4.4 Setting of limiters
To protect the load, the BP4620 has output voltage and output current limiter functions implemented
through hardware.
The maximum values for the output voltage and output current can each be set independently for the
negative and positive range. Limiting the output voltage and current to the set values is effective for
preventing failure of the connected load.
Limiter setting values are separately stored in the CV and CC modes.
For details on the output voltage and output current supply ranges,
refer to “8.18 Output Voltage
and Output Current Supply Ranges”
.


Output voltage range
The output voltage range of the BP4620 is determined by the

voltage limiter settings.
The maximum and minimum ranges of the

voltage limiter are limited to 124 V and 24 V,
respectively, and are reciprocally linked.

Saving of output voltage/output current setting values
Limiter setting values are separately stored in the CV and CC modes.

Output voltage/output current setting resolution
The actual setting resolution is approximately 0.12 V and 0.06 A.
During output of a high frequency (higher than approx. 1 kHz in the case of a sine wave), note that the
output may exceed the limiter level due to limiter operation delay.
