1 Undervoltage sensor causes the device to switch off and reset. 2 Overvoltage sensor causes the device to switch off to protect its load. 3 The status will continue to indicate OT (even if the input goes low) until the device cools below the reset threshold. Refer to... -
Page 6: Overload Protection Characteristics
After short circuit protection has operated, the input voltage must be toggled low for the switch to resume normal operation. 2 Measured from when the input goes high. 3 After cooling below the reset temperature the switch will resume normal operation.
