ELS-304
Operations of Load Modes 5-7
5.7 Constant Volt. (CV) Mode
For power supplies having internal resistor, the Load current
will change so that the Load Volt. This mode is optimal for
rechargeable batteries Testing.
(1) Press the “rotary knob” to set mode select condition. and then turn the knob until “CV” is
displayed as shown below.
(2) Input setting value by “ten keys”, and then press “ENT” key to confirm the setting value.
(3) Press “ON/OFF” key to select ON to start flowing the load current to keep the setup volt.
Fig.5-7-1 Operation in CV mode
・
Due to the principle of CV mode Operation, you may find oscillation and
unstable load control because of wiring conditions. In such cases, you may
stabilize the load control by changing the loop gain value to stabilize the
measurement. For changing the loop gain, refer to
→
”
5.3 Response Time
”.
・
When Load is set ON, over power alarm is also ON due to the inrush current. In
such a case, you may avoid it by changing the curr. Limit value. For changing the
it, refer to
→
”
5.4 Curr. Limit Setting
”. However, the curr. limit value should
not cause any trouble for normal operation and also should avoid the situation
that the value multiply volt value in no load condition by the setup curr. limit
value exceeds the rated power (300W).
・
In CV mode. there is no AUTO range for the load setting. Please note that the
max load current should be the max value of the range selected.
