4.1 Maximum Output Current and Operation Range
This product has a protection circuit that detects an output current and internal loss to limit the output
current. A maximum output current is determined by this protection circuit. This limitation value varies,
depending on the output time and output voltage. The relationships are shown in "
Figure 4-1
Operation Range
".
Each graph shows an AC (40 Hz) peak value range and a DC range.
In general, if the load is resistive for an AC signal, quadrants I and III cover an operation range. If the load
is capacitive or inductive, all four quadrants cover an operation range.
If the load involves an electromotive force with a DC signal, and an operation is performed to supply
current from the load, quadrants II and IV cover an operation range.
For square wave input, when waveform rise/fall is fast, even if a lower frequency (period) is used, the
output current protection range may be reached by a charge current for output cable capacitance or stray
capacitance inside this product, resulting in overload even if no load. In this case, decrease output voltage
or slow the waveform rise/fall by using a signal generator (e.g., WF1947) that is capable of controlling
waveform rise/fall.
