Power protection for computers: Which option is specifically designed to clamp transient overvoltages and help prevent power surges from damaging equipment?

Introduction / Context:
Electrical surges and spikes can damage power supplies, storage, and logic boards. Different devices protect against different power problems; selecting the right one minimizes downtime and data loss.

Given Data / Assumptions:

• Concern is transient overvoltage (surges/spikes) on AC mains.
• Consumer/professional protective devices include surge suppressors and UPS units.
• Measurement tools (multimeters) do not provide protection.

Concept / Approach:

A surge suppressor (surge protector) uses components like MOVs (metal-oxide varistors) or TVS diodes to clamp high-voltage transients, diverting surge energy away from loads. It is the primary device for surge protection. UPS units may include surge suppression, but their core purpose is ride-through power during outages and brownouts.

Step-by-Step Solution:

Verification / Alternative check:

Spec sheets list joule rating and let-through voltage for surge strips. Higher joule ratings imply greater energy absorption. A UPS specification emphasizes VA/W capacity and battery runtime; surge ratings are secondary.

Why Other Options Are Wrong:

• Spike protector: Not a standard product term; if meant as a generic, it is redundant with surge suppressor. The precise term is surge suppressor.
• UPS system: Provides backup and regulation; not primarily a surge protective device.
• High-grade multi-meter: Measurement only; offers no protection.
• None of the above: Incorrect because surge suppressors directly address surges.

Common Pitfalls:

Confusing power conditioning with surge suppression; ignoring proper grounding; overloading multi-outlet strips beyond their rating.

Final Answer:

Surge suppressor
