Single Channel Coaxial HD-CVI, HD-TVI AHD Video and 24Vac Surge Arrester.


HD-TVI, HD-CVI and AHD surge arrester with a 2KA rating, providing the perfect blend of premium performance with ease of installation. The HDPA-024 overs protection at both the low-end and high-end; the low-end protection is via fast responding TVS (Transient-Voltage-Suppression) diodes, and the top-end protection is via GDT (Gas-Discharge-Tubes). The HDPA-024 needs an electrical earth connection onto which the surge energy is safely discharged.


Warning!   As both ends of the data communication cable need protection, this may introduce resistively coupled transients in your system.

Resistively coupled transients cause most of the lightning damage to electronics and electrical equipment. These transients are caused by a difference in potential between two connected electrical earth points.
