for PL 1000 only 230 V (not 230-240 V)
The light sources are designed for use at temperatures of up to 40 °C. Using them at high temperatures, however, dramatically reduces the life of the lamp and the electronic components.
For optimum operation, the ambient temperature should not exceed 25 °C.
DESCRIPTION
By purchasing this product, you have obtained a high-quality cold-light source,
which you can use wherever you need a lot of light without generating heat. It
is used for specimen illumination for microscopes. In most cases, fiber-optic ring
illuminator are attached that are mounted to the microscope objective. Goosenecks or flexible light guides can be attached as an alternative.
In this case, halogen cold-light reflector lamps (1) of different power levels are
used as illuminant. Using a special heat-absorbing filter (10), the heat is reflected, whereby the required visible light
passes through in its entirety. To dissipate the generated heat, an axial fan is
installed for all types except for the PL 1000. The illuminant is powered by a
state-of-the-art electronic switched-mode power supply that was specially
developed for such cold light sources. To switch on the device, turn the knob (7
or 12) clockwise form minimum setting to maximum setting. Turn it completely
to the left until a clicking sound can be heard to switch off the cold-light source.
This adjusting button is used to electrically control (dimmed) the cold-light source. However, this also changes the color temperature so that the light appears
more reddish in the dimmed state than in the maximum setting. If a constant
color temperature is required, the light must be dimmed mechanically using a
hole matrix aperture.
All versions with the letter “B“ in the model code feature an aperture wheel in
addition to the electronic brightness control. This wheel can be used to control
the quantity of light from 100% up to approx. 1% with constant color temperature. In addition, it is of course possible to use electronic control, although the
color temperature would then change again. Using the slide-in filter (4) allows
for inserting various filters into the device.
All versions with display (19) (identified by the letter “D“ in the model code)
show the current color temperature during electrical dimming. In addition, fan
and lamp failure are shown on the display.
All versions with an “F“ in the model code feature a swing-in device (18) at the
front for a filter (daylight filter for a color temperature of approx. 5600 K).
“Ra“ in the model code means that the light source features a DIN socket for
the remote control (20). This allows for analog dimming of the light source and
switching it to standby mode.
“Rs“ in the model code means that the light source features a 9-pin RS232 DSub socket (21). It allows for dimming the light source via an RS232 interface
and switching it to standby mode. If a display is also available, it is possible to
query the address assignment and other RS232 data.
The versions “Rs“ and “Ra“ cannot be installed in a device at the same time.
PL 3000R (B) features an analog remote socket that allows for connecting a
hand-held remote control or a serial interface for computer-supported control of
the light source (accessories: RS232 interface and remote control; for pin
assignment see the accessories description). In addition, a PFC (power factor
correction) switched-mode power supply is used which allows for worldwide
operation of the light source (100–240 V) and which is also free of ripple.
