1. This does not protect against the discharge current peak that is generated from the capacitors inside the PWR-01
output section when the load is changed suddenly.
2. Available on models with a maximum settable current of 11 A or more. If the OCP value is less than the FOCP
value, the OCP value takes precedence.
3. Auto recovery after eliminating the cause of the alarm is selectable.
