Add some Static and Lightning surge protection to your DC WISP equipment.
Fits in APC PRM4 or PRM24 Chassis. (Don't use in far left slot on PRM24, screws could short to the chassis.)
Chassis not included.
No warranty or guarantee of protection. This is just another layer of protection for your system.
2 sets of binding posts that can accept standard banana plugs.
Gold plated contact surfaces on board.
Does not provide any fusing.
Area to affix 1/2" label tape.
Locations to zip tie your cables in place to help prevent them from pulling out of the binding posts.
Tested on +24 and +48V Systems. Should work on -48V systems too, just keep the voltage differences under 57 Volts. The tubes are specified to arc over at somewhere between 60 Volts and 90 Volts.
Don't insert/remove module if powered up, it's easy to accidentally short the screws out on the chassis or other modules.
