Electro Standards Laboratories Surge Suppressor 309010

Model 303 protects your computer's data interface from destructive transient voltages caused by lightning, brownouts and rolling brownouts! Sure-Guard Surge Suppressors are designed to limit transient voltages that damage hardware and disrupt data transmission between computers at the DB25 Serial interface. Data Communications line protection can no longer be overlooked. Its role in a well-managed effective system is essential to the overall welfare of the data-processing environment. The cost of protection from lightning, industrial disturbances, motor switching, and magnetic/electrostat ic induction from power lines is surprisingly inexpensive and maintenance free. System reliability depends upon a well-protected electrical environment. UPS and power line surge suppressors do not provide complete protection for data lines. Add Sure-Guard surge protectors to protect your data lines.
