Safety Summary
The following safety precautions apply to both operating and
maintenance personnel and must be observed during all phases
of operation, service, and repair of this instrument. Before applying
power, follow the installation instructions and become familiar with
the operating instructions for this instrument.
GROUND THE INSTRUMENT
To minimize shock hazard, the instrument chassis and cabinet must
be connected to an electrical ground. This instrument is grounded
through the ground conductor of the supplied, three-conductor ac
power cable. The power cable must be plugged into an approved
three-conductor electrical outlet. Do not alter the ground connection.
Without the protective ground connection, all accessible conductive
parts (including control knobs) can render an electric shock. The
power jack and mating plug of the power cable meet IEC safety
standards.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE

current for high precision.
These power supplies are ideal for trouble shooting circuit boards or
devices which require two or three different input voltages such as 3
V or 5 V, 12 V and 1-36 V. This power supply can provide 3 outputs
at the same time.
All three outputs are fully isolated so different cross connections of

1.2 Connection and Operation Procedure
1. Check the rating label and plug in to AC mains.
2. Switch on the power supply and the LCD display should
be on at the same time.
3. The (CV) icon should be shown on the display.
4. Turn to current volume knob (6) to maximum clockwise if
you do not require lower Current limiting value, otherwise
do the preset the (CC) limiting procedure.
5. Set your desired output voltage and then turn off the
output terminal by push button (7).
6. Connect to your load positive to positive and negative to
negative.
7. Turn on the output terminal again and check if display
shows (CV).
8. If display shows (CC), either your preset current limiting
value is too low or your load requires more voltage and
current. You need to re-access the voltage and current
requirement of your load and increase the voltage or
current accordingly until (CV) appears.
1.3 Connecting the 3 outputs
(Using the 1405, 1-36 V, 0.25-3 A as an example)
All the three outputs are fully isolated from ground and with each
other so that it is possible to make cross connections to power a
circuit board or device that requires for example: +3 or +5 V, +12 V
or -12 V and 1-36 V as shown in Figure 2.

This power supply is designed to operate as a constant voltage
source or as a constant current source. Automatic crossover to
either mode of operation occurs when the load condition changes
as follows:
1.4.1 Constant Voltage (CV), Automatic Crossover &
Constant Current (CC)
The power supply functions as a constant voltage source (CV) as
long as the load current is less than the preset current limiting value.
When the load current is equal to or greater than the preset current
limiting value, the power supply will automatically cross over to the
constant current mode, voltage will drop, (CC) will show on the LCD
display panel and it will operate as a constant current source.
When the load current drops below the preset current limiting value,

the supply returns to constant voltage (CV) mode.
1.4.2 Set the Output Voltage and Presetting Current
Limiting Value (CC)
Turning the voltage or current knob to set your desired values.
Quick pushes on the knobs will move the decimal place for fast
tuning.

otherwise you need to repeat quick pushes again.

setting indicator (15) is On.
1.6 Connecting outputs in series

with the 12 V outputs.
The 2 outputs (Aux.1) can be connected in series to make a
variable 5 V to 41 V with maximum current 2 A (Figure 3).
The 3 outputs can be connected in series to make a variable 17 V
to 53 V with maximum current 1 A, (Figure 4).
There are other combination of cross connections for different
positive and negative output voltages.

1.7 Tracking Output Over Voltage Protection (OVP)
This is to protect the connected load in the event that the output
voltage control circuit malfunctions, the maximum output voltage
will not exceed 30% of the adjusted voltage value at the time of the
operation.
1.8 Over Temperature Protection
When the temperature inside the power supply becomes higher
than a pre-determined value, the output voltage and current of the
power supply will automatically decrease to zero to prevent damage
to power supply. When the temperature inside the power supply
returns to normal then the power supply will automatically return to
operation again.
