Combination for Performing Charge/Discharge Tests
Selecting the appropriate DC power supplies and electronic
loads
The range is different between charging and discharging. Select DC power supplies and electronic
loads that meet each condition.
The graph below shows the range of chargeable voltage and current using the following equation.
Use devices whose voltage (constant voltage, cutoff voltage) and current (constant current) do not
exceed the range.
Maximum charge power = Maximum rated power of DC power supply – Loss in cables

What is loss in cables?
Voltage drops occur as a result of charge currents flowing through DUT cables, connection
cables, PFX2532 current path circuits, and so on. Loss in cables is the power loss during
charging due to this voltage drop. The maximum power that can be used for charging is the
resultant value after subtracting the loss in cables.
If the allowable power of DC power supplies is exceeded during charging, PS / B alarm or the like
occurs, and the test is aborted.
