Programmable Power Supplies
Programmable
Power Supplies from simplypowersupplies.com
are available in Linear and Switched Mode formats from
30W up to 32kW, and in bench top or 19" rack mounting
styles. Most units have analogue control of voltage
and current values as standard enabling the user to
set the voltage level and the current limit remotely,
and offer the option for serial communications to a
host device using IEE488.2, GPIB, RS232, RS485 or USB.
 Programmable
Power Supplies are also referred to in the industry
as Variable Power Supplies, Laboratory Power Supplies
or Bench Power Supplies. Essentially these terms describe
the same equipment and refer to a device which can be
plugged into the AC mains and produces a fully controllable
yet variable dc voltage. For many applications (for
example in research and development) there is also a
need for parameters to be limited so the current limit
on these units is also controllable, as well as additional
overvoltage protection to prevent the voltage being
accidentally increased beyond a predetermined level.
Programmable Power Supplies are used in a variety of
applications and industries, including; universities
and educational establishments, research and development,
laboratories, automotive, space technology, aerospace,
oil exploration, renewable energy, electronics, and
production testing in many other industries. A common
application is automatic test engineering (ATE) where
these variable power supplies are rack mounted in 19"
cabinets, controlled by an automated program and then
monitored remotely so that the data for the items under
test can be logged for pass/fail decisions and for future
reference.
Remote control options representing 0-100% of voltage
or current range include 0-5Vdc, 0-10Vdc, 0-20mA, 4-20mA
or resistance programming. Many different serial remote
control options exist but for test and measurement applications
the most commonly used is GPIB/IEEE488.2 using the LabVIEW
driver, as this has become almost a default standard
within many laboratory environments. Using this system
up to 31 devices can be controlled or monitored from
a single controller.
The beauty of the Programmable Power Supplies available
from simplypowersupplies.com is the sheer number of
variations that are on offer. Many different voltage
and current ranges are available from low voltages of
0-6Vdc through to units offering 0-1000Vdc. The current
ranges are also scaleable from a few amps up to 0-600A
meaning there is almost always a suitable solution available.
In addition to the standard models we can also offer
ruggedised versions of some units, so for applications
where vibration could be an issue (if the unit is mounted
on a vehicle for example) we can provide a more suited
solution.
