Which of the following will help protect against brown outs?

A power supply converts AC to DC but cannot compensate for insufficient incoming AC voltage during a brownout.

An anti-static strap protects against electrostatic discharge (ESD) and has no relation to power quality issues.

A surge suppressor protects against overvoltage spikes, not undervoltage brownout conditions.

A UPS (Uninterruptible Power Supply) with battery backup provides line conditioning and can compensate for brownouts - sustained undervoltage conditions - by switching to battery power to deliver stable voltage to connected devices. It actively monitors incoming power quality and responds to both outages and voltage sags. Surge suppressors only protect against overvoltage, and power supplies alone cannot compensate for insufficient incoming voltage.
