High-voltage Electric Shock Device for Animal Deterrence

This High-voltage Electric Shock Device for Animal Deterrence generates a pulsed high-voltage, low-current output designed to deter animals from entering protected areas via an electrified wire or tape. It is commonly used in agriculture, property perimeter protection, infrastructure security, and vehicle anti-rodent applications.

The output is configurable between 5,000 and 12,000 volts, with a pulse energy of 1–3 joules and a current limited to approximately 4–5 milliamperes per pulse. The pulse duration is brief (typically under 1 millisecond) and repeats at intervals of 1 to 2 seconds. This combination produces a sharp but safe deterrent effect—sufficient to startle and condition avoidance without causing tissue damage or long-term harm to animals.

Operating Principle

When an animal contacts the electrified line, it completes an electrical circuit through the animal’s body to ground. The high-voltage pulse passes through the contact point, delivering a momentary shock. Because the current is limited and the pulse is intermittent, the experience is unpleasant but non-lethal. Animals typically learn to avoid the area after one or two exposures, providing a long-term behavioral barrier without the need for traps, chemicals, or ongoing maintenance.

Technical Features

Voltage output: 5,000 – 12,000 V (adjustable per model)

Pulse energy: 1.0 – 3.0 J

Current per pulse: ≤ 5 mA (peak limited)

Pulse interval: factory-set at 1 pulse/second, adjustable on request

Power supply options: AC 110–240V, 12V DC battery, or solar panel (panel sold separately)

Standby power consumption: < 2W, enabling extended battery life (weeks on a full charge)

Weather protection: IP65-rated enclosure, operating temperature range -40°C to +55°C

Status indication: LED light shows power-on and pulse activity

Safety protections: built-in overcurrent cutoff, isolation transformer, and automatic pulse termination after continuous contact (to prevent overheating)

Applications

This device is deployed in the following scenarios:

Agriculture: protecting orchards, vineyards, and crop fields from deer, wild boar, and other large herbivores.

Livestock fencing: containing or excluding animals without permanent barriers.

Property security: preventing wildlife intrusion into residential gardens, commercial lots, and storage areas.

Infrastructure: deterring rodents and martens from damaging cables, insulation, and vehicle engine compartments.

Industrial sites: keeping animals away from sensitive equipment and outdoor installations.

Performance and Reliability

Our pulse generators are built with components and circuit designs derived from our core high-voltage power supply systems, which have been developed over 20 years for industrial environmental applications (electrostatic precipitation, plasma treatment, and exhaust gas purification). The same engineering standards—particularly in voltage regulation, arc suppression, and thermal management—are applied to this deterrent unit.

Each unit undergoes a full functional test before shipment, including output voltage calibration, pulse energy verification, and insulation resistance testing. Mean time between failures (MTBF) is estimated at over 50,000 hours under normal operating conditions, based on accelerated life testing of critical components.
