BROWNOUT ALERT!

FRENCHTOWN, NJ – July 17, 2002 – Virtually all methods of surge protection lose their effectiveness when brownouts occur. Computers are especially susceptible to surge damage during brownout conditions as most of the powerline surge suppressors and UPSs connected to them use fixed clamping level MOVs. This clamping level must be set higher than the highest anticipated powerline voltage or thermal runaway (overheating) will occur due to the MOV conducting on the power wave peak voltage. This could also lead to catastrophic failure and fire.

During a brownout, no protection is afforded until the surge exceeds the MOV clamp level which is much higher than the power wave during the brownout. The result is that the computer’s power supply sees a much larger surge before any suppression takes place, greatly increasing surge exposure. Zero Surge has recognized and eliminated this problem by introducing a dynamic new technology. This breakthrough technology is called series mode with Spectrum WVR® (wide voltage range).

Unlike a fixed clamping level device, Spectrum WVR® features a dynamic clamp or instantaneous response to surge current and voltage. With brownouts occurring more frequently, don’t leave your important equipment exposed to danger -- plug in to Spectrum WVR® for assured protection.
