Actual fence performance will vary depending on fence construction, vegetation, grounding, maintenance and other conditions.
Built-in Bluetooth® and Wi-Fi connectivity brings fence management directly to your smartphone.
Using the Datamars Pro App, you can monitor and control the U20000W locally or remotely when properly connected.
Check fence performance from your phone
Monitor the energizer locally using Bluetooth
Connect through Wi-Fi for remote internet access
Receive alerts when connected through Wi-Fi

Remote internet functionality requires a suitable internet/Wi-Fi connection.
One of the biggest advantages of the U20000W is its flexible power configuration.
The energizer can operate from mains, battery or an appropriately configured solar/battery system.
For even greater reliability, mains power and an external 12V battery can be connected simultaneously. The external battery can provide backup fence power during a mains power outage.
Battery sold separately.
The U20000W is an excellent choice for large and demanding electric fence installations, including:
Beef cattle operations
Dairy farms
Sheep and goat operations
Horse fencing
Rotational grazing systems
Large high-tensile electric fences
Multi-wire perimeter fences
Remote pasture systems
Commercial livestock operations
Its 20-joule output provides the power needed for long fence runs and challenging fence conditions.
Speedrite's Cyclic Wave™ technology is designed to deliver continuous power along the fence system, helping maintain effective electric fence performance over long runs.
For large farms where fence power needs to travel considerable distances, efficient energy delivery can make a major difference.
Built-in LED indicators provide quick visual feedback of energizer output.
Instead of guessing how your energizer is performing, you can quickly check the unit and identify potential fence problems.
The U20000W features an improved output terminal design inspired by Speedrite's flagship W-Series energizers.
The heavy-duty split-bolt terminals provide secure connections and make it easier to connect multiple fence wires.
The U20000W is compatible with a Speedrite Fence Remote, allowing a compatible remote to switch the energizer on or off from the fence line.
Fence Remote is sold separately and is NOT included with this energizer.
