SurgeX makes the best surge protectors, but new, they are expensive. Here is an excellent in-depth article, that includes a teardown, on one of the SurgeX products:
You'll note the heavy duty construction of the SurgeX product in the article, which is great, because that makes use of used SurgeX units practical.
Don't consider SurgeX products like Defender or Next Gen. They appear to be a different design.
Here are thoughts on two alternatives:
o SurgeX SX1115RT
This is a 15A surge protector with over and under voltage protection and surge protection. The surge protection essentially removes everything over 170V or so volts peak. 170V peak is the peak voltage of a 120V sine wave. The teardown article describes some of this.
This surge protection appears to also remove the spikes and the like from light dimmers, ECM motors, and other sources of line disruption. Most of the design is covered by patents that expire in 2025 so SurgeX is really the only source of protection at this level. The protection is series mode so none of the nasties are shunted to the ground conductor.
If you have a 20A outlet available then you can also consider a SX1120RT. These are essentially the same as the 15A units, but are available used in larger numbers at about the same price.
o SurgeX Flatpack SA-82
This unit has overvoltage protection and the same type of surge protection as described above. It has two outlets and a current limit of 8 amps. As described in the teardown above of a SurgeX product, this item is overbuilt with 12 gauge, 600V boat wire, for example.
Two of the SA-82 units would take up two 120V, 15A outlets and provide 4 protected outlets. The power cord is removable from an SA82 so a shorter or longer cord can be purchased from say Monoprice to make for a neater installation or provide service to equipment in separate locations. A shielded power cord can also be used, which may provide benefits if signal cables are located within a few inches of the power cord; draping down the back of a rack or on the floor, for example.
To find used units, go to eBay, search for SurgeX, sort with highest prices first and start at units around $150 around page 4 and go down in price you'll find some good opportunities, even at $100 or less for either the SX or SA units. The units made in North Carolina are newer than the units made in Pennsylvania (New Frontier Electronics) although it isn't clear this makes a lot of difference.
