BRIEF PRODUCT INTRODUCTION
APS-730X series single-channel programmable power supplies are
designed to supply wireless devices with stabilized voltage or
current, while used in debugging processes, repair and laboratory
research in normal climate conditions.
Power Supply APS-7306 is a highly accurate, DC-regulated power
supply with an adjustable output. This output can be used for
constant voltage (C.V.) and constant current (C.C.).
The output voltage can be adjusted between 0V and 30V when
the device is in the constant voltage mode. The current-limiting
point can be set arbitrarily in this mode.
The output current can be adjusted continuously between 0A and
5A in the constant current mode. The output current and voltage
are indicated on the LED displays
INSTRUCTIONS
•Never put the heavy objects on this equipment;
•Never crash or damage the machine due to improper
operation;
•Never make the equipment be static discharge;
•Don't block the cooling exit;
•Don't make the equipment power on when it is connected to
the power;
•Never disassemble it unless getting the confirmation of the
professionals.
WARNING
•Output voltage 110V 60Hz
•The power cord must be with reliable grounding to avoid the

OPERATION
Switching the Power Supply On or Off
1. Connect the included power cord to the back of the device [16] and
plug the other end into a suitable, earthed power socket.
Always connect the device to an earthed power socket.
2. Press the Power button [1] to switch the power supply on.
At this moment, there is no output voltage or current on the output
terminals.
3. Press the Power button [1] to switch the power supply off.
Using the Power Supply in Constant Voltage Mode
If you want to use the power supply in constant voltage mode, you set up the
desired output voltage between 0V and 30V. You also set up the desired
current limit.
If the output current exceeds the limit, the power supply automatically goes
into constant current mode.
Using the Power Supply in Constant Current Mode
If you want to use the power supply in constant current mode: you set up the
desired output current between 0A and 3A/5A. You also set up the desired
voltage limit.
Setting Voltage and Current
You can save 3 different voltage/current settings using the memory keys
M1~M3.
1. Press the Voltage/Current key [5] to set the voltage. The voltage readout
flashes.
oFor use in constant voltage mode: this is the desired constant
voltage.
2. Turn the adjustment knob [11]until you reach approximately the
desired voltage. Press [11] to select a digit in the voltage readout [9] and
turn the adjustment knob to fine-tune.
3. Press the Voltage/Current key [5] again to set the current. The
current readout flashes.

oFor use in constant voltage mode: this is the desired current
limit.
oFor use in constant current mode: this is the desired constant
current.
oIf you enable overcurrent protection, the output switches
off automatically if the current exceeds this value.
4. Turn the adjustment knob [11] until you reach approximately the
desired current. Press [11] to select a digit in the current readout [10]
and turn the adjustment knob to fine-tune.
5. Press the memory key [3] again (or wait until the display to start
flashing). Then press the m1-m3 button The settings are saved in the
selected memory.( the display stops flashing)
Recalling Settings
To recall one of the saved settings, press the corresponding memory key
M1~M3 [4]. the corresponding voltage/current settings appear on the
display.
Note: the output is switched off automatically when you press a
memory key to recall a setup.
Using Memory 3
To use memory 3, proceed as follows:
1. Set the voltage and current as desired Press memory key [3],Wait
until the display start to flashing. Then Press key [4] the settings are
automatically stored in memory, and until the display stops to flashing.
2. To recall the settings, press key 4.
Connecting a Load
1. Connect the load’s positive terminal to the red + terminal [14] of the
power supply.
2. Connect the load’s negative terminal to the black – terminal [12]
of the power supply.
3. You can connect the + or –terminal to the green earth terminal
[13] of the power supply to pin the voltage to 0V (earth potential)
at that terminal.
If you leave the earth terminal unconnected, the output floats with
respect to the ground.

Applying Voltage to the Load
1. Press the Off/On key [1] to apply the voltage to the load.
The OUT [2] and C.V. indicators [8] light. The power supply
works in constant voltage (CV) mode; the display now shows the
actual output voltage and current.
If the current exceeds the set current limit, the power supply
automatically goes into constant current (CC) mode. The C.V.
indicator goes out and the C.C. indicator [7] lights.
2. Press the Off/On key [1] to switch the output off.
PROTECTION
Using Overcurrent Protection
1. To protect against overcurrent, set up the maximum current and
then press the OCP button.
2. Press Off/On to apply the output to the load.
If the output current becomes higher than the set value, the
power supply cuts off the output and the OCP indicator flashes.
3. Disconnect the load. To recover, press the OCP key.
