The CA series
of surge protection devices prevents
surges and transient overvoltages conducted through co-axial
cables from damaging electronic systems such as telemetry outstations.
They protect vulnerable equipment without affecting normal operation,
passing high frequency signals with little attenuation while
diverting surge currents safely to earth and clamping output
voltages to safe levels.
Receivers & transmitters are particularly vulnerable
to damage from the effects of lightning. Their remote locations
and physical construction make them a likely target for lightning
activity. The use of semiconductors and integrated circuits
in transmitters and receivers has rendered them particularly
prone to damage from these disturbances.
Excellent performance levels are achieved using high
energy gas discharge tubes, in precision engineered compact
enclosures, to produce superior surge suppression and transmission
characteristics. The protection circuitry is capable of diverting
10kA impulses whilst the brass bodies and connectors are silver
plated and are designed to meet harsh environmental requirements.
A wide range of connector styles is available to suit
all application requirements with a choice of working voltage
and characteristic impedance provided for most of the series.
In addition, bulkhead mounting options are available where insertion
into a panel is preferable.
Typical applications include the protection of radio
telemetry systems, mobile communications base stations and where
high induced voltages may be present in aerial systems. |
