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. Connect the channel output terminals

As shown in the figure below, connect the load to the output terminals of the

corresponding channel at the front panel.

CAUTION

To avoid damaging the instrument or the device connected to it, pay

attention to the polarity when connecting.

2. Turn on the power switch to start the instrument.

3. 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.

4. Set the voltage

Method 1

Press Voltage and use the left/right direction key to move the cursor; then,

rotate the knob to quickly set the voltage and the default unit is V. After selecting

the digit to be set, you can also use the up/down direction key to modify the

value of the corresponding digit and the default unit is V.

Method 2

Press Voltage and use the numeric keyboard to directly input the desired

voltage value; press V or mV or the unit selection key ( or ) to select

the desired unit. Besides, you can also press OK to select the default unit (V).
