The speedrite 12000i is our best-selling model for large to medium size farms. The speedrite unigizer delivers a powerful punch and suitable for all types of livestock including cattle, horses, and small animals.

Fully featured. Remote control capable. Can be used in 110V, battery or solar power applications, providing convenient, versatile livestock control.

Powers up to 90 miles (500 acres) of fence
12 J maximum output energy (16 J stored energy)

• Cyclic Wave™ technology.  Provides a cleaner, more powerful pulse, maximizing the energy that travels down the fence for optimal stock control

• Bi-polar technology.  Enables the user to power a fence system to perform exceptionally well in dry, low conductive soil

• Solar compatible.  Electrify your fence with solar power by connecting solar panels to any Speedrite Unigizer. The solar panels charge the battery connected to the Unigizer, for reliable livestock control.  Recommended solar panel - 120 watt

• Remote capable (ST102).  Using a Speedrite fence remote (with remote capable Speedrite energizers) enables you to switch the energizer on or off from anywhere along the fence line.  This makes it easy to manage repairs and maintenance. 

• LCD Voltage Display.  Displays output voltage, battery voltage and earth voltage. LCD is backlit for viewing in poor light conditions

• Indicator lights.  Easy to read light bar display provides an instant measure of the Unigizer output voltage and battery condition for quick fence diagnostics. The LED display shows red when heavily loaded

• Battery saver.  Microprocessor technology automatically adjusts the output energy depending on the battery condition. This feature extends battery life and is particularly efficient when used in solar installations

• Day/Night sensor.  Automatically adjusts pulse speed to contain or exclude animals based on day or night conditions

• Large terminals.  Mounted on the front of the energizer casing for convenience, these large terminals are easily adjusted and accept up to two fence wires. The slotted terminals make inserting wires and getting a good connection easy

• Low Impedance.  Designed to deliver power to the end of the fence even under heavy load e.g. foliage, undergrowth

• Low Interference.  Cyclic Wave™ technology delivers outstanding fence performance and helps to minimize electromagnetic interference in line with international EMC standards

• Ground monitoring.  Indicates ground system problems by monitoring the level of voltage around the ground system

• Versatile mounting options.  Can be mounted on a wall, post or fence wire. Choose indoor or outdoor installation, depending on your fence location and power supply

Adjustable power and pulse speeds

 Half voltage terminal.

Includes 110V power adaptor and battery leads.
