*1. Output off or breaker trip on the 2000 W model. *2. 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. *3. 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. *4. Auto recovery after eliminating the cause of the alarm is selectable.
