Zero Surge has once again revolutionized surge protection by developing and patenting Spectrum WVR™ Wide Voltage Range technology. Using a dynamic clamp surge inversion system, Spectrum WVR™ effectively functions from 85 Volts all the way up to 175 Volts and anywhere in between. Spectrum WVR™ is ideal for applications where:

• sensitive electronic equipment is used.
• voltage is variable and unpredictable.
• brownout or blackout conditions occur.

Enhanced Spectrum WVR™ is also available which expands the wide voltage range from 85-265 Volts. It is ideal for international use and where versatility is needed (one unit functions in both 120, 208 and 240V applications).

Surge protectors using "fixed clamping level" components such as metal oxide varistors (MOVs) perform much worse under brownout and blackout conditions since they do not even begin to function until their clamping level is exceeded. Series Mode technology together with Spectrum WVR™ eliminates this problem with a dynamic response to surge voltage. There is no surge protection product in existence with a lower clamping level. Zero Surge’s Spectrum WVR™ technology is the ultimate surge protection technology available today.
