Constant Voltage Output
DP800A series power supply provides three output modes: constant voltage output
(CV), constant current output (CC) and critical mode (UR). In CV mode, the output
voltage equals the voltage setting value and the output current is determined by the
load; in CC mode, the output current equals the current setting value and the output
voltage is determined by the load; UR is the critical mode between CV and CC. This
section introduces the operation method in constant voltage output mode.
Operation Method:
1. Turn on the power switch to start the instrument.
2. Select the channel
Select the proper output channel according to the desired output voltage. Press
the corresponding channel selection key; at this point, this channel, its channel
number and output state are high-lighted on the screen.
3. Set the voltage
Method 1
Press Voltage and use the left/right direction keys to move the cursor; then,
rotate the knob to set the voltage and the default unit is V.
Method 2
Press Voltage, use the numeric keyboard to input the desired voltage and press
V or mV or press the unit selection key or to select the desired
unit. Besides, you can also press OK to select the default unit V. During the
input, press Back to delete the character currently before the cursor and press

4. Set the current
Method 1
Press Current and use the left/right direction keys to move the cursor; then,
rotate the knob to set the current and the default unit is A.
Method 2
Press Current, use the numeric keyboard to input the desired current and press
A or mA or press the unit selection key or to select the desired unit.
Besides, you can also press OK to select the default unit A. During the input,
press Back to delete the character currently before the cursor and press
Cancel to cancel the input.
5. Set the overcurrent protection
Press OCP to set the proper overcurrent protection value. For the setting
