Uninterruptible Power Supply (UPS)

The UPS typically combines surge suppression with batteries. The surge suppressor portion protects against over voltage conditions along with EMI and RFI.

Under voltage conditions or no power, then the power is either boosted or replaced from the batteries. Unfortunately, batteries do not last forever. Most UPS system are designed to keep a PC running, and do not have the ability to keep a device with heavy power demands running.

Laser Warning

Do not plug a laser printer into an UPS.
