www.furse.comESP CCTV Series
Camera telemetry or control lines should be protected with a suitable Lightning Barrier from the ESP D or E Series. Protectors for the power supply
to individual cameras (e.g. ESP 240-16A) and the mains supply to the control room (e.g. ESP 240 D1) are available. For coaxial RF (ESP RF Series)
cable protectors and CATV systems (ESP CATV/F) are also available.
Technical specification
1
Nominal voltage (DC or AC peak) measured at
<10 µA leakage.
2
Maximum working voltage (DC or AC peak) measured
at 5 mA leakage.
3
Capacitance < 30 pF.
4
The maximum transient voltage let-through of the
protector throughout the test (±10%), line to line &
line to earth. Screen to earth let-through voltage will
be up to 600 V (with 5 kV 10/700 test), when
protector is configured for use with non-earthed or
isolated screen systems. Response time < 10 ns.
5
Test to IEC 61000-4-5:2006, ITU-T (formerly CCITT)
K.20, K.21 and K.45,Telcordia GR-1089-CORE,
Issue 2:2002, ANSI TIA/EIA/IS-968-A:2002 (formerly
FCC Part 68).
6
The installation and connectors external to the
protector may limit the capability of the protector.
