This DEHN Lightning Current Arrester Module (MPN: 909704) is designed for users needing robust surge protection for data and M&R applications, specifically TV/radio line protection. Its key benefit is safeguarding sensitive equipment from lightning-induced surges with a high discharge current capability and low residual voltage. A potential caveat is its specialized application, primarily for 75 Ohm satellite and broadband cable systems.

The primary purpose of this DEHN module is to protect data and M&R applications, specifically TV/radio line systems, from damage caused by lightning-induced surges and overvoltages.
It is designed for 75 Ohm satellite and broadband cable systems, utilizing standard F-connectors.
The device operates effectively at frequencies up to 24,000 MHz (24 GHz).
You connect it inline with the coaxial cable using the F-connector. One cable connects to the input, and the other to the output, with proper grounding established.
It has a nominal discharge current (8/20) rating of 10kA, and a maximum surge current rating of 1.5kA for the DC arrester specification.
No, this is a passive surge protection device and does not require external power to function. However, it must be properly grounded to divert surges.
Class A shielding, as per EN 50083-2, indicates a high level of electromagnetic compatibility, meaning the device effectively prevents interference from entering or leaving the signal path.
While effective for its intended purpose, it is specifically designed for 75 Ohm data/RF signal lines. For AC power protection, different DEHN products are required.
Verify that the coaxial cables are correctly connected to the 'in' and 'out' ports of the arrester. Ensure the F-connectors are fully seated and tightened. Check that the module is not damaged and is properly grounded.
Inspect all cable connections for secure fitting. Ensure the module is correctly installed on a DIN rail and properly grounded. If the issue persists, the module may have been subjected to a surge and might need replacement.
While the arrester significantly reduces risk, extreme surge events can still potentially cause damage. Ensure the arrester is correctly installed and grounded. Verify that the maximum continuous voltage (60V DC) and surge current ratings are not exceeded by the application.
