CV Load Regulation Rate (CV Load Effect)
CV load regulation rate refers to the relation between the variation of the output
voltage (caused by the load effect) and the rated output voltage when the power
supply is under CV output mode.
DP831A is taken as an example to test the CV load regulation rate of DP800 series in
the following section.
Note: During the actual test, please select the corresponding test record form
according to the model of the DP800 power supply under test to set the
corresponding parameters, record and calculate the corresponding specifications.
Specification:
Load Regulation Rate, ± (Output Percentage+Offset)
Voltage <0.01%+2mV
Test Procedures:
1. Turn off DP800. Connect DP800, AC power supply, electronic load and
multimeter according to Figure 2-1. Both the electronic load and multimeter are
connected with the channel output terminals of DP800; please refer to “Test
Precautions” for the connection method. Here, CH1 is taken as an example
and the connection method is also applicable to CH2 and CH3.
2. Turn on the AC power supply; set its voltage to 230V and frequency to 50Hz.
Note: The voltage setting of the AC power supply in this step should be in
accordance with the value selected by the voltage selector at the rear panel of
DP800.
3. Turn on DP800 and press the channel selecting key at the front panel to select
CH1 as the channel to be tested. Set the voltage and current of the channel
under test according to Table 2-1
. Then, press the On/Off key corresponding to
the channel under test to enable the output of the channel.
4. Turn on the electronic load. Adjust the current of the electronic load to 0A or do
not connect any load device (no load).
5. Turn on the digital multimeter; select DC voltage measurement function and set
the range to “Auto”. Make sure that the power supply is in CV mode. Read and
record the reading (U
0
) of the multimeter.
6. Set the electronic load to work in CC mode and adjust the current of the
electronic load to the rated output current (please refer to Table 1-1) of the
