Selecting the Right Equipment
There are a number of companies that sell quality surge suppressors such as Sutton Designs, APC, and Panamax.
When you are looking for a surge suppressor, consider these things.
Expect to pay at least $50 for a good quality surge suppressor.
The surge suppressor should be a UL 1449, 497, and 1283 listed for surge suppression, modem surge protec-
tion, and RFI/EMI noise filtering respectively.
The surge suppressor should have diagnostic LEDs that verify good AC ground, proper wiring, and proper
surge operation. Lighted on/off switches are not recommended since they can produce electrical noise.
The Joule ratings should be a minimum of 480 Joules for the AC surge circuit.
The Joule ratings should be a minimum of 240 Joules for the modem.
The modem surge circuit should present low capacitance to the modem line or it will slow the transmission
rate. Capacitance should be specified at less than 50 picofarads.
Quality surge suppressor manufacturers generally offer a lifetime warranty.
Consider obtaining a protected equipment coverage policy which insures the equipment in the event of surge
damage.
The devices that will be attached to the computer also need to be surge protected.
