Constant Voltage Output

DP800 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 with the channel output

terminals of the corresponding channel at the front panel.

CAUTION

Pay attention to the polarity when connecting them to avoid damaging

the instrument and the devices connected to the instrument.

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, output state and output mode 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. The default unit is V.

Method 2

Press Voltage, use the numeric keyboard to directly input the desired voltage

value and press V or mV or press the unit selection key ( or ) to
