Why each option

To protect equipment from under-voltage events like sags or brownouts during peak periods, an Uninterruptible Power Supply (UPS) is the most effective solution.

AProper ventilation

Proper ventilation manages heat dissipation and does not protect against electrical power fluctuations like under-voltage.

BUPSCorrect

A UPS provides voltage regulation and battery backup, making it ideal for protecting equipment from under-voltage events. It can detect when incoming voltage drops below a safe threshold and either boost the voltage to an acceptable level or switch to battery power, preventing system shutdowns and potential hardware damage.

CSurge protector

A surge protector is designed to safeguard against sudden spikes of over-voltage, not against drops in voltage.

DPDU

A Power Distribution Unit (PDU) distributes electrical power to devices but typically does not offer voltage regulation or battery backup capabilities.
