Selecting the system for the DC power supplies and the electronic loads
The range is different between the charge operation and the discharge operation state. Select the
applicable model of the DC power supply and the Electronic load that meets each requirement.
The following graph indicates the range of allowable charge voltage value / current value
calculated by the formula specified below. Use the equipments which do not exceed the range of
the voltage value (constant voltage value/end voltage value) and the current value (constant
current value).
Maximum charging power = Maximum rated power of the DC power supply

Route loss
*1
*1. What is the route loss?
The voltage drop is occurred in the DUT cable, the connecting cable, and the PFX2512 current
passing circuit, etc. caused by flowing the charging current. The route loss is the power loss of the
voltage drop while the execution of charging state. The allowable maximum power in the charging
state is the value subtracting the route loss.
When the charging power exceeds the range of allowable power of the power supply while the
charge operation is executed, the PS / B alarm will be activated and stop the testing.
