Load
Note that the output may become unstable when one of the following loads is
connected.
2.3.1
When load current has peaks or is pulse-shaped
The current meter on the power supply indicates only mean values. Even when the
indicated value is less than the preset current value, therefore, a peak may exceed the
preset current value. In such a case, the power supply is instantaneously put into
constant-current operation mode, and the output voltage drops accordingly. If you
look carefully, you will see the constant current (CC) indicator light up dimly.
For such a load, a larger value should be preset for the constant current, or the current
capacity should be increased.
