Polyphaser RF Surge Protectors
PolyPhaser RF surge protectors and lightning arrestors protect against power surges, electromagnetic pulse (EMP) and high-altitude EMP (HEMP) that are caused by lightning or other strong electrical changes. They allow the desired frequency to pass through the cable while suppressing a DC surge.
RF surge arrestors filtering technologies are designed to withstand the high currents of a lightning strike. These devices are always “on” as they typically consist of an inductor to ground, providing superior protection.
PolyPhaser RF surge protector devices feature filtering technology that incorporates their patented spiral inductor, designed specifically to handle high-current lightning strikes. Competitive arrestors use a simple inductor coil to ground. Typically these simple inductor coils have lower lightning surge ratings than the PolyPhaser-engineered spiral inductors.
Many RF surge arrestors utilize circuit protections devices such as diodes, metal oxide varistors and gas discharge tubes. Some RF arrestors may use a simple standalone gas discharge tube, which does not offer very good protection as it typically requires several hundred volts before activating. The PolyPhaser GX series utilizes a hybrid circuit that incorporates the response time of a diode, while also adding the current handling capabilities of metal oxide varistors and gas discharge tubes. The result is an RF surge arrestor with one of the lowest energy and voltage let-through ratings on the market.
