46D Deuterium Lamp Power Supply0 pages

The OL 46D Deuterium Lamp Power Supply is specifically
designed to operate the Gooch & Housego OL UV-40 and
OL 752-12 Deuterium Standards of Spectral Irradiance,
and the OL 440-8-OH Ultraviolet Integrating Sphere
Standard of Spectral Radiance.
These deuterium
standards must be operated at the same current used
during the calibration in order to realize the calibration
accuracy. Accordingly, the OL 46D provides a constant
lamp current of 300 mA with a ± 0.1% accuracy. It is also
an ideal current source for the deuterium lamp used in the
OL 740-20 and OL 750-20 Source Attachments.

SPECIFICATIONS
Output Current .................................................................. 300 mA ± 0.1 %
Filament Voltage (starting).......................................................10 V (1.2 A)

The OL 46D features complex automatic lamp starting and
operating supplies. When the supply is turned on, a
starting voltage is supplied to heat the filament. After
approximately 20 seconds, the initial regulated filament
voltage is reduced by 30 %, and the high voltage circuit is
switched on. Following the high voltage pulse striking the
lamp arc, a precision DC lamp current is established. The
circuit is designed to provide a stable, reliable discharge
without subjecting the lamp to undue stress. An arc status
indicator on the front panel indicates operation of the lamp
arc, and an elapsed time meter accumulates lamp hours
only when the status indicator is lit.

Filament Voltage (operating) .....................................................7 V (1.0 A)
High Voltage Starting Pulse .............................................. 600 volts (peak)
Lamp Voltage..................................................................... 80 volts ± 10 %
Regulation (line and Load) ............................................................± 0.05 %
Input Voltage........................................................ 90 – 265 VAC, 50/60 Hz
Weight ................................................................................... 4 lbs (1.8 kg)

The OL 46D regulated power supply maintains its
accuracy during power line transients of ± 10%. The
supply will also operate over a ± 10 % load variance, which
allows it to accommodate different operating voltages from
one lamp to another.
