Does anyone know if the supplied DC power bar on the CTT SensorStations have built-in surge protection? I can’t find any documentation online. Thanks! @user80
Barry, I’m not sure I’d consider it fully surged protected, though the manufacturer claims the following:
“Offers automatic protection against short circuit, overload, over voltage, over current, and high temperature. Uses hiccup mode and auto-recovery after fault conditions are removed.”
In the past, I’ve had some pretty nasty surges appear to kill the power supply, but the good news was that I could just swap it out with a new one $15 on Amazon, or $25 via CTT) for a relatively cheap replacement cost - and the board was protected.
The protections you’re quoting apply to the output of the power supply and don’t say anything about the input.
Surge protectors generally operate by shorting wires together to dissipate the power, mostly between neutral and line. If the surge is powerful enough it can “blow up” the protection device, which may either cause a short or an ineffective protection device. In the first case you’re out of power in the second case the second surge will take out the power supply…
Many consumer surge protection power strips have pretty questionable surge protection. Bottom line: if you’re just generally concerned it may be best to have a replacement power supply handy. If you set-up in a location that is frequently subject to surges due to lightning, for example, then you should consult someone knowledgeable 'cause that also affects the antenna cables big time, i.e., you need to look at the whole installation.
