1 Undervoltage sensors causes each channel to switch off and reset.

2 Overvoltage sensors causes each output channel to switch off to protect its load.

3 Above this temperature measurement of these parameters is prevented because OT protection may occur prior to SC protection.

4 SC protection for P

 is latched.  Normal operation may only be resumed after the input is toggled low then high again.

Normal operation is maintained as long as P
