Why each option
A surge suppressor is designed specifically to clamp or absorb excess voltage from power spikes and surges, protecting connected equipment from damage.
Electrostatic discharge protection requires grounding straps, anti-static mats, or ESD-safe bags - not a surge suppressor connected to AC power.
Power blackouts require a UPS (Uninterruptible Power Supply) with battery backup to maintain power during outages.
Surge suppressors use Metal Oxide Varistors (MOVs) or similar components that absorb energy when voltage exceeds a set threshold, diverting the excess away from connected devices. This directly protects against sudden power spikes or surges. The device has no mechanism to supply power during outages or regulate under-voltage conditions.
Power brownouts are under-voltage conditions that require a line-interactive UPS or automatic voltage regulator (AVR) to correct.
