1、[With Alarm] Direct current and alternating current can be switched for use, with an alarm, a siren will sound when the fence fails, so you can use it with confidence. 2、[Simple To Use] When the power indicator of the host is on, it means the power is on, the high voltage pulse indicator flashes, indicating that the pulse is working normally, and when the fault light is on, it means that the fence or the host is faulty. 3、[Display] The input voltage and power display instrument can display the voltage and power of the power supply or battery in real time. When the display is lower than 12V, the machine will alarm and stop working to protect the battery from over discharge. 4、[Power Supply Method] The ground terminal is connected to the earth through the wire ground pile, and the power adapter can be used for power supply, and the customer can supply the battery or the solar power system by himself. 5、[Safe To Animals] The high voltage positive 8KV and 12KV output terminals form 8KV and 12KV high voltage pulse electricity with the ground terminal, which is not harmful to humans and animals. Item Type: Pulse Electric Fence Host Material: ABS Product Size: Approx. 24 x 12 x 7.5 cm / 9.4 x 4.7 x 3 in Bottom Hole Distance: Approx. 22 x 7 cm / 8.7 x 2.8 in Pulse Period: 0.75S-0.3S Output Energy: 3 joule Alarm: Yes Cable Length (The Longest Cable Distance): 10km (single wire) Specifications: 10km alarm host Application: Animal husbandry protection Applicable Scene: Outdoor Applicable Animals: Pigs, cows, sheep, horses, dogs and other animals Weight: Approx. 1388g / 49oz Electric fence use and benefits: Perhaps the most widely recognized method of animal control is the electric fence system. Electric fences not only control domestic animals and livestock, but also have many important uses, including confining wild animals Type groups of animals, allowing crop and forage rotation, keeping animals out of trees, rivers, roads and damaged land, electric fences have enabled newer grassland management techniques, better grassland management is better for herders , Fixed and movable electric fences are used for grassland zoning to ensure the uniformity of grassland grazing and animals on the grassland; only in this way can the forage keep freshness and good palatability, as well as maintain the appropriate height of the grass, and ultimately play a role in Increase milk and meat production in grasslands Function: 2. Pulse adjustment: Pulse cycle adjustment knob, rotating this knob can adjust the pulse to form a discharge cycle between 0.75 seconds and 0.3 seconds 3. Alarm: Alarm output socket, output 12V when alarming, used to connect alarms with power less than 10W, if you need to connect alarms larger than 10W, you need to connect an external relay control power supply to supply power to the alarm, and directly connect an alarm larger than 10W The device will burn out the wiring inside 1 x Pulse Electric Fence Host 1 x Power Adapter 1 Pair x Battery Clip 1 x Alarm 1 x English Manual
