SURGE PROTECTION

The SW720A camera provides internal surge protection for all of the power, data and

video signals.

1.) The AC line power connections are provided with 275 volt 135 Joule MOV surge

arrestors rated for 6000 Amp pulses. A 3A SMT fuse is included in the primary

circuit to prevent catastrophic printed circuit board damage in the case of gross

AC line input overloads.

2.) The video signal lines incorporate a two stage protection circuit consisting of a

primary 90V gas discharge tube, followed by a high speed, low capacitance 6.2V

2kW peak power transient voltage suppressor.

3.) The data signal lines incorporate a two stage protection circuit consisting of a

primary 90V gas discharge tube, followed by an 18V, 300W, 40A transient

voltage suppressor.
