IMPORTANT
SAFETY PRECAUTIONS
This power supply unit is only for use with our halogen lamp housings.
1. A power supply is a precision instrument. Handle it with care and avoid subjecting it to sudden or severe impact.
2. Do not use the power supply where it is subjected to direct sunlight, high temperature and humidity, dust or
vibrations.
3. For operation environmental conditions, see chapter 5, “SPECIFICATIONS” on page 8.
4. Always use the power cord provided by us. If no power cord is provided, please select the proper power cord by
referring to the chapter “PROPER SELECTION OF THE POWER SUPPLY CORD” at the end of this instruction manual.
5. Always set the main switch on the power supply unit to “ ” (OFF) before connecting the power cord to the wall
outlet.
6. This power supply is air-cooled so its surfaces become hot during operation. When installing it, leave spaces of
more than 10cm around it. Also make sure to distribute cables away from the power supply.
7. To avoid potential shock hazard, make sure that the power cord is properly grounded.
8. Be sure to set the main switch to “ ” (OFF) and unplug the power cord before replacing the halogen lamp bulb.
9. The surfaces of the lamp housing will become extremely hot. When installing the lamp housing, be sure to allow
ample free spaces around and in particular above and below the lamp housing.
10. The standard service life of the lamp housing is eight (8) years of use or 20,000 hours of total power ON period,
whichever is the shorter period.
For details, see Inspection Sheet on pages 18, 19.

1Connecting the Cables and Cords (Fig. 1 & 2)
! The cables and cords are vulnerable when bent or twisted. Never
subject them to excessive force.
! Make sure that the main switch is set to “”(OFF) before connecting
cables and power cord. Otherwise equipment failure may result.
1. Insert the hand switch plug @ into the connector ².
2. Insert the lamp housing plug ³ into the connector |.
! Always use the power cord provided by us. If no power cord is
provided with the microscope, please select the proper power
cord by referring to chapter “PROPER SELECTION OF THE POWER
SUPPLY CORD” at the end of this instruction manual.
3. Insert the power cord plug ƒ into the connector ….
4. Insert the power cord plug † into the wall power outlet ‡.
! The power cord should be connected to a grounded, 3-conductor
power outlet. If the power outlet is not grounded properly, we
can no longer warrant the electrical safety performance of the
equipment.
! If a cable or the power cord comes in contact with the lamp socket
or the surroundings, the cable or cord may melt down, causing
electric shock hazards. Be sure to distribute the cables at enough
distance from the lamp housing and power supply unit.

1Voltage Indication (Fig. 3 & 4)
1. Ensure that the brightness control knob @ is set to MIN (lowest voltage)
then set the main switch ² to “ I ”(ON). (The POWER LED ³ lights up.)
2. Turn the control knob @ toward MAX (highest voltage) to increase the
voltage intensity and brighten the illumination.
} The position marked indicates the position with which daylight suit-
able for photography can be obtained when an LBD filter is engaged
in the light path.
Hand Switch Operation
} When the hand switch is connected (the REMOTE LED | lights), the
brightness control knob @ is defeated but the brightness control knob
ƒ of the hand switch is activated.
1. Press the lamp ON-OFF switch … and adjust the brightness with the
control knob ƒ.
2. To turn the lamp OFF, press the lamp ON-OFF switch … again.
# When the REMOTE LED | is lit, the hand switch in standby mode
and consumes about 2.5 W of power.
When the equipment is not to be used for a long period of time, be sure
to set the main switch ² to “ ” (OFF).

1Controlling the Amount of Light According to
External Analog Voltage (Fig. 5)
} The amount of light can be varied between MIN and MAX by applying
a DC voltage input from 0 to 5 V.
1. Connect a DC power supply as shown in Fig. 5. Do not turn on the power
supply yet.
2. Set the main switch to “ I ” (ON).
3. Apply the external analog voltage.
DC voltages from 0 to 5 V correspond to the light amount from MIN to
MAX.
# The external wiring should have a wire gauge of AWG28 (0.1 mm2)
or more.
# Do not apply voltage above 5 V DC. Doing so will cause the unit to
malfunction.
# Do not apply the analog voltage before setting the main switch to
“ I ” (ON). Doing so will cause the unit to malfunction.

} The lamp can be turned off by shorting pins 4 and 2 of the DIN 8-pin
connector.
# The external wiring should have a wire gauge of AWG28 (0.1 mm2)
or more.
# The external contact should be fully capable of switching 10 mA on
and off.
# When the lamp is to be turned on/off with the open collector,
connect the emitter to pin 2.
} The amount of light can be controlled between MIN and MAX by con-
necting an external VR.
1. Connect a VR as shown in Fig. 7.
2. Set the main switch to “ I ”(ON).
3. The amount of light is minimized when the voltage at pin 1 is 0 V and
maximized when it is +5 V.
# The external wiring should have a wire gauge of AWG28 (0.1 mm2)
or more.
# Use an external VR of 10kΩ 0.1 W.

} Detects failed lamp and gives output alarm signal.
When lamp is normal: Open collector output is “ON” (i.e. there is a short
circuit between pins 4 and 7).
When lamp fails: Open collector output is “OFF” (i.e. there is an
open circuit between pins 4 and 7).
# The external wiring should have a wire gauge of AWG28 (0.1 mm2)
or more.
# External voltage connected to pin 4 should be negative and that
connected to pin 7 should be positive.
