Connecting the Load
This chapter describes the consideration to be given to the load,
explains how to connect the load wires, and explains how to
connect to the output terminal.
3.1
Load Considerations
Note that the output will become unstable if the following types
of loads are connected.
•
When the load current has peaks or is pulse-shaped
•
When the load generates a reverse current to the power
supply
•
When the load has accumulated energy such as batteries
3.1.1
When the Load Current Has Peaks or is Pulse-
shaped
The current meter on the PMC-A indicates only mean values.
Even when the indicated value is less than the preset current
value, the peak values may actually exceed the preset current
value. In such cases, the PMC-A is instantaneously put into
constant-current operation mode, and the output voltage drops
accordingly.
For these types of loads, you must increase the preset current
value or increase the current capacity.
