OPERATION INSTRUCTIONS
Bedieningsinstructies
There are two types of power output modes: constant voltage output (CV) and constant
current output (CC). The output mode is determined by the voltage and current values set
by the user and the load connected by the user.
The output voltage or current value of the power supply won’t exceed the voltage and
current values set by the user.
In constant voltage mode, the output voltage value is equal to the user-set voltage. In
contstant current mode, the output current value is equal to the user-set current.
For example: the voltage value is set to 5V and the current value is set to 5A.
1.
Turn on the power button.
2.
Adjust the voltage adjustment knob to 5V.
3.
Short-circuit the “positive” and “negative” terminals with test leads and adjust the current knob to 5A.
4.
Disconnect the test leads and connect the load.
CONNECT THE LOAD USING NON-4MM (BANANA) LEADS
1. Rotate the terminal knob by turning it counterclockwise.
2. Insert the load terminal.
3. Turn the terminal knob clockwise.
CONNECT THE LOAD USING 4MM (BANANA) LEADS
1. Insert it directly into the terminal.

In actual CV operation, if the load resistance decreases and the output current increases to the set current
value, the power supply will automatically switch to CC mode. When the load resistance value continues to
decrease, the current will remain at the current set value. The voltage is proportionally reduced. At this time,
increase the load resistance or increase the current set value to restore the CV output state.
An incorrect connection can damage the power supply and/or the load connected to
the power supply. When connecting a battery / accumulator, make sure not to swap the polarity of the “+”
and “-” as this may cause damage to the power supply. In addition, before connecting, make sure that the lab
power supply is set to a higher voltage than the battery / accumulator so that no current can ever flow from
the battery back to the power supply.
