Connecting a 25
Ω
resistive load
We consider a case of using a load resistance of 25 Ω . In this case,
when the output current limit is set to 4 A or more, the power supply
is capable of outputting voltages from 0 V to the rated maximum out-
put voltage while in constant voltage operation mode. In this load
condition, the output voltage limit is the rated maximum output volt-
age (for these conditions) and the output current is gradually
increased from 0 A. At this time, the power supply is operating in the
constant current (CC) operation mode. The power supply increases
the output voltage in order to source the current setting. When the
output voltage reaches the supply's maximum rated output of 100 V,
no more current can be sourced to this load, regardless of the current
setting.
If you wish to increase the current
fl ow further in this condition, the
unit needs to be replaced by a model having higher output voltage.
Particularly for loads where a transient surge voltage is generated, the
voltage must be set so that the surge voltage does not reach (or
exceed) the voltage limit.
