Professional ESM 20000i Mains-Powered Electric Fencing Energiser

The Rutland Professional ESM 20000i Mains Energiser is one of the most powerful electric fence energisers available from Rutland (a brand of Kerbl). With a 20 Joule (J) stored energy and a 15 Joule (J) output energy, it's designed for the most demanding electric fencing applications.

 This energiser is a true powerhouse, built for extremely long fences,Capable of electrifying very extensive fence lines, even up to 70 km in ideal conditions.   Its high output allows it to maintain a strong deterrent shock even when significant grass, weeds, or branches are touching the fence, which would short out less powerful energisers.

 This energiser is specifically recommended for large animals like bulls, adult cattle, sheep, goats, and horses. It's also highly effective for deterring persistent wild animals (e.g., deer, wild boar, predators).It is suitable for  Professional and large-scale farming operations: Where reliable and consistent high power is essential.As a mains-powered unit, it offers continuous and stable power output makes it a good option for use in permanent fencing.

Key Features & Benefits (The "Intelligiser" Series):

• Ultra-Powerful Output:

• Stored Energy: 20 Joules (J)

• • Max. Output Energy: 15 Joules (J)

     
    This immense power ensures a strong, reliable shock, even under the most challenging conditions

• Intelligent Fence Monitoring & Adaptation (Intelligiser Technology):

• Extra-large, clearly-arranged, permanently lit digital display: Provides comprehensive and easy-to-read information on the energiser's status.

•  

  LED Bar Graph: Allows for quick visual identification of the current fence condition from a distance, making it easy to spot potential issues (e.g., shorts).

• Fence Impulse Optimally Adapted to the Fence Load: The energiser intelligently adjusts the pulse based on the resistance of your fence line. This ensures maximum effectiveness and security, as the pulse is optimized for current fence conditions (e.g., varying vegetation).

• Minimal Energy Consumption through Rutland Powertronic: Despite its high power, it's designed for energy efficiency, helping to manage running costs.

   

• Dual Power Option (230V Mains with 12V Capability): While primarily a 230V mains unit, it often comes with a 12V connection cable, allowing for greater flexibility if a temporary 12V battery power source is needed (e.g., during power outages or for specific mobile sections).

• Micro-controller Controlled: Ensures precise, reliable, and consistent operation.

• High Safety Standards: Designed in compliance with the latest safety regulations, prioritizing the well-being of livestock and users.

• High/Low Mode: Provides the ability to switch between different power levels or simply turn the unit ON/OFF for greater control. Some models also have a time-delayed safety feature, where the energiser waits before increasing power when a sudden load change is detected, allowing anything trapped to release itself.

   
  Robust Construction: Built to withstand the demands of professional agricultural environments.

• Includes: Fence and earth connection cables, 230V power pack, and 12V connection cable.

• Warranty: Typically comes with a generous 5-year warranty.

   

Detailed Specifications (ESM 20000i):

• Power Source: 230V Mains (with 12V option)

• Stored Energy: 20.00 Joules (J)

• Max. Output Energy: 15.00 Joules (J)

• Max. Voltage (Open Circuit): 10,000 V

• Voltage at 500 Ohms (Load Voltage): 7,900 V (This is the effective voltage under a typical fence load, indicating its formidable shocking power).

• Max. Fence Length (without vegetation): 70 km

• Max. Fence Length (with medium vegetation): 23.3 km

• Max. Fence Length (with heavy vegetation): 7.8 km

• Approx. Number of Electrifiable Nets: 40 (This refers to standard 50m multi-strand electric netting)

• Recommended Earth Posts (1m): Minimum 3 (For an energiser of this power, a robust earthing system is absolutely critical. Some professionals might even use more, or longer, earth rods).

• Power Consumption: 0.24 A - 1.18 A

Installation Considerations:

• Dedicated Power Supply: Ensure a stable 230V mains power supply is available at the installation location.

• Indoor/Sheltered Installation: While robust, it's best installed indoors or in a fully weatherproof, well-ventilated enclosure to protect it from harsh weather.

• CRITICAL: Earthing System: For a 20J energiser, a comprehensive earthing system is paramount. You must use at least 3 x 1-meter (or longer) galvanized earth rods, driven fully into moist ground, spaced at least 3 meters apart, and connected with high-quality galvanized wire. In very dry or sandy soils, even more or longer earth rods may be necessary to achieve optimal performance.

• High-Voltage Lead-out Cable: Use only appropriate, insulated high-voltage lead-out cable to connect the energiser to your fence line and earthing system.

• Fence Line Quality: To maximize the benefits of this powerful energiser, ensure your fence lines use high-quality, highly conductive wire (e.g., 2.5mm high-tensile steel wire, quality poly tape/rope with good conductors) and robust insulators.

• Warning Signs: Place "Electric Fence" warning signs at regular intervals, especially where the fence borders public access ways.
