Over Current Protection (OCP)
The OCP alarm is a firmware alarm that is only configurable using the
SCPI interface. The OCP triggers if the output current exceeds the OCP
set point. Because the OCP alarm is a firmware based alarm it has a
latency before detection of the condition can occur. The user should be
aware of this latency and take this into consideration when relying on
OCP to protect a sensitive load. The maximum period for detecting an
OCP condition is 300 ms.
OCP is fixed at 110% of rated current.
