To Use the Power Supply in Constant Current Mode
To set up the power supply for constant current (CC) operation, proceed as
follows.
For each step, use the keys shown on the left margin.
1
Connect a load to the output terminals.
With power-off, connect a load to the (+) and (-) output terminals.
2
Turn on the power supply.
The power supply will go into the power-on / reset state; the output is disabled
(the
OFF annunciator turns on); the 15V/7A range is selected (the 15V
annunciator turns on); and the knob is selected for voltage control.
To operate the power supply in the 30V4A range, press key before
proceeding to the next step. The
30V annunciator turns on.
3
Set the display for the limit mode.
Notice that the
Limit annunciator blinks, indicating that the display is in the
limit mode. When the display is in the limit mode, you can see the voltage and
current limit values of the selected supply.
4
Adjust the knob for the desired voltage limit.
1
Check that the Limit annunciator still blinks and the second digit of voltmeter
blinks to indicate the knob is selected for voltage control. The blinking digit
can be changed using the reolution keys and the blinking digit can be adjusted
by turning the knob. Adjust the knob for the desired voltage limit.
1
You can use the resolution selection keys to move the blinking digit to the right or
left when setting the voltage.
In constant current mode, the current values between meter mode and
limit mode are the same, but the voltage values are not. Moreover if the
display is in the meter mode, you cannot see the change of voltage limit
value when adjusting the knob. We recommend that you should set the
display to "limit" mode to see the change of voltage limit value in
constant current mode whenever adjusting the knob.
