The TWIST-LGC+PWR-12VDC protection device against induced impulse voltages (lightning protection) for the protection of video surveillance devices (video cameras, monitors, video servers, video recorders) on video signal lines (coaxial cable) and 12 V DC power supply from high-voltage lightning discharges, powerful electromagnetic fields, high-voltage pulse leads.

Grounding is required for proper operation of the device!

Protection on the video signal line is passive with recovery. Limits the swing of the signal level on the protected device to about 4 V.
Power line protection – active type.
The operating voltage range corresponds to the possible spread of voltage on the video camera (taking into account the transition to backup power from the battery).
In the event of impulse interference, devices protected by power lines are disconnected from the line for the duration of the overvoltage. Recovery of the operating state occurs automatically when the voltage drops to a safe level.

Video signal protection:
• Number of degrees of protection: 2
• Frequency range: 10 Hz - 10 MHz
• Irregularity of the frequency response (10 Hz - 10 MHz): no more than 1 dB
• Protection threshold voltage: 3.5 V
• Trigger time no more than: 200 ns
• Allowable impulse 10/1000 μs charge current in the line: 100 A

Power protection:
• Number of degrees of protection: 3
• Supply voltage: (10 - 14.3)
• Load current and type of fuse installed: no more than 1 A
• Trigger/recovery threshold voltage: 14.5/13.9 V +/-2%
• Trigger time: slightly more than 200 ns

• Current consumption of the protection circuit in operating mode: no more than 30 mA
• Operating temperature range: -40 ... + 50 ° C
• Overall dimensions: 42 x 77 x 25 mm
