CC Load Regulation Rate (CC Load Effect)
CC load regulation rate refers to the relation between the variation of the output
current (caused by the load effect) and the rated output current when the power
supply is under CC output mode.
DP831A is taken as an example to test the CC 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)
Current <0.01%+250μA
Test Procedures:
1. Turn off DP800. Connect DP800, AC power supply, current sampling resistor (the
resistance R
M
is 0.022Ω), electronic load and multimeter according to Figure 3-1.
Please pay attention to the connection method of the current sampling resistor,
electronic load and the channel output terminals of DP800 as well as the
connection method of the current sampling resistor and multimeter. 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 3-1
. 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. Set the electronic load to short circuit mode. At this
point, the channel under test of the power supply is in CC mode.
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 CC mode. Read and
record the reading (U
0
, namely the voltage of the current sampling resistor) of
the multimeter.
