Don't Forget The UPS Device Or Surge Protector!

Written By:  Jeff H. Reynolds

One thing that most everyone forgets about is the purchase of a UPS device or Surge Protector.  When we mention this concern to our customers... assuming that they know what one is... it seems that most believe that a $5 device from the local drug store is sufficient to protect their equipment and investment.  They couldn't be more wrong.  

Are you wondering what a surge protector does?  In simple terms... in the United States, the common household voltage is 120 volts.  Unfortunately, that voltage isn't always constant or stable.  It fluctuates.  And, in some instances, it may reach levels that can be damaging to your electronics and other devices.

When the voltage level rises for a period of three nanoseconds or more, the event is referred to as a surge.  When the voltage level rises for a period of less then two nanoseconds, the event is known as a spike. 

If the surge or spike is high enough... substantial damage can occur.  Think of it like this... if you put too much pressure on a water hose what happens?  It bursts.  In the instance of electronics, too much voltage will result in the heating up of the wires/components... burning them up.  Damage doesn't always show itself immediately.  Sometimes, it's a cumulative thing... showing up later... hours, days, weeks later.

Surges and spikes can be caused by something as simple as your airconditioner turning on... or the refrigerator cycling.  There a number of possible causes including lightning strikes and transformer issues.

We recommend that you purchase a device with a Clamping Voltage of no more than 330 volts. 

We also recommend that you purchase a device with an Energy Absorption/Dissipation rating of at least 600 joules.

And, you want a Response Time of no more than one nanosecond.

A UPS (uninterruptible power supply) is the best choice as it will keep your devices operational even when there is a power outage.  This gives you a chance for an orderly shut down of your equipment.  UPS units generally combine surge protection with a continuous uninterruptible power supply.    The basic design of a continuous UPS is to convert AC power to DC power and store the power/energy on a battery.  The UPS then converts the battery's power from DC back to AC and runs it to the outlets for your electronics. 

UPS units typically range in price from $50 to $500 or more.  A basic surge protector will run anywhere from $5 to $50 generally.  This is one instance where you typically get what you pay for.  Be sure to by a name brand device with a warranty.  APC is a leader.  I recommend them.
