The traditional surge protector on the right can cause a lot of harm endangering your electronic equipment, possibly setting a fire to your home or business. MOV's wear out with use. You can buy it for a few dollars and take the risk.
POINT OF USE, TRADITIONAL SURGE PROTECTORS, SHUNT THE SURGE TO GROUND AT THE COMPUTER, WHERE IT LEAPS ACROSS SERIAL PORTS,NETWORK CONNECTIONS, ETC. DOING ITS DEADLY WORK.
Interconnected (networked) systems share common power and data lines form circuits between themselves via the ground wire (both referenced at the load). A power line surge diverted to the ground wire will make its way to the chassis, through the motherboard onto and through the data lines because the power line ground is used as a voltage reference and therefore is also connected at the motherboard and to the data ports of the rest of the connected system. This is where most data line surges originate.
Are you using a UPS Unit?
It is our contention that you should have a series mode surge protector, such as a Zero Surge unit, in front of your UPS unit? This is so that the MOV in the UPS unit won’t pollute the equipment ground and so the MOV won’t dump a lightning strike or other destructive spike onto the equipment ground where it can blow up other equipment whose signal wiring may be connected to the equipment ground.
Problems when you are using standby generators and your MOV type suppressors:
Standby generators used in critical applications can experience brief voltage overshoot during start up, load changes, and with contaminated fuel. Voltage overshoot will stress fixed clamping level (MOV Type) suppressors, leading to premature and unpredictable failure.
Zero Surge filters use Spectrum Wide Voltage Range Technology effectively functions from 85 volts all the way to 265 volts and anywhere in between.
