COUTION
WARNING
Before operating model 3063R/4063R, please check input voltage is correct and the
ventilation holes are not been locked.
After pressing the "SWITCH ON" button, please check the operation of
ventilation fan to avoid the instrument being over heated.
A. Setting the output voltage and output current
[NOTE]
The power supply can automatically operate between constant voltage and constant
current by quickly responding to the load changes, when the C.C. LED(Red) light up,
the C.V. LED (green) will be off and vice versa .
DC POWER SUPPLY
B. Operation Modes of 3063R
The power supply can be operated alone or connected two or more units in serial to
obtain a higher voltage (Max. 240V). or in parallel to obtain a higher current (Max. 24A)
WARNING
1. Independent Mode:
The master and the slave output of 3063R can be used independently to generate
voltage and current.
To operate 3063R under independent mode. Set the master output voltage/current and
slave output voltage/current as described in section A and B, model 3063R.
Never connect GND (green) terminal to any place under this operation.
WARNING
Never switch this istrument between independent mode and tracking
mode when this instrument is connecting with an application circuit
beacuuse this might cause damage to the unit.
DC POWER SUPPLY
2. Serial Tracking Mode:
[NOTE] When 3063R was operated under this mode. The master output is serial
connected to the slave output automatically. The outputs are generated from the "+" of
the master output terminal (7) and the “－" of the slave output terminal (20). The
output voltage will be TWICE of the master output setting voltage and the current will
be the same as the master setting current.
2-1. Set the function switch (25) to serial mode, the power supply 3063R will be under
serial operation mode and the yellow LED (14) will light up.
2-2. Turn the slave current adjustment knob (19) clockwise to maximum.
2-3. Set the master output voltage and current as described on section A, 3063R model.
2-4.The output terminal will be "+" of the master and “－" of the slave terminals.
3. Parallel tracking Mode:
[NOTE] when 3063R is operated under "PARALLEL" mode. The master output
terminals are parallel connected to the slave output terminal automatically. The parallel
output are generated from the master output for both "+" and “－" termimals. The
output voltage is the same as the master set value and the output current is twice the
master output current setting.
3-1. Set the output mode switch (25) to parallel mode and the red LED (15) will light
up.
3-2. Be sure to turn both of the voltage adjustment knob (18) and current adjustment
knob (19) of the slave output clockwise to maximum.
3-3. Set the master output voltage and current as described on section A, model 5003.
3-4. The output terminal can be the "+",”－" terminals of the master output or "+"
master and “－" terminals of the slave output .
4. Serial mode:
The power supply 3063R can be connected two or more units in series to obtain a
higher voltage output (Max. 240V).
4-1. Set all the 3063R which would be connected in serial operation under serial
tracking mode as described on section 2.
4-2. Connect the “－" slave output terminal of the unit 1 to the "+" master output
terminal of the unit 2.
4-3. The output voltage terminals will be the "+" master output terminal of the unit 1
and the “－" slave output terminal of the unit 2.

WARNING
The maximum output voltage of the system should never exceeds 240V.
4-4. If the connected units are more than 2. Connect the "+" master output terminal of
the 3rd unit to the “－" slave output terminal of the unit 2. etc. The output voltage of
st
the system will be the "+" master output terminal of the 1 unit to the “－" slave output
terminal of the last unit.
DC POWER SUPPLY
5. Parallel Mode:
The power supply 3063R can be connected two or more units in parallel to obtain a
higher current output (Max. 24A only).
5-1. Set all the 3063R which will be connected in parallel operation under parallel
tracking mode as described on section 3, parallel tracking mode and adjust all units to
the same output voltage
5-2. Parallel connected the "+" master output of all unit and “－" slave output of all
units in the system.
5-3. The output voltage of the system is the same as the units been set. The output
current of the system is the sum of each unit.
WARNING
The Max. output current of the parallel system should never exceeds
24A.
6. Fixed 5V/3A output:
This is the standard 5V/3A-power output for use of TTL logic circuit. When the load
exceeds 3A, the red overload LED will light up. The output voltage will lower and the
power supply will be under C.C. mode.
C. Operation Modes of 4063R
WARNING
Never switch this istrument between independent mode and tracking
mode when this instrument is connecting with an application circuit
beacuuse this might cause damage to the unit.
To set the output mode switch(25) at:
1. Independent Mode: To set the switch at " IND " position.
2. Serial Tracking Mode: To set the switch at " SER " position.
3. Parallel Tracking Mode: To set the switch at " PAR " position.
