Rack Mount DC Power Line Surge Protector



Rack Mount DC Power Line Surge Protector

Gas Discharge Tube design to be used with the popular   PRM4 and PRM24 1RU Rack Mount Chassis made by APC.  We also sell a PRM4 4 slot rack that is Din Rail Mount.

DC Powerline surge suppressor – protector. Protects input and output separately. Lumped inductance between input and output shunts surges coming from either direction to ground while impeding their flow to the other side of the device. Both semiconductor surge suppression and Gas Discharge Tube for fast and large surge protection. Double Multi-Stage protection devices provide 4 X the protection of conventional protection devices.
