Over/Under-Voltage Shutdown
Over-/Under-Voltage Shutdown indicates whether a power device disconnects its outputs when the incoming mains voltage falls outside specified limits.
The function responds to excessive or insufficient voltage rather than maintaining a corrected output continuously. It is distinct from voltage regulation and from protection against very brief surge events.

Check the shutdown thresholds, response conditions and how power is restored. Some designs reconnect automatically after a delay; others require action. The feature label alone does not establish those behaviours or guarantee uninterrupted operation.
Connected equipment should be suitable for the resulting power interruptions and restart sequence. A shutdown does not identify the underlying cause of a supply problem. Follow the product’s instructions if it repeatedly disconnects, and do not bypass protection or alter mains wiring to keep the system running.
