Isolation Dongle for CPE

Specifications

The Model 2391-A Isolated Dongle is designed specifically for communications installations where grounding systems are not present, or where the ground rod is missing due to theft or ineffective due to corrosion. Ungrounded communications circuits at the customer location can pose a damage risk to equipment due to lightning and other transient events. Normally, these transients would be shunted away from the customer’s equipment where proper grounding and primary protection exist.

The Bourns® Model 2391-A utilizes multiple Bourns circuit protection technologies in its design to create a dongle that blocks transient events up to rated limits without the use of a ground.
