RADIOMETRIC POWER SUPPLY
model 68830 Power supply
was designed to meet the
needs of the researcher who demands a highly regulated
source of high current for proper operation of light sources.
These sources are from tungsten lamps for VIS-NIR radiation
or from ceramic glowers for IR radiation. Constant current
operation of these sources of radiation is required whenever
a radiometric measurement is being made or whenever a highly
stable light output is needed.
The light sources will be operated in constant current mode
by the Oriel
Model 68830 Power supply
with the output
voltage being dependent on the load's impedance. A constant
current Power supply
regulates current even into a short
circuit, and the model 68830
is such a Power supply
. It is
also safely limited to 2d amperes or 300 watts. Any
resistive load which operates between 0-20 amperes and 0-50
volts, and dissipates less than 300 watts may be connected
to the 68830 Power supply
does not only provide a controlled
source of current to such a wide variety of loads. It also
contains circuitry to allow for viewing the output current,
the output voltage, and the output power. There is provision
for remote monitoring of these output parameters. Remote
capability also includes an input for external control,
modulation, or photofeedback.
Radiometric Power supply
was designed to be a
reliable and efficient source of direct current The main
section usesxiff-line switching technology with
the resultant increase in power conversion efficiency,
reduction in weight, and wide input mains operation.
