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.
