Operating Basis
Connection of Load Line
1. Rotate terminal counterclockwise
to loosen the terminal
2. Insert load line terminal
3. Rotate terminal clockwise to lock the terminal
4. Banana plug: insert the banana plug into terminal block
Type of load line: The load line is an optional accessory for users, and current
capacity of load line must be confirmed when the load line is purchased. The voltage
drop at both ends of each load line cannot exceed 0.5V. The following table shows
rated current of the load line.
Characteristics of Constant Voltage/Constant Current
1. The DC power supply can automatically switch between
constant voltage mode (C.V.) and constant current mode
(C.C.) according to load conditions. When output current
is less than output preset value, the DC power supply
works in constant voltage mode, andfront panel indicator
lights green (C.V.). The output voltage is constant at the
set value; when output current changes with the load and
the current reaches the preset value, the power supply
enters a constant voltage mode (C.C). Indicator on the
front panel is red (C.C.)The current output will be constant
at the preset value, and output voltage will vary with the load. When the output current
is less than the preset value, DC power supply will automatically return to constant
voltage mode (C.V.)
Note 1: Incorrect connection may cause damage to power supply or the load connected
to DC power supply.
2. In actual (C.V.) operation, if output current increases to the setting value due to
decrease of load resistance, the power supply will automatically switch to (C.C.) mode.
When load resistance continues to decrease, the current will remain at the setting
value. The voltage will decrease proportionally (I=V/R). At this time, C.V. output state
can be restored by increasing load resistance or improving setting value of current.
3. In actual (C.C.) operation, if output voltage increases to the setting value due to
increase of load resistance, the power supply will automatically switch to (C.V.) mode.
When load resistance continues to increase, the voltage will remain at the setting
value. The current will decrease proportionally (I=V/R). At this time, C.C. state can be
restored by reducing load resistance or increasing setting value of voltage.
