UNDERVOLTAGE & OVERVOLTAGE CHARACTERISTICS
Limits are at -40˚C ≤ T
OVERLOAD PROTECTION CHARACTERISTICS
Independent protection per channel. Refer to
5.5 V ≤ V
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
5 Trip time t
6 After cooling below the reset temperature the channel will resume normal operation.
