Clean Power

This is the ideal mode for all electrical equipment.

Surges

Power surges can result in permanent damage to hardware and other electrical equipment.

Suggested solution: powerline conditioner or UPS with voltage regulation.

Sags / Brownouts

These are short term, low voltage brownouts, created by large loads, lightning, utility switching or equipment failure. Sags/brownouts cause hardware crashes and occasional hardware damage.

Suggested solution: powerline conditioner or UPS with under and over voltage protection.

Spikes

Also called transients or instantaneous surges. Spikes cause data corruption, data lockups and significant hardware damage.

Suggested solution: UPS with surge suppressor, mains spike or filter.

RF Noise

Creates a rough and jagged sinewave. RF noise can even be generated by normal computer operation. It causes keyboard lockups, program freezes and data corruption.

Suggested solution: UPS and noise filter or RF mains filter.

Waveform Distortion

Most common is the harmonic distortion, which causes a doubling of the normal sinewave. This condition can be triggered by factory equipment or utility power.

Suggested solution: true on-line double conversion UPS.

Frequency Vibrations

Mainly caused by back up generators taking over from utility power. Only on-line UPS systems can rectify this problem.

Suggested solution: true on-line double conversion UPS.

Complete Outage / Blackout

Described as 0 volts condition for longer than half a cycle. Unprotected networks suffer badly during an outage.

Suggested solution: true on-line double conversion UPS.
