NOTICEBEFOREOPERATION
1. Unpack the instrument:
After receipt of the instrument, immediately unpack and inspect it for
any damage which might have been sustained when in transportation or
shortage of accessories. If any sign of damage and shortage of
accessories are found, immediately notify the dealer.
2. Environments:
Normally, operational temperature of the instrument is 10°C to 40°C
90%R.H.
(50°F to 104°F). Operation of the instrument outside of this temperature
range may cause damage to the circuits.
3. Check the Line Voltage:
The instrument can operate on any one of the line voltages when in the
below table by inserting the line voltage selector plug in the
corresponding position on the rear panel.
Before connection the power plug to an AC line outlet, be sure to check
that voltage selector plug is set in the correct position corresponding to
the line voltage.
Selector Line Voltage Fuse
115V 100~125V 50/60Hz 6A
230V 220~240V 50/60Hz 3A
4. Hints for operation:
(1) Never place heavy objects on the instrument.
(2) Never place a hot soldering iron on or near the instrument.
(3) Never insert wires, pins or other metal object into ventilation fan.
(4) Never move or pull the instrument with power cord or output lead,
especially never move instrument when power cord or output lead is
connected.
(5) If the instrument is used in a manner not specified by the manufacturer,
the protection provide by the equipment may be impaired.

WARNING!
The following precautions must be observed to help prevent electric
shock.
1. When the instrument is use to make testing. There is always a certain
amount of danger from electrical shock. The person using the
instrument in such condition should be a qualified electronics technician
or otherwise trained and qualified to work in such circumstance.
2. Do not operate the instrument with the cover removed unless you are a
qualified service technician.
3. The ground wire of the 3-wire AC power plug places the chassis and
housing of the instrument at earth ground. Use only a 3-wire outlet, and
do not attempt to defeat the ground wire connection or float the
instrument to do so may pose a great safety hazard.
4. Do not obstruct the ventilation holes in the rear panel. As this will
increase the internal temperature.
5. Never apply external voltage to the output terminal of the instrument.
6. The instrument is designed for INDOOR USE ONLY.
7. This instrument has been evaluated to INSTALLTION CATEGORY II,
POLLUTION DEGREE 2.

OPERATIONINSTRUCTION
The power supply 7033 can be operated alone or connected two or more
units in serial to obtain a higher voltage rating (Max. 240V) or in parallel to
obtain a higher current (Max. 24A).
WARNING!
Never connected GND (○
A) terminal to any place on this operation.
1. Independent Mode:
The CH1 and the CH2 output of 7033 can be used independently to
generate voltage and current.
To operate 7033 under independent mode. Set the CH1 output
voltage/current and CH2 output voltage/current as described in section
A and B.
2. Serial Tracking Mode:
[NOTE] When 7033 is operated under this mode. The CH1 output is
serial connected to the CH2 output automatically. The serial output is
generated from the "+" of the CH1 output terminal (○
6) and the "－" of
the CH2 output terminal (○
21 ). The output voltage will be TWICE of the
set CH1 output voltage and the current will be the same as the CH1
setting current.
2-1. The CH1 voltage adjustment knob (○
9) the power supply 7033 will
under serial operation mode and the green LED (○
14 ) will light up.
2-2. Turn the CH2 current adjustment knob (○20) clockwise to maximum.
2-3. Set the CH1 output voltage and current as described on section A.
2-4.The output terminal will be "+" of the master and "－" of the slave
terminals.

12
3. Parallel tracking Mode:
[NOTE] When 7033 is operated under "PARALLEL" mode. The CH1
output terminals are parallel connected to the CH2 output terminal
automatically. The parallel output is generated from the CH1 output for
both "+" and "－" terminals (or CH2 output terminal) the output voltage is
the same as the CH1 set value and the output current is twice the set
CH1 output current.
3-1. "PULL" the current adjustment knob of the CH1 output (○
11 ) to set
the 7033 operate under parallel mode and the green LED (○
14 ) will
light up.
[NOTE]
Output mode switch can be adjusted at the “IND”, “SER”, or “PAR”
position.
3-2. Set the CH1 output voltage and current.
3-3. The output terminal can be the "+","－" terminal the CH1 output,
maximum to 6A.
4. Serial mode:
The power supply 7033 can be connected two or more units in series to
obtain a higher voltage output (Max. 240V).
4-1. Set all the 7033 which would be connected in serial operation under
serial tracking mode as described on section 2, serial tracking
mode and adjusts to the same output.
4-2. Connect the "－" CH2 output terminal of the unit 1 to the "+" CH1
output terminal of the unit 2.
4-3. The output voltage the system will be the "+" CH1 output terminal of
the unit 1 and the "－" CH2 output terminal of the unit 2.

13
4-4. If the connected units are more than 2. Connect the "+" CH1 output
terminal of the 3rd unit to the "－" CH2 output terminal of the unit 2.
etc. The output voltage of the system will be the "+" CH1 output
terminal of the 1st unit to the "－" CH2 output terminal of the last
unit.
WARNING!
The maximum output voltage of the system is never exceeds 240V.
5. Parallel Mode:
The power supply 7033 can be connected two or more units in parallel
to obtain a higher current output (Max. 24A only).
5-1. Set all the 7033 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 "+" CH1 output of all unit and "－" CH2
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.
5-4 Output is only at CH2, Maximum to 6A.
WARNING!
The Max. output current of the system never exceeds 24A.
6. Fixed 5V/3A output:
This is the standard 5V/3A-power output for use by TTL logic circuit.
When the load exceed 3A, the red overload LED will light up. The output
voltage will be lower and the power supply will be under C.C. mode.
