Cable length high-voltage cable
1 x approx. 4 m (± 10%)
Fuse in the fuse holder
500 mA
High-voltage contact plates
6 pieces, approx. 40 x 40 x 1,5 mm each
Dimensions basic instrument
approx. 125 x 70 x 31 mm (without cable entry point + LED).
Suitable for vehicles with Can Bus.
Cable for terminal 15
If this cable is connected with “positive“, the marten defence disconnects. The marten defence switches on if it is connected with “negative” or does not receive any signal.
Chases away martens by means of small high-voltage plates charged electrically to approx. 200 - 300 V/DC through electric shock in the engine compartment of the vehicle (only weak current pulses that chase the marten away, but do not kill it) and through strong, aggressively pulsating ultrasonic sounds. Extremely low power consumption (< 0.005 A), switches the battery voltage of < 11.5 V automatically off (does not discharge the battery completely if vehicles are being parked for quite some time).

Available accessories:
Z115 - "Ground"-Mat for electroshock devices
