APPLICATION NOTES 

Equipment damage is the most serious and noticeable effect of spikes & surges. Damage may range from moderate to severe. Immediate consequences depend on value of equipment damaged and the value placed upon that equipment being in continuous service.

Spikes & surges (especially from Lightning) may enter equipment over Power, Phone, Control or Monitor lines at the same time. From there, spikes / surges often inductively couple into network data and control lines.

Damage to network cards often results, but unnoticed is the long term performance deterioration spikes & surges cause in network equipment. Each time severe spikes or surges enter equipment, some delicate components may suffer slight degradation. Over time, this cumulative degradation takes its toll, leaving equipment performing in a sub-standard manner - eventually leading to erratic performance or system failure.

In some instances, spikes & surges may find their way past the network cards, into critical operating circuitry. Computer digital circuits may receive false data, causing errors and disruptions. Again, cumulative performance degradation may result.

What to Do ?

Installation of High Performance Spike/Surge protection equipment is the best defensive action to prevent equipment damage, data loss or system down time.

Network and Data information is connected to electronic equipment through a number of different style connectors. Additionally, various systems use different pins of the same connector. Also, different voltages are encountered in different applications.

When selecting Protection systems for installed Network, Data, Security or Signal equipment, consult the manufacturer to ascertain correct connector, correct pins and correct protection voltage.

There are some "universal" protection devices on the market. While in theory, this sounds great, usually the protection voltage level chosen is quite high so that all equipment can be connected without affecting the data or signal. Net effect is that a 3 or 5 Volt system may be protected with a 30 or 40 Volt Protector, leaving equipment exposed to undesirably high residual Spike Voltages. Premature equipment failure or erratic data / signal transmission could result.

ENTRANCE PROTECTION:

Often DataLine, Network or Controller cables are interconnected between buildings.
We have designed Entrance Protection systems for many installers.
Consult us for hi-performance solutions for your entrance requirements.
Note that .... RS-232, RS-422, RS-485, RS-530,
or any other data or network configuration, can be supplied with flanged mounting
and any required connectors to protect signal entry points

NOTE : RJ-1, RJ-45,DB-9, DB-15 & DB-25 Protectors can be configured for any voltage on any pin

NOTE: RS-232, RS-422, RS-485, or any other signal configuration, can be supplied with screw terminals

<> <> <>

CONTROLLER PROTECTION:

Controllers are often neglected when system protection is designed.
Not only AC Power, but Signal and Control lines often suffer spike & surge damage
Consult us to help specify correct protection levels for your controller installation.
Protectors can be designed with wire leads, screw terminals or commercial connectors.

View designs with screw terminal connection
AC or DC Protection, at virtually any voltage, can be engineered
Our Wire-in and Severe Duty units are widely used for standard AC voltages
