DC Block and DC pass Coaxial Surge Protectors
DC Block and DC pass Coaxial Surge Protectors
In the event of a power surge, there are a few things that
need to happen to excess/ unwanted energy. First, the surge needs to be
directed to ground as quickly and easily as possible through the earth rod.
Second, as much of the energy as possible needs to be absorbed so that it does
not enter the system and potentially damage vital components. Coaxial surge protectors will safeguard your equipment from power surges that are not dissipated effectively by the ground rod.
Of note is that the surge protection device MUST be grounded as well.
When grounding, it is acceptable to tie this ground into the existing internal
grounding system within the control panel.
DC block and DC pass coaxial surge protectors are two types of coaxial surge protectors that are designed to protect electronic devices from voltage surges on coaxial cable lines. However, they differ in how they allow or prevent the flow of direct current (DC) voltage. Click here to find your ideal coax surge protector.
A key consideration when purchasing units is whether they will pass or block DC voltage within the coax cable.
DC Block coaxial surge protectors are designed to
block the flow of DC voltage while allowing the flow of radio frequency (RF)
signals. This type of surge protector is often used in applications where it is
important to isolate the DC voltage from the RF signals, such as SCADA, VHF/UHF
Radio and cellular systems.
DC Pass coaxial surge protectors, on the other hand, are designed to allow the flow of both DC voltage and RF signals. This type of surge protector is often used in applications where the DC voltage is required to power equipment, such as in some closed-circuit television (CCTV) systems.
Coaxial Surge Protection devices are engineered for low voltage let-through and superior RF performance, DC pass lightning protection devices offer superior performance to protect sensitive Tower Top Amplifiers (TTA) or active antenna systems where DC voltage is required such as GPS, 4G, 5G, and RET (Remote Electrical Tilt).
In summary, the main difference between DC block and DC pass
coaxial surge protectors is how they handle the flow of DC voltage. DC block
surge protectors block the flow of DC voltage, while DC pass surge protectors
allow it to pass through. The choice between the two types of surge protectors
will depend on the specific requirements of the application
