1
New cards

Brownout

A temporary drop in voltage.

2
New cards

Surge

A temporary excess of voltage.

3
New cards

UPS (Uninterruptible Power Supply)

Battery-backed device providing short-term power during an outage; bridges gaps measured in minutes, not days.

4
New cards

Offline/standby UPS

Runs on main power normally; switches to battery only when main power fails. Lower-end, cheapest, has a brief switchover delay.

5
New cards

Line-interactive UPS

Can compensate for voltage drops by boosting voltage without fully switching to battery. Good for areas with frequent brownouts.

6
New cards

Online/double-conversion UPS

Always runs from battery continuously; main power just keeps the battery charged. Zero switchover time.

7
New cards

Graceful shutdown (UPS feature)

UPS signals connected systems to shut down properly before battery is fully depleted, avoiding corruption from an abrupt power loss.

8
New cards

Generator

Long-term power backup, running as long as fuel is available; can cover an entire building or specific generator-power circuits.

9
New cards

UPS + generator combo

Standard pairing: UPS covers the brief gap while a generator starts up (about a minute), then load transfers to the generator for sustained outages.
