products (Sola’s SL and 81/83
series). Sola switching products provide well filtered and regulated DC of typically less
than 1% deviation from the nominal output voltage.
|
|
Linears are about 50% efficient while
their switching counterparts are typically over 80% efficient. Switchers are light enough
to mount on a DIN Rail, while only the smallest linears are capable of being securely
mounted to a DIN Rail. Linears are still popular today because they do provide very tight
regulation (<.01% typically), almost perfectly clean DC, fast transient response and
their low component count helps provide a lower material cost for its user.
|
| Linears
are typically open frame because of the excessive heat dissipation
from their low efficiency. Sola’s industry standard linears,
however, are available with optional covers for safety. Most
linears, except for Sola’s SCL series, are recognized to
UR 1950 and cannot meet the stricter temperature requirements
of the UL 508 Listing, such as with Sola’s switching DIN
Rail power supplies. |

1. Gather the required information.
• Input voltage and frequency?
• Wattage needed?
• Number of outputs?
• Voltage of each output?
• Amperage of each output?
• Don't forget to take into account the
peak loading of each output.
2) Calculate the power (wattage) of the DC
power supply you need. If more than one
output is required, do the following calculation:
- Multiply the Voltage times the amperage of each output
to calculate the wattage of each output. Next, add together
the wattage of each output to get the total wattage for
the supply.
3) Determine which models from the Power Supply
Selection Chart meet all of the required
specifications.
4) Download the specifications sheet pdf from the
appropriate product page.
5) Check the mounting style, connections and
physical size of the power supply to ensure
its
suitability for the intended application.
6) Check for applicable safety approvals for the
country and application the power supply
will
be used in.
